A pollution control system includes a condenser and filtering unit for removing vaporized organic solvents and particulate matter. The condenser includes baffles that define vertical flow paths, and hot exhaust gases are directed from above to alternate flow paths to flow downward while atmospheric air is directed upwardly through the remaining flow paths to cool the exhaust gases and the heated air is used to maintain the atmospheric air above a selected temperature. The filter unit includes a horizontal movable filter which is automatically replaced with a new filter section when the pressure differential across the filter exceeds a certain level.

A method of removing contaminants in a vaporized phase from heated exhaust gases comprising the steps of moving the exhaust gases downwardly in a heat exchanger while flowing air upward in said heat exchanger to cool said exhaust gases to a preset temperature and condense said contaminants from the vaporized phase to a liquid phase while some of the condensed contaminants are collected in a lower portion of the heat exchanger, drawing said exhaust gases downwardly through a filter section with a fan to further remove condensed contaminants from said exhaust gases which are now changed from gas phase to an aerosol liquid particulate form, and introducing a movable charcoal filter across said exhaust gases downstream of said fan to remove odors from said gases.
