Description
Dehydra
External Pneumatic Condensate / Moisture Drain for air compressors
A fully automatic, zero loss drain for vacuum systems that requires no electricity. Translucent reservoir for visual assurance of operation. Vacuum to 26″ Hg.
The Robo-Vac is designed for trouble-free operation. When installed and operated properly, the Robo-Vac will provide years of reliable service collecting and discharging condensate, along with pipe scale and other contaminants typically found in vacuum systems.
How it Removes Condensate From Compressed Air Systems
Condensate enters the drain through one of two inlet connections. A non-metallic float is tethered to a float arm. As condensate is collected and the translucent reservoir fills, the float rises. When the condensate reaches a design level, the float lifts the trigger assembly and a drain cycle is initiated. The trigger assembly opens and directs control air to the valve actuator, which in turn opens the full-port drain valve.
Condensate will then exit the unit. As the condensate level drops, the trigger assembly closes and the valve actuator closes the drain valve. The drain is returned to a standby condition.
