Air Supply Ventilator (ASV-90). Fresh Air Supply is made of tough ABS polymer. Outside air enters the ventilator through a louvered grill, which provides protection from rain. Air flows into your house through a tube inside the ASV that can be cut to fit any wall thickness up to 14 inches. A manually-operated damper controls the airflow, with settings ranging from fully closed to fully open, or any volume flow in between. If desired, you can dictate a constant minimum airflow by popping out an optional plug built into the damper. Air passes through a filter before entering the room. The ASV's filter captures dust and is removable for cleaning. The filter also helps block outside noise. If you suffer from asthma or seasonal allergies, optional filters are available from the Condar Company that remove pollens and other very fine particulates from the air before it enters your home. The ASV comes complete with hardware and caulking for installation. PURCHASE DIRECT FROM THE MANUFACTURER!
