HEATLESS TYPE AIR DRYER HOW IT WORKS The contaminated compressed air is made to pass thru Prefilter PF (for removal of solids & liquids) and Oil Removal Filter ORF (for removal of oil vapour) before entering Tower A1 thru a 3-way valve where it is dried by the adsorbent. Dry air exits the Dryer thru the After filter AF (where fine particles, if any are trapped) for use. A part (10 - 15%) of the dry air is expanded in the Purge Control Valve (PCV), passed thru Tower A2 to regenerate the adsorbent and exhausted out of its Purge Exhaust Valve (PEV) thru a Silencer (S).
