The system consists of twin towers filled with desiccant of appropriate quality and quantity. Wet compressed air after being filtered by the prefilter and coalescing oil filter enters the distribution valve. An electrically operated valve with built in passages, which directs the air to one tower. The air is then passed through the tower and comes out in dry condition. The air is then passed through after filter to remove any carry over dust, via non-return valve. There is a by-pass arrangement with an orifice, to allow a fraction of dry compressed air to expand and pass through the other tower, here by regenerating it and making it ready for adsorption Cycle. The Regenerating air is passed out to the Atmosphere via muffler. At a preset time, the sequence control timer actuates the Distributor valve to reverse the tower function .
