Hi first time here, excellent site and user friendly. I recently came across this air compressor it had been sitting outside for the last 25 years and not in use it was in waist high grass next to and old workshop that was being torn down. The Tank has a build date of 1969, WP 200 built by Kargard, the pump is Jacuzzi Bros I’m guess its a little older than than the tank but not sure. The motor is big and heavy, the tag is barely legible and not at all in some places I think it’s a Dayton,… Read more »
There is no doubt in my mind that this is a home-brew machine. Painted up pretty nice though!
Can’t tell you much as info on Jacuzzi pumps is almost as rare as hen’s teeth.
That might just be because the people with the info don’t come here, though.
Hi First time here, very informative and user friendly, thank you. I recently found this air compressor outside in waste high grass next to and old workshop that was being torn down, I had to use a shovel to dig it out where it had started sinking into the earth over the years after each torrential rainstorm here south of Houston Tx. The property was being sold and was being clean up all I had to do was dig it out and load it up and it was mine. I’m guessing it’s at least 200lbs the tank is a Kargard… Read more »

Trying to confirm the compressor model number, year of manufacturer and any additional info. Also, any idea what it may be worth running or not? Thanks.
Depends on where it is and whether it runs, to a lesser extent. That’s a quality machine.
Thank you for your reply. It does run. Do you know where I may find additional information, specifications, etc?
I hope Roger will be by with some more. Meanwhile, It is a Kellog, But I’m not sure about that motor, It may be a lower powered version, or maybe someone replaced the OE motor. The motor speed and power largely determine the output pressure and/or volume depending on how it’s geared. Is there a plate with horsepower, current, and RPM on it? Also, is there a plate or direct imprint on the tank? That would have date and some rating info on it as well.
Might be a model 340 or even a 352 pump – some images attached with some spex
Well, crap. Attachments seem to be broken again.
Can anybody tell me about my Ford Air Compressor?
Hey Christopher,
Can you upload some images so we can see it? Otherwise we’ve not got much hope of identifying it!
Cheers
I’ve been trying to upload images but they haven’t been able to attach for some reason
Hey Christopher,
Try to upload the images now – I’ve just cleared the system.
If you’re still having issues, please send images to aboutaircompressors @ gmail.com and I’ll get them uploaded!
Cheers
I need help identifying this compressor…Thanks!
Hey Dan,
Are you having trouble uploading images? I just tested and it seems ok – let me know
Cheers
Hello, I posted in wrong section before hopefully this is the right one. Im in big need of anyone’s help, trying to find piston rings, and original color and any other helpful information about this 100 year old relic. The motor dates back to 1916 patent. Don’t know about pump. It runs and works, I want to keep this in my family for another 100 years lol. They sure don’t make them like this anymore!
Try Hastings for rings. Measure carefully, and they can often find a fit.
If the brushes wear out, you’ll probably have to “repurpose” brushes for something else.
Good luck.
Looks like a DeVilbiss paint spraying system using an old Saylor Beall compressor pump. Saylore Beall might have some info but it is probably long obsolete.

Looking for lots of info, greatly appreciate all help. K.R. Wilson SN# 207. Only building 5psi but still pumps. Ultimate goal repair manual or service manual. Thank you
Hey Randy, please could you provide some pictures? It also sounds like you’ve successfully identified the air compressor – so if you’re looking for some specific advice on an air compressor that won’t build pressure – take a look at this article about fixing an air compressor that won’t build any pressure.

can you please help identify this compressor? We need to find a motor for it.
thank you
Never heard of this name before
Hope this picture loads.
I have a compressor that I found when renovating an out building. Brand new still attached to a 1×6 on the bottom and cardboard stapled to the board. Would like to know what it is and if it is useful.
Hey Keith – Please attach images otherwise we can’t help identify the compressor. The image upload is now working, but you’ll still need to make sure the images aren’t enormous in file size
Hi,
Am looking to restore this old Air Compressor. Now that i’ve got some of the paint off, I can see a logo, CBS, maybe a model number, H 30424, a date, 16th May 1957 (happy 64th birthday!!) And has S400 stamped on the crank shaft housing. It has two small pistons but looks to not have piston rings but does have a cap on the top of the piston, possibly leather? Looking for any information and tips for restoring.
Thanks,
Nic.
Hey Nic – any pictures to help us out?
I’ve come across an air compressor made by US Curtis manufacturing.
I posted a picture of the serial number. Like to know a value and some history about the piece.
COPELAND COMPRESSOR

Hi wanting to sell compressor but having difficulty finding information
Hi, I was given a large air compressor and I wanted to pull up any info I can on it before setting it up. It’s coming from an old mechanic shop.
Thanks

This air compressor pump was mounted on a board. I put it on this tank and it pumps up to 120psi, but it sprays oil out the shaft on the other side from the pulley. Anybody tell me what make it is?
This is a Kellogg 210 and you are missing the welch plug on the end of the crankcase. If you can’t find the OEM part, maybe there is a freeze plug from a car engine that might fit. You can also get hole plugs at Lowe’s that might work.
It’s a Kellogg 201. It needs a steel plug in the end of the case.
I found the plug and put it back, but it has popped out twice again. I put a cinch strap around it and so far it is still on. Much less oil coming out. thanks.
Hi. I have an old compressor that I can not identify. Hoping someone more knowledgeable than I can figure it out. There are two tags on it. One simple says: Model 533 and serial: 638326. It’s clearly 2 stage. The air filter is marked Dollinger but I think that’s only the mfg of the air filter and not the pump. I’ve had it for 40 years and it was old when I got it. Any help appreciated!
Pix might help. If you tried to attach pix, it didn’t work, apparently.
@Doug, thanks for the reply. I did try. They would not load for some reason but looks like these new ones did. I had this on a tank with 3HP motor turning at about 450 RPM. I’d guess it was pumping about 15CFM. It looks like a Kellogg but I can’t find any markings. I need to replace the valve on the air intake as it leaks… but I can’t figure out what parts are a fit.
Someone was having an off day at the Kellogg factory. It’s a 335 not a 533.
Seriously? Must have been a “Monday” compressor. Wow. Great to know. Thank you!
Hi, I have a compressor motor that slows down under load. I have checked the start capacitor and the run capacitor and they both check good.
That leaves the centrifugal switch. It is what connects the run capacitor to the motor right after is starts. Usually found inside the back end of the motor.
Good luck.
Hello. I bought an old compressor pump which needs parts but I know nothing about it or its age. There is a name in the cast but after searching online I can’t find anything. Any help would be appreciated thanks.
Looks like an air brake compressor or equipment controls compressor. The tag info might help. I’m getting a Westinghouse vibe from it, but that’s just a guess.
Here is the tag image.
Looks like a badge is hiding under the paint just above that tag. Maybe carefully chip away that paint and you will get some more info on this unit.
This is an old Clayton Dewandre air compressor.

I have determined the compressor to be a Quincy Model A-4, ROC 7. If anyone has experience, manuals or diagrams for this compressor I would be most appreciative if you could share those.
If you haven’t already, try Quincy. Good PR for them to see an oldie still in service.
Looks like a Quincy FA-4. The bottom left of first page in the .pdf I’m going to try to attach, fingers crossed.
I’m trying to identify this compressor. I need to replace the intake valve, and some gaskets.
It has a 3″ bore with a 4″ stroke. 16″ flywheel. Inside the aluminum breather cover was the only markings I could find, “130 130”.
Oddly enough, this is a DeVilbiss 130.
I AM TRYING TO IDENTIFY THIS INDUSTRIAL AIR COMPRESSOR PUMP THAT IS AT ONE OF OUR GAS COMPRESSOR STATIONS? I TRYING DRAW THEM IN 3D TO AS-BUILT THE SITE. WOULD YOU HAVE ANY IDEA WHAT MAKE AND MODEL THEY ARE? I DID NOT SEE ANY VENDOR TAGS ON THEM. ANY HELP WOULD BE APPRECIATED, THANK YOU, MIKE
These look like Ingersoll Rand 71T2 compressors. Definitey Ingersoll Rand but the model number is a bit of a guess since most 71T2s had 6 head bolts on the high pressure cylinder head. This may be an early version, since newer ones have fewer cooling fins. There are bolt for bolt knock offs made by other companies but I’m pretty sure these are genuine.
Actually, a 7T or 71T are the models with the fine pitch cooling fins.

THANKS ROGER THAT HELPS A LOT
Old 4-cyl 1-stg hand-portable:
I need help to identify this thing.
I can’t find any clear markings of manufacturer or date.
What I can see so far:
– 4 cylinder, single stage, splash oil lube
– Cast iron compressor and outlet diffuser(?)
– Walker-Turner motor (from dirt accumulation, possibly original)
– Well balanced hand-carry handle
– Stand-alone, no mounting or ports for a larger tank
– Appears to be a retail unit (ie. not a home rigged contraption)
– About the same overall size as the compressor/motor assembly
on my old Craftsman 6-gal (small) compressor unit.
Thanks,
Wayne
Turns out it’s a 1955 Craftsman paint sprayer 106.5592, made by Campbell-Hausfield
At the time, a mid-quality compressor for the application. But, still pretty interesting to me.
Looks a lot like a DeVilbiss paint sprayer, possibly licensed to a GB mfgr.
The hitch is four cylinder – DVs were usually single. Makes for smoother air flow…
Is it continuous run with valve unloader? Or can you tell?
Regarding continuous run with valve unloader, hmmm honestly I don’t know even know what that means %) I’ll read up on it and see.
BTW, here’s the 1955 catalog page. $108 back then was not exactly cheap.
Hi. Please can you help me identify my compressor, what year it is, where it was made and if and where I can get parts? It has a name on it but I can not find parts and I think it needs a small flat washer for one way valve on the inlet side as it is screaming
Thank you
Kirsty
I was recently given an old compressor. It worked but wouldnt shut off so i was going to buy replacement parts, but i couldnt find any ID markings on it, except for whats on the motor, and that hasnt gotten me anywhere. You can almost make out some letters and numbers from the original signage. It appears to have a Sears “S” but no other letters are legible. It looks similar to campbell hausfield older model. Ive tried jist about everything with no luck. Help would be appreciated
John, I just posted the same comp pump as you have in your pictures. I too thought it might be a Campbell Hausfeld, but cannot find that particular pump. The manuals are at this link Manuals/Parts List (campbellhausfeld.com) I’ve not searched the entire database, but have gone through about half, starting with the oldest.
Thank you Brian. Ill look into that. If it turns out to be a good thing ill be sure and let you know
Please identify or point me in the right direction. There are no identifying marks or plates on the compressor pump. The data plate on the motor is attached, but doesn’t help me (and looks as if it were stamped in a blinding snowstorm). The compressor runs, but needs a sight glass or dipstick. Need to know proper oil level.
Might be an old-style C-H vt6100 series.
Where would you put a sight glass or dipstick?
Oil goes up to the bottom of the threads in the case fill hole.
Thanks for the information Doug. Much appreciated. I’m going to pick up a 1/8NPT street tee and mount a tube style sight glass at a 45 deg angle via the drain. I have ordered one from McMaster Carr (US$26) rather than fabricating. I’ve taken a look and believe that I’ll still get sludge drainage when the drain plug is removed. If I remember, I’ll post a picture. I could also fabricate a dipstick using the 1/4 NPT fill plug and a 1/4 NPT MF fitting. This will be my backup plan if the sight glass shakes to death from the… Read more »
Interesting. Please post pix when you get it set up.
I have installed the sight glass. Miracles do happen. It works. On first try, oil seeped from the bleed at the top. I added a top hat. Now, the airflow is slowed enough to let air breather to do its work. The vibration is not nearly as bad as I thought it might be. The quality sight glass from McMaster Carr will last a long while.
Don’t you just love the look of polished brass?
Thanks for the update.
I would like get some info on this compressor.It is missing a fan on one end and it missing some little filters and of course the covers on both ends. A friend got it running says it works good just missing some things. Where would I go to find parts?
I’m having difficulty finding parts for my recently acquired Jacuzzi compressor too. In our quest for the holy grail, we may be talking to just about everyone in the business before we find what we’re looking for.
Happy hunting!

Happy hunting indeed! Of course, when (if) I find a resource I’ll certainly pass along the info.
Recently, I acquired this Jacuzzi Bros compressor and want to restore it to its former glory but can’t find any info, manuals or even parts for it. I don’t even know what model it is. Any help is much appreciated.
Hello all,
I’ve been given this air compressor recently and I would like to identify it and get a user manual for it before using it. I was told that it is a transair compressor but I can find nothing about it or even a similar one online.
Thanks
@Fas, pictures will help.
Small compressor about 15cm across. Pretty sure it’s from the 80s. Help appreciated.
Any idea if this is a compressor tank? What it was used for? And the value for it today, or if there is even a value? Thanks in advance
Hi all, just wondering if anyone can help me identify this industrial compressor do I am able to source parts, all help will be greatly appreciated.
There is no model or serial numbers anywhere only an M cast into side plate which I assume is a manufacturers brand ?
Cheers for any wisdom
This is a Gardner Denver. They tend to use a particularly impenetrable alphabet soup assortment of letters for their model designations, so I am unable to identify exactly which model it might be. Parts should still be readily available as GD is a top-flight industrial equipment company. They make all the locomotive compressors.
I think this may be a Reavell compressor. The cylinder head bolt arrangement and crankcase shape seems to suggest it. Water cooled Gardner Denvers don’t quite match.
I received this compressor from a local plant. I would like to rebuild it, but I can’t locate a manufacturer name if I need parts. The national boilers tag on the tank is dated 93′.
like to identify this compressor. sn/part # 14A7-2179 on block, 1001-B on head.
Hi John,
Please provide some photos
Thanks

Hi. I got this off a small homeowner compressor from 1968. Don’t remember if it was craftsman or devillbis as I scrapped the tank. Thanks You for your help
Any chance of some Pictures?
It’s a Hydrovane, that I have started to rebuild, brought at auction by a mate some years ago it was listed as a working compressor. is 3 phase which I will reduce to single phase. As to what possible model and year of make that is anyone’s guess.All images posted are all I have to try and identify it. Look for someone brighter than me who can help advise me as I try and rebuild this Hydrovane.

Ok everyone, thanks to Ashley I’m able to show exactly what I have here. Any help at all with finding out exactly what I have would be greatly appreciated. From what I understand thus far in researching the Hydrovane air compressors, it appears they are very quite in a workshop to work close to. As stated (1) it is three phase and as I only have single phase power I’m gunna have to change the motor. Whether that is possible I hope someone can tell me. (2) I hope to be able to use it for sand blasting jobs, not… Read more »
Hi Ken. I used to build quite a few Hydrovanes. They are very nice and very long lived machines. I believe yours is a series 5. They aren’t hard to overhaul, since mostly it entails replacing a few dozen o-rings and seals. There is usually very little wear inside a Hydrovane unless it has been run on improper oil that is too light or sludgy. If you want to do a full rebuild you really need a manual since trying to describe it would be almost impossible. If it were me, I would find the source of the oil leak,… Read more »
Thanks for your response Roger, I’ll certainly look into what you have provided me with. I did contact the company in UK that I found under the hydrovane section here, namely because a lot of stuff for years was imported from UK in Australia. I got an email response back, thanking me for my inquiry and it was suggested that to save money it maybe better to buy a new one rather than fix this one. I think the person responding failed to understand that it’s a rebuild project. If I really wanted a new one I wouldn’t be seeking… Read more »
G’day Everyone, well I’ve tried everything possible to make contact with compressorman.co.uk/ via his impressive web site, not sure if the Covid 19 has wrecked his business, but emails appear to go through as they haven’t been returned. As for telephoning haven’t tried that at this stage due to me bad stuttering problem. Have been hanging out on a response via email but as yet nothing. So I guess I just sit here keeping an eye on this posting in the hope that our world gets back to operating the way it use to. Regards Kev.
I just signed up to open an account with this business, got a response back saying they contact me shortly, maybe that’s the trick I hope, open an account with them. I really wanna see if I can get this compressor operational again.
Looking for any info/ manual/ parts etc. on this compressor aboard a motor boat. the compressor works okay, however, if and when it breaks down it would be good to have info and parts available especially while at sea!
The small front plate of the compressor has the numbers:

and 3-30 (or possibly 3-80) at the base
On the tank is:
Kargard Industries Inc., Marinette Wisc.,

This is a Quincy QR25 series pressure lubricated pump. The best you can get. The actual model is either a 308 or 310 by the look of it. If you can get the silver paint off of the tag under the dipstick it should tell you which. Do yourself a favor and take the pipe plug out of the cylinder head and screw in a 60psi safety relief valve. If it blows you know you have valve problems. It should be near indestructible if the oil level is kept up. You can get major overhau kits for these that you… Read more »
A complete set of assembled valves you can drop in would be a good idea to keep on hand. These are the likeliest source of trouble with high operating hours, especially if motor oil has been used in the compressor.
Thanks Roger! I was losing my mind trying to google different combinations of any of the numbers on the housing with no luck at all. Now if I could just get my hands on the person that painted over name plate.
Cheers!
1981 Cambell Hausfeld TF28? I thought that’s what I had identified it as until I called CH and the lady on the phone told me that’s not even a pump CH made. Other sources are telling me to replace it with a K30 pump. Confused. Need complete rebuild + replacement parts or better performing pump. All advice/help is greatly appreciated.
This is definitely a Campbell Hausfeld TF series. I believe it is a TF000021P, but that might be incorrect. What makes you think it needs a complete rebuild? I’d start by pulling the brass safety valve in the first picture and screwing in a pressure gauge and see what it reads. If it reads full tank pressure while running, you have bad HP valves. If it reads zero you have bad LP valves. If it reads a smooth 30-40psi, your valves are all good. If it’s not pumping a lot of oil or knocking, the pump is likely fine and… Read more »
I am very grateful you have taken your time to help me out. I had it apart to inspect it before running due to unknown history and attached were my findings and post cleaning results. Still less than desirable. After getting her running, initially my tank check valve was gummed up and not moving. After cleaning, I build pressure to 160psi (second stage cylinder wall looks fair), but at a calculated rate of 7.8cfm. The closest pump to it that I could identify (attached also) runs 17.3cfm free air. I have to believe this pump should be performing stronger. There… Read more »
Yeah. That block looks like it’s had the biscuit. All that moisture came in through the valve petals, so I am assuming the valve plate is pretty badly corroded as well. This will prevent them from sealing properly, which will definitely cause the second stage to carry the load. At that point you have a small bore single cylinder compressor, which is bad for both flow and pressure. I’m not surprised it’s running hot. If the bottom end checks out, I guess you could scour Ebay or some local compressor shops for a used block. Most likely the piston is… Read more »
Hello,
I am trying to identify this compressor pump we recovered from my Dad’s garage that burnt the other month. We installed it in 2006 as a replacement pump, but I don’t remember what brand it was, any help is appreciated!
This pump goes by many designations, but Sanborn SC23 is an easy one to find. It is actually built by LaPlante.
Thanks so much for your help!
I am trying to identify this compressor pump. The only numbers on it are 0288 14333. I am having issues with it keeping up. With just using an air grinder it will drop to 80psi and not recover if I continue to use the grinder.
Has it been able to keep up in the past?
It is new to me. I’m not sure of the actual output.
This is a Schultz pump. If it has been run without an air filter you can expect valve problems.
I’ve tried it with and without just to see if it made a difference. I will check out the valves. Hopefully I can get parts.
Well you were correct. Some broken springs in each head and a cracked valve. Any chance you can help me identify and find parts?
I believe you have an MSV-30 pump there. Might be an MSV40.
They have been around awhile so parts shouldn’t be too hard to track down. Contact Schulz America to see how to find out what you have. The cylinder bore and stroke will likely tell them which it is.
I believe Champion sold these for awhile on their budget machines. You may find companies have also built up house brands with these pumps. They are quite affordable.
After further investigation, I think this is an msv-20.
Hello,
Recently got this air compressor. Obviously the motor is aftermarket, and the plumbing seems to be “creative” but I’d like to identify the compressor. Thanks in advance.
Can’t tell you exactly what it is, but the plumbing is probably original. We’ve seen a few with this type of plumbing. The large diameter pipe is there to reduce the load on the motor during start-up.
Would more detailed photos of the compressor help in identification? It would be helpful to know should I need replacement parts in the future and to identify the pressure and CFM delivery.
More pix can’t hurt. Roger knows a lot of these old pumps, maybe he’ll chime in.
Most of these old pumps, you have to be “creative” about finding parts.
Does it run, pressurise and stop on its own? If so, you can time how long it takes to cut-off from an empty tank, calculate the volume of the tank, and get a ballpark of cfm.
I was able to peel back some of the paint layer and got this partial label from the tank. Is this familiar?
This is a very old Quincy A-4. Maybe pre-WWII.
Parts and more info here.
Thanks Roger! I work for Quincy’s parent company and was able to confirm through my resources that it is indeed a Quincy A4 ROC 6.
Regarding the plumbing on reciprocating units, why do I see so many with the corkscrew on the compressor outlet before the receiver and some without that corkscrew? What is the purpose of that instead of an “as straight and short as possible” feed?
This is to absorb vibration from the pump. Think of it like a spring. A short solid tube is far more prone to cracking. You will often see this on steam gauges as well.
…and thermal expansion/contraction stresses as well.
Hello, I need help identifying the name and function of the valves/solenoids attached to the heads of my Jacuzzi Brothers 331. I am getting air out of the intake and I believe it may be caused by the pin on these valves sticking down to far, not allowing the reed valve to close. Also, what is the function of the copper tube?
Thanks, Jim
I don’t know what pin you’re talking about.
The tube you marked out probably goes to an unloader at the end of the part you did not mark. If this is/was part of hot tub, then the unloader may just be a solenoid that closes when power is applied.
Doug, thanks for the reply. The pin is attached to each of the valves that are connected to each other with the small copper tubing. Solution above.
Jim
So, I was thinking about this over the weekend, and what made sense to me (as there is no power cutoff when the tank reaches pressure) was these 2 valves held open the intake reed valves when the tank reached pressure. I pulled the valves apart and found the one that was blowing air out the intake stuck in the open position. I cleaned, honed and replaced o-ring and the compressor now pumps and behaves as it should. Now I need to wire in a power cut off.
OK, so it’s continuous run with valve unloader, and you’re gonna make it start-stop with a pressure switch, yeah?
Good work with intake valves.
I have got this older compressor I just got it’s a Union Oil company located in Barstow ca. Any info would be greatly appreciated.
This is another E.L. Smith compressor
The seller of this pump assured me that it was working, and he seemed like an honest guy. Well he was only half right. The left side works, the right side doesn’t. So I took the head off the right side and guess what; Reed valves are all broken. Can the experts help me out and ID the make and model so can rebuild the heads? Thank you!

This is an E.L. Smith compressor. Contact American Eagle Compressors, They have the rights to the designs now. See if the V230 parts will work for you. They should be the same judging from the outside, but who knows what may have changed inside over the years. If they can’t help, google E.L. Smith parts and see who might sell repair parts.
I bought this worthington compressor from a old timer getting out of the farming business. I’m trying to find information on the model, what’s it’s worth, should I keep the 40 gallon (approx) tank. Compressor works well. I just took the compressor off the tank because I don’t have room for it anymore and it’s too far down my list of projects. If anyone can help me with info I would Appreciate it!!

Thanks ya’//
Trying to find out more about this seems like it should hold more than 100psi thinking maybe someone replaced parts on lower end of psi cause of not knowing how many gallons it is. Wanting to know how many gallons this is dose it really only hold 100psi? I need a replacement for that black valve.
The “gallons” is irrelevant to the pressure. You can measure the tank and plug the numbers into a “volume of a cylinder” calculator to get that. The pressure probably could be higher. There is probably a label or a stamped-in mark on the tank telling what the max TANK pressure is, but you don’t want the pump to go that high. Did the black valve break off or strip out? Just get the measure of the pipe size and you can use anything you find at a plumbing store. After you have that info, I’ll tell you how you can… Read more »
Ok thank you was just curious seemed like since it was bigger than my 3gal compressor witch is rated at 80 to 100 psi thought it might hold more.
And the black valve the previous owner had put a metal plug in one end and cracked the plastic then tryed to use a hose clamp over it too get a seal but it didnt work and leaks out pretty fast. Should i get a blow off valve too?
“Should i get a blow off valve too?”
Yes. Good call. I take it that plug is where the safety valve was.
If you found a rating on the tank, your safety should probably be 20-30 PSI less than that.
Awsome thank you havent had a chanve to get a new fit yet but was thing today i should do a oil chang what type of oil should i use? its 1hp motor
C-H says
Ok thank you. I found something saying i could use 10w-30 mobile 1 synthetic so is there any difference from it and actual aircompresser oil advantages and disadvantages?
Tricky.
There are those who say engine additives are bad for compressors, and I agree as it applies to “dino” oils. But as C-H notes, they don’t have a problem with it. You can get additive-free synthetic, if you’re so inclined.
Other than that, synthetic has it all over conventional, as it doesn’t break down nearly as fast; lasts two to three times as long. At least.
