California Air Tools EZ-1-2321 Automatic Drain Valve, Black

Hooked it up to my compressor and away it went, works great and removes condensation at bottom of the tank, easy hook-up

Works great draining compressor

Works great once hooked up, however, it did not come with the parts needed to hook up to the compressor as shown in the video. You will need an elbow and straight or flex 1/4" pipe to hook unit up to the tank, and then a 1/4" to airline tube stepdown along with flex tubing if desired on the output side.

Works as described. Programmable. In combination with after dryer and float drain in line works better than refrigerant dryer I had previously

Works great. Make sure tank is clean or add a screen before this, had it lock open with rust when I first installed it on an older tank.

Our compressor came with one of these on it. It froze up after 10 years of service snd I just disassembled, cleaned and rebuilt it and it works like new. Took 10 mins. Well built.

Works great. Also relieves stress of always forgetting to drain the tank. Simple to hook up.

How it works is NOT the way described in the video. 1) Rather than running for every X minutes the compressor is running, it runs every X minutes the VALVE (separate power cord) is powered up. So if you switch the compressor power switch to turn it off, the valve will still open every X (I used 20) min for Y (I is used 2) sec. 2) Did you notice the compressor in their video is tilted? There is a reason, I have -exactly- that model compressor and the valve body, using the closest fit 1/4 NPT nipple I could find, still sticks below the feet and wheels. Yup, even with the leg bolts extended as far as I could, the compressor still high centered on the valve. I had to add some 2x4 blocking under the feet and wheels to give enough clearance. 3) Remember them talking about the outlet and it having an 8MM compression fitting outlet and them including a 8mm hose? Well the one I got didn't. It has a 1/4 NPT female port , no fitting and no hose. I mean it works. I just had to "make it work" rather than plug and play.
