Thread: Where can I get a high quality water/air filter?

Tweet

This is for my air compressor. I have upgraded all my lines and connections to 3/8" ID and 1/2" fittings. I cannot find anything better than 1/4 filters at home depot and loews. The filters from Harbor freight with 1/2" inlet/outlet seem to flow too low. I figured some one with better knowledge could point me in the right direction. I am not looking for the cheapest filter and dont mind paying for something a little bigger to give more air flow. Thanks

I got the blue HF filter, it's the industrial quality 1 and it's great, I paid $25 for it I belive. flows just fine. http://www.harborfreight.com/cpi/cta...temnumber=1118 I'v painted with it.

Yes I seen that one at Harbor freight . I took it apart to inspect it and found that there is a bolt blocking the passage where the elbow is connected to. The fitting is like 1/2" inch but inside where the bolt is you only have less than 1/8" passage on either side of the bolt. This did'nt look right to me ,dont know maybe I am missing something? My biggest concern is getting sufficient air flow to my plasma cutter.






Heres what I got Rating 3.2
SCFM @ 40 psi
10.2 @ 90 psi
135 psi max 60 gallon tank

Part number is VT631402AJ

Thanks for any help. I will be running shop tools and a Plasma cutter.

it flows pretty well. the fitting the elbow connects to is 3/8", behind it there is the big retaining bolt that holds both caps on, but it is far enough back from the fitting, and the center of the bolt is polished to a mirror finish ( probably stainless too ). it flows good. tonight, I'll go out and dig out the instructions, see if it has CFM ratings, I think it does. your compressor ratings are backwards, you would have more CFM @ 40 PSI than @ 90 PSI.

What do you think about two filters in parallel?

is this for the compressor in your truck? (suspension) or shop?

I use a dessicant filter that I bought at a military surplus auction, no idea who makes it...Works great. I think Sharp or DeVilbiss offers a good one. As for your plasma arc, the flow requirements for light duty hot rod type work are low enough that even a Harbor Freight cheapie should be adequate.... I would consider spending some $$$$ and getting a good one, you're going to need it eventually. Easy and cheap way to lessen the amount of water in your system is to put a 3' or 4' U shaped loop in the line with a drain valve at the bottom of the U....

These are some of the Bendix products we use

with my seperator, the 1/2" line feeding it, goes into a 90* bend all the way up to the celing, then back down, almost leval with the work bench ( just enough space between it and the work bench, to open drain ), my compressor makes a lot of water, but I never have got water out of the seperator.

Yup, just a simple old water trap does a heck of a good job of limiting the moisture. That and draining the compressor every day will help ensure it and your air tools have a long life....
