Condensate starts filling inside the drain valve. Air locked inside the drain valve is released through Breathe-out port. As the condensate level raises up, the Magnetic float (1) moves up and triggers the reed switch.Controller (2) receives the signal from reed switch and energize the Solenoid valve (3) for a short duration. Thus, collected condensate is drained out. Solid particles are retained over the surface of Strainer (4).
