Robo Automatic Condensate Drain RD750

External Pneumatic Operated High Pressure Condensate Drain

The Robo Drain RD750 is the ultimate high-pressure, fully automatic zero loss condensate drain. Its design allows for it to fit into tight spots and it handles scale and rust without clogging. A unique air valve design uses magnetic force to ensure both a positive opening and closing that prevents any compressed air loss.

The magnetic force is cleverly positioned away from the condensation level to prevent any attraction of metal particulate. An innovative ball valve support and positioning system prevents the side loading problem which otherwise would cause premature sealing failure around the valve stem.

How It Works

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.
