Automatic Electronic Timed Drain Valve for Air Compressor, 1/2" Brass, DN15, AC110V

The media could not be loaded. I wish I would have installed an automatic drain years ago. This thing is simple and super effective way of keeping built up water and oil OUT of your lines and tools. Phenomenal .

Does not work properly. Items bypasses a small amount of air through the drain at times, leaks air severely from the shut off valve made into the drain inlet, and the unit does not drain air while “ON”. Instead, it drains air at random times. I will go buy one from McMaster Carr like I should have in the first place.Refund please.

Works fine at low pressure (20-50) psi, but as soon as you get up above that it starts buzzing very loudly.
