Air System Products RD11-T – Robo-Drain – External Pneumatic Condensate Drain

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

A fully automatic, zero loss drain that protects compressed air systems with out the need for electricity. Translucent reservoir for visual assurance of operation. Ideal to be used along with Oil/Water Separators.

Demand drains use a sensor mechanism (a float ball connected to a level sensor) to detect when the condensate level has reached full capacity inside the drain before actuating the valve and releasing the condensate. That avoids any chance of the drain opening too often or not often enough, and also eliminates any air loss by leaving a residual amount of condensate inside the reservoir when it actuates to prevent any air escaping.

Operates on demand 

How it Removes Condensate From Compressed Air Systems

Condensate enters the drain through one of two inlet connections. As condensate is collected and the translucent reservoir fills, a stainless steel float mechanism rises. When the condensate reaches a design level, the float mechanism actuates an isolated magnetic trigger assembly. The trigger assembly directs control air to the valve actuator, which in turn opens a full-port drain valve.

Condensate will then exit the unit. As the float drops, the trigger assembly closes the control air line and the valve actuator closes the ball valve. The drain is then returned to the collection mode.
