The OPTIMUM timer controlled condensate drain is suitable for a wide range of compressed air applications including compressors, receivers, filters and refrigerated air dryers.

With an easily adjustable electronic timer, a direct acting solenoid valve, a large orifice and options for a brass or stainless steel body, this drain provides reliable compact condensate removal.

The OPTIMUM is easy to install, simple to adjust and rated for pressures up to 230 PSI. It includes a test switch, LED on/off indication and a serviceable valve. Most importantly, the large 4.5 mm orifice means it is perfect for difficult applications with high condensate flow rates and solid particulate contaminants.

The 115VAC version of this drain is supplied with a 6 ft. power cord with plug and the 230VAC version is supplied with a 7 ft. power cord.
