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 psig*. It includes a test switch, LED on/off indication and a fully 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.

Perfect for installations with:

• High condensate flow rates

• Particulate contamination

• Corrosive environments

• Pressures up to 300 psig

• Steady condensate loads
