American Aldes Ventergy® Series BVS Blending/Filtering Ventilators are great solutions for bringing fresh air into tightly constructed homes. As outside air enters the ENERGY STAR rated BVS120 or 200, it mixes with return air from up to five bedrooms or other areas that are typically not served by a central thermostat. The resulting tempered air passes through a filter before being distributed to living areas. The BVS is an efficient way to enhance thermal comfort. By slightly pressurizing the structure, the BVS prevents the introduction of contaminants and reduces the risk of backdrafting heating appliances, water heaters, and fireplaces. Optional Constant Airflow Regulators (CAR-II) accurately balance the amount of air so the home meets ASHRAE 62.2 requirements.

Accessories are available to accommodate applications ranging from single-bedroom apartments to five-bedroom houses. Accessories are included only when ordered as a Ventergy® Series IAQ-BVS Blending/Filtering Ventilator Kit. Each return and fresh air duct take-off can accommodate an automatic self-balancing constant airflow regulator (CAR-II) that ensures precise flow rates at each point, independent of duct lengths. A passive control element in each duct run adjusts automatically in response to system pressure to maintain specified airflow rates. CAR-II sold separately or provided with kits. Note: Certified performance ratings do not account for the effects of accessories or optional balancing dampers.
