Aldes Ventergy® Series FSVS Filtering Supply Air Ventilators are designed to provide precise amounts of outdoor air to the occupied space. Fresh air passes through a filter before being distributed, either via the supply stream of a forced-air unit, or through an overhead return in the main living area. The low-volume fresh air provided by the FSVS140 keeps indoor air quality high, and the space stays positively pressurized to avoid backdrafts and unwanted infiltration.

Accessories are available to accommodate applications ranging from single-bedroom apartments to five-bedroom houses.
