Whole House Ventilator
A whole house ventilator supplies fresh air to a house, correcting poor indoor air quality, excessive condensation and negative air pressure. This system mixes cold outside air with warmed house air before introducing it to the house and provides needed fresh air to the entire house and all appliances.
The Draw Collar keeps the flue or liner warm so there is never a cold downdraft. This can be added to the flue collar of any wood stove insert, freestanding wood stove, and in some cases, Direct Vent gas fireplaces. This may the the only solution to a smoking wood stove on the lower level of a home because negative house pressure on the lower levels may not be able to be corrected.
The Condar ASV is made of tough ABS polymer. Outside air enters the ventilator through a louvered grill, which provides protection from rain. Insects and vermin are excluded by a separate screen located directly behind the grill.
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.
