Auto Viscous Filter

AFi's Auto Viscous filter is a self cleaning viscous filter using a rotating curtain of metal panels as the filtering mat. Behind the filter mat is an endless roll of oil drop eliminator. A timer controlled, totally enclosed thermally protected geared motor rotates the filter media & oil drop eliminator which pass through a viscous oil bath located at the bottom of the filter. The viscous oil cleans the filter media & the oil eliminator minimizes the carry over oil droplets into the air stream. The sludge collected in the oil bath needs to be cleaned periodically.
