Review on Compressor Filter Separator Lematec AI 303 by Ham Channell

This dehumidifier has lasted about two years with moderate use. I'm a hobbyist and have used this on my 20 gallon compressor tank when using air guns, a stapler and light HVLP spray. This morning after spraying at 20psi yesterday (about 15 minutes) I heard a slight hiss when plugged in. I thought maybe the connector (of the plug separator) needs to be resealed with teflon. However, it turned out that the hissing came from air leaks under the gland of the drain valve (not the valve itself, but at the point of attachment to the body of the device). I'm not sure how long this stuff is supposed to last, but I'm just updating to let the public know about my experience with it. In this volume I buy the NEIKO brand and see how long it lasts.
