New husky 2 gallon air compressor ... now what?

by pd

I just received the husky 2 gallon air compressor from Home Depot as a present. What is the max this thing can do, what tools will work well?

Good day, PD.

Two gallons is the tank size, and although this tells me that this is a small air compressor, it does not provide details about the pressure and flow capacity.

The flow or output of your compressor should be around 3-4 CFM of compressed air at 90 PSI for every horsepower of electric motor size. I suspect that your is low HP, so you can't expect much flow out of it.

Your compressor will have a pressure rating, and I would think you will see 100-125 PSI at cut out pressure level in the tank when the compressor is filling.

With this level of pressure, you have the power to run any air tool.

What you lack is the output air flow at that pressure.

So, if you have a tool that demands 10 CFM of air at 90 PSI, you would theoretically need an air compressor with a 2.5 HP motor on it to provide that flow.

On the other hand, you can inflate tires, footballs, and use any air tool that demands low flow, like a brad nailer for instance. You pull the trigger on the gun, it fires, uses a small amount of compressed air, and then it uses no more air until you pull the trigger again. Pull the trigger really quickly and your compressor will struggle to keep up. Trigger it every few seconds as you position the workpiece, and that little compressor will work just fine.

While it has the power to drive a wrench, drill, grinder and so on, it will not have the flow, and won't be able to generate the flow, necessary for this type of high demand air tool.

Cheers,

Bill

we bought 155psi 1.8hp. 20gals. does a air dryer needed?

Sorry, but that's one of the questions that leads to many more before a clear answer can be formulated.

What's the on-time of your compressor? What is the compressed air being used for? Does the air appliance need a special level of dry air?

I suggest you read the pages linked to Compressor Water, as they will provide much information about just what is necessary to dry your air to your system needs.

Cheers,

Bill

HUSKY H1820F compressor tank pressure

by Anthony Lee
(Pt. Hueneme, Ca.)

I have a HUSKY H1820F compressor. My tank pressure gauge reads 60psi. It gets no higher. My pressure gauge goes up the required MAX of 155psi cut out Min 125 cut in. Should my tank pressure gauge register higher?

Howdy Anthony. What I hear you saying is that your compressor keeps running, but the pressure in the tank doesn't get past 60 PSI. Is that correct? If so, that's not at all uncommon, and suggests that you have one of a few problems.

Take a look at the Troubleshooting page, and click the link to the pages that discuss "why my compressor will not build pressure". After a read of those, if you have any more questions, please post a comment to this thread.

Bill

regulator only hold 120 and up pressure on Husky air compressor

by Al

I have a Husky 5 hp horizontal compressor 8CF for the last 6 yrs and it has worked fine.

Lately I could not regulate the pressure below 120 psi.

I mean if I put down the regulator less than that pressure you will hear how the pressure leak and gets out.

I thought to add another one in the line, but as I added a filter I have no much room.

When new you could control the pressure for applications that require for instance only 30 psi, etc. So I thought that it was the regulator and I bought another new one at Home Depot and installed it.

It does the same. If I go down it leaks, and if I quickly move up over 120psi, it stay good, but it will restart frequently + providing more pressure for the application I need.

What the problem then?

Thank you,
Appreciated.

When your compressor fills with air to the cut out pressure level, is that level 120 PSI?

From what you are writing it sounds as though when you dial down the air below the 120 PSI level, that the regulator is bleeding off the downstream air that is higher than the new, lower pressure level, and it is supposed to.

So, please dial the pressure down to 30 PSI, let the air bleed off, and it should stop bleeding off after a few seconds, depending on how much air you have in the lines downstream from the regulator.

Does this help?

Cheers,

Bill

working fine
by: Anonymous

Finally i replaced the regulator and added a much better water-drain valve.

The almost 9 yr Husky horizontal compressor is now working as new, keeping its 130 pressure at the beginning and in general all with no complaint for its kind.

However too little for other plans i want to make them come true. It means i will need a big one at some point when my wallet allows me to have it, and i know i will not regret it.

Thanks Bill.

i'll keep trying
by: Anonymous

Yes Bill i know i will need 220v.

I have a small woodworking shop at home (installed 220 there recently), and i just can't afford now that big boy, but i do the mechanic of my car as well, and i am planing to pain it myself in the future, so i will need the big one.

I'll try again tomorrow and probable i need a good regulator not that cheap thing they used to make today and usually comes from China.

Sorry if there is a chinesse around. No hard feelings or anything personal, but it is true.

Best regards.

same
by: Al

Same, when dial down the air below the 120 PSI level, the regulator begins bleeding off, it cannot regulate less pressure. It is a new regulator from Husky. The old one used to do the same.

Maybe there is something else?

Everything is tie on with teflon, etc. So i can't understand. These small compressors are allways a noisy headache.

Hope one of these days i can affort to buy a 2 cicle big 80g no less 14 cf compressor.


______________________
Al, you will need 220 power for that big boy, when you get to buy one.

I still need to know, when you dial the pressure down on the regulator, are you saying that the needle won't drop past 120 PSI, and air continuously bleeds?

If that is the case, let it bleed down to zero and watch the regulator gauge. The needle should follow the pressure down.

If it doesn't you've got something wrong with your regulator I think.

Cheers,

Bill

It will go a little bit more, like 140 psi, but if I dial counterwise downfrom 120, it is when the leak begins. It holds all the air while you regulate over 120psi. Recently I gave the compressor a good maintenance.

I will try what you said tomorrow and see if it goes less than 30 after.

Thank you.
Al.

Al, depending on what you did during your "good maintenance", if that included removing and replacing your regulator, make sure it's installed with the air flow going in the right direction. Look for an arrow.

husky 80 gallon 7 hp crank case get pressure blows the oil fill plug out

by dave johnson
(madison indiana )

i have a husky 80 gallon 7 hp two stage my crank case blows the oil fill plug out, i have tested the rings with air and no leak down, could it be the reed valves are backward from the factory, man i am at a loss.

Check to make sure that the crankcase oil fill plug has it's vent hole open (not blocked).

Or, if the piston rings are OK, you may have a gasket failure leaking air to the sump.

Find out what it was?
by: john

Did you ever figure it out? Mine is doing the same thing!
I can feel pressure in the oil tube even when
turning the flywheel by hand

_______________
I would suspect that the piston seals are going.

Husky 5hp compressor motor runs hot on 110 Volts

by brandon
(flint, mi)

I have a husky 60gal 5hp air compressor. The specs given for wiring are 240v 30amp. The guy i got it from had it wired for 110v. now when i hook it to my 220v outlet the motor gets hot and trips the breaker. Is there something wrong with the motor now it still runs on 110v but seems weaker than it should.

____________________
Bill says...

If he changed the motor to a 110 Volt unit, then you will burn the motor out, I would expect.

If it is the original motor, then it must be dual voltage, and it is how it is wired that is the issue.

I regret I am not an electrician and cannot provide electrical advice. Talk to your local electric motor rebuild shop as to the differences in wiring up a dual voltage motor.

Cheers,

Bill
