Description

RD11-T Robo-Drain – External Pneumatic Condensate Drain for Compressed Air Systems

The RD11-T Robo-Drain is a fully automatic, zero-loss condensate drain engineered to protect compressed air systems without the need for electricity. Its translucent reservoir provides quick visual confirmation of operation, ensuring your system is free from excess condensate. The RD11-T Robo-Drain is ideal for use alongside oil/water separators to maintain compliance, prevent damage, and ensure system efficiency.

• No electricity required, reducing installation complexity

How the RD11-T Robo-Drain Works

Condensate enters through one of two inlets. As the translucent reservoir fills, a stainless steel float mechanism rises to a preset level, triggering the magnetic trigger assembly. This directs control air to the valve actuator, opening the full-port drain valve to discharge condensate. When the reservoir empties, the float drops, closing the air line and sealing the ball valve, returning the unit to collection mode.

Construction Materials
