How it Removes Condensate From Compressed Air Systems

Condensate enters the drain through one of two inlet connections. A stainless steel float is attached to a lever arm. Attached to the other side of the lever arm is a filter protected poppet assembly. 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 a poppet assembly. The poppet assembly directs control air to the valve actuator, which in turn opens a full-port drain valve.

Condensation will then exit the unit. As the float drops and the poppet seal closes the control air line and the valve actuator closes the ball valve. The drain is now ready to accept condensate again.
