As Condensate Collects in the Air Receiver, It Will Drain Into the AFD-50 Tank Drain, Flow Beside the Vent Tube and Accumulate In the Drain Reservoir. The Liquid Will Rise and Begin to Float the Ball and Force Air Out Through the Tube and Into the Receiver. Rising Liquid Level Will Cause the Float to Open the Discharge Valve, Expelling the Liquid. As the Float Returns to the Low Position the Valve Closes and the Cycle is Repeated. Each AFD-50 is Equipped with An “ Anti Air Lock ” Vent Tube Which Prevents Loss of Compressed Air.
