Spectra Auto Viscous filter is a self cleaning viscous air filter using a rotating curtain of metal screen as the filtering media. Behind the filter media roll is an endless roll of oil drop eliminator. When the filter media is loaded and the pressure drop increases, a totally enclosed thermally protected geared motor moves the filter media and oil drop eliminator which passes through a viscous oil bath located at the bottom of the filter. The viscous oil cleans the filter media and the oil drop eliminator ensures that the oil is not carried into the air stream. The sludge collected in the oil bath needs to be cleaned periodically.
