American Aldes Ventergy Series® DSVS Distributing Supply Ventilators provide fresh air to bedrooms and living areas. Outside air is filtered and distributed to two-to-four spaces. Optional passive airflow control regulators (CAR Classics) can be installed in the supply duct. These devices automatically adjust to pressure fluctuations in the system, ensuring precise air volumes. The DSVS prevents unwanted infiltration through the building envelope and creates a positive-pressure situation that reduces the risk of backdrafts from heating appliances, water heaters, and fireplaces. The DSVS is an optimal solution for homes without central forced-air heating or cooling systems.

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-DSVS Distributing Supply Ventilator Kit. Each supply air duct take-off can be fitted with an automatic self-balancing constant airflow regulator (CAR Classic) that ensures precise flow rates, independent of duct lengths. The passive control element in each duct run inflates or deflates automatically in response to system pressure to maintain specified airflow rates. CAR Classics are sold separately or provided with kits. Note: Certified performance ratings do not account for the effects of accessories or optional balancing dampers.
