Great protection for air tools

I love the inline water separator for using my compressor in the colder months! I can already see condensation in the filter!

Works great

I have a ton of moisture from compressor (separate issue) and this filter does the job extremely well.My only nit-picky complaint would be the sticker in the center of unit is difficult to remove and leaves a residue behind. With gasoline cleaned off easy though. This has no impact on functionality, just throwing it out there.Highly recommend.

Passes more water through than it collects

Seemed to pass more water through than it collected. I used a needle scaler for hours. My hands were soaked the whole time. The product never filled up a quarter of the way.

Does what it is supposed to. It keeps my sandblaster from clogging. Works well so far
