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.
