Where can I find a seperator/filter for my speedaire dryer model 4xx33?

Duane, are you speaking of the:

Filter, Oil Removal

Item #: 4ZL18
Brand: SPEEDAIRE
Usually Ships: Ready to Ship
Price (ea): $336.50

If so, you can get this still from Grainger, though I suspect if you have the old one, you can visit a local fluid power shop, and get a comparably sized unit from them.

If this isn't what you are looking for, please comment here with more details.

Cheers,

Bill

Hi Bill, i have a Speedaire Model # 3Z529 Air Dryer and the automatic drain leaks air and cannot seal off. Do you know where i can find one? thanks.

(Please start a new thread and upload a couple of pictures of the existing auto drain. I expect I can find one, just cannot see exactly which one it is.)

water getting through Filter/Water seperator

by Paul
(Laurel, MD)

I have a Craftsman 4HP 25 gal compressor. 9.0 scfm at 40 PSI and 7.0 at 90 PSI. 125 psi max. The cheapo filter is allowing water thru the hose. Can you recommend a decent water seperator/filter?
Thanks

Paul, if in doubt about the quality of your air filter, then visit the local industrial supply shop that sells air valves, cylinders, and they will likely have FRL's too. They will be able to supply you with a good one.

However, compressed air filters are very simple devices, and I'm surprised that you are getting water into the air hose.... unless ...

~are you draining the compressor tank frequently enough?
~is the air filter installed correctly (arrow from high pressure side towards air hose
~are you draining the filter bowl often enough, or is the auto drain (if one)working
~how hot is the air coming from the compressor, and how long is the hose

I ask the latter because if you are using your air compressor a lot, and the air is quite hot, the filter will remove liquid, but it doesn't remove water vapor. If there is tons of water vapor in the air line, then it will condense there.

That being the case, put a filter just before you use the air.

Cheers,

Bill

Filter to remove water

by Rob
(Gallatin, TN 37066)

We have a large compressor that sits outside in an uninsulated shed and then is plumbed in through the rapidair alluminum pipeing, I am looking for a water removal system with 1 1/2 inch thread and will work with 175 psi?

Hi Rob:

I guess the first thing that you have to decide is how dry do you want your air?

If it is just the removal of free water from the lines, with no concern about water that may condense further down past the filter, then, any general purpose filter of the 1 1/2" pipe size will do. Most of the big manufacturers of compressed air components sell them through their distribution network, Norgren being one that comes to mind.

I recommend you read the pages about compressor water and the remedial guide there, to help you determine what your goals are, and the various technologies that you can use in drying your compressed air.

Cheers,

Bill

Air filter for compressor pump?

Curtis compressor - Alternatives for an air filter for compressor pump

I recently purchased a used compressor for my shop that was coated in 30 years of grease and grime. It was advertised as an IR and the air filter had IR on it also. After getting it home and cleaning it up I happily discovered it was actually a Curtis with a IR air filter assembly on it.

The air filter needed replacing and needing one quickly I searched the web for a good price and ended up purchasing one for $15 without a prefilter which I thought was fairly steep.

After I had everything up and running I took the time to measure and match the filter and found one that was correct in every way except 1/4" taller so I purchased it along with a prefilter and tried out it's fit which turned out to work and seal well around all edges. The IR filter #32170979 can be replaced by a Kohler #231847-S and prefilter #234869-S. Hope this helps someone.
