Air System Products RD11-VAC – Robo-Drain – 26″ Hg Vacuum System Drain

Air System Products RD11-VAC – Robo-Drain – 26″ Hg Vacuum System Drain

A fully automatic, zero loss drain for vacuum systems that requires no electricity. Translucent reservoir for visual assurance of operation. Vacuum to 26″ Hg.

How it Removes Condensate From Vacuum 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 close a pinch valve and balance line valve to isolate the drain from the vacuum system. Next air is directed to the drain valve actuator to open a full-port drain valve and to the drain reservoir to drive condensate from the reservoir.

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. At the same time, the pinch valve and balance line valves are opened and the drain is returned to the collection mode.
