Electronic Timer Condensate Drain Valve for Air Compressors, Receivers and Dryers, 1/2 in, 220 V AC

An electronic timer drain for the condensate that collects in compressor receivers, dryers, separators and filter bowls. A brass solenoid valve opens for a set time at a set interval and blows the water out, so it never builds up and gets carried into the air lines or soaked into new filter elements.

The timer has two dials: open time from 0.5 to 10 seconds and interval from 0.5 to 45 minutes. A TEST button opens the valve on demand, and the brass strainer body with a manual ball valve lets you isolate and clean it without draining the tank. 1/2 in BSP male inlet, 220 to 230 V AC coil, rated to 16 bar.

Technical properties & sizes

Applications & use cases

Replacing a failed float drain
Float drains stick with oil and rust and let water past. A timer drain has no float to stick and opens on schedule whatever the condition of the condensate.

Air receivers
A tank that is never drained fills with water, loses capacity and rusts from the inside. Set the interval to suit the duty: a few seconds every 10 to 20 minutes is typical for a workshop receiver.

Protecting new filter elements
Water carried past a full bowl soaks coalescing and particulate elements and shortens their life. Draining the separator ahead of the filters keeps them dry.

Dryers and aftercoolers
Refrigerated dryers separate a lot of water. A timer drain on the dryer outlet trap keeps it from flooding back into the air.
