Description
Robo-Drain RD750
External Pneumatic Operated High-Pressure Condensate Drain
A fully automatic, zero loss drain that protects compressed air systems with out the need for A fully automatic, High Pressure, zero loss drain that requires no electricity. Stainless Steel vessel for 750 PSIG design. Ideal for Oil/Water Separators.
The Robo-Drain is designed for trouble-free operation. When installed and operated properly, the Robo-Drain will provide years of reliable service collecting and discharging condensate, along with pipe scale and other contaminants typically found in a compressed air system.
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.
