Works very well, just as advertised. I wish it could be set to blow off a bit less often. 45 minutes is the shortest intervals you can set it. That's probably good for a commercial operation, but if my 80 gallon blew of every 1 1/2 to 2 hours, I'm sure it would be fine. I've only had it hooked up for a week, but so far so good.
Buy New Electronic Auotmatic Tank Drain for Air Compressors Now
Since I never seem to remember to drain the air compressor tank, this product looked like the answer. Out of the box it was obviously very well made and was also easy to install with the addition of a 3/4" to 1/2" NPT reducer. I have it set for a 2 second burst every 30 minutes and it appears to be working well but I may have to reset it in the summer when the air is more humid. Overall great a great product for a fair price.

If you have a compressor that you use regularly and keep full you need one of these. Solidly built and simple to install. You supply the pipe and fittings to go from the compressor to this drain. Meaning you might need a section of pipe to go from your drain valve to this drain. Typically drains are 1/4" NPT and this unit has 1/4 inch female NPT on both sides and 1/2 inch NPT. Connect this to a drain line that runs outside or into a floor drain. You can slip a piece of garden hose over the one end and put a hose clamp on it to accomplish this. The black control box can also swivel to be turned to face a different direction. The directions are not great but if you can handle basic plumbing and have some pipe tape you'll do fine. The longest cycle time built in is 15 minutes, and you can adjust how long the valve stays open as well up to about 5 seconds. I put it on an outlet timer. So it only cycles about every 12 hours. As soon as you plug it in it cycles. So just put a plug in timer on the outlet to kick on for a few minutes how ever many times a day you want. Mine drains twice a day and that takes care of it just fine. If it's just a home weekend shop you could probably set it to drain just a couple times on weekends with the right timer. It does have a three prong plug so get the right timer if you do this. You can also still manually drain the tank and this valve also works like cleaner for the small screen strainer that prevents rust and sediment from in the tank from getting into the valve.

I just received and installed this valve on an 80gal, vertical tank compressor. It appears to be very well made, all brass and stainless steel valve materials. Of course the electronics are in plastic, but every thing seems very sturdy. This valve is an excellent value for the price, most automatic drain valves cost much more. I had been wanting to add an auto drain to my compressor for some time, but didn't because of the prices. When I found this on Amazon I was skeptical of the quality because of the low price. After receiving it and seeing how well it is made, I am very pleased. Since I just installed it, I can't report on how well it holds up, but I can see no reason it wouldn't.
