Airflow Control HVAC Air Dispersion

Airflow control is critical in HVAC air dispersion. The zip-in Adjustable Flow Device (AFD) offers variable resistance to balance static regain, balance airflow to branches, reduce turbulence, and reduce abrupt start-ups. The patented AFD is a polyester mesh cone with a factory set or field adjustable hemmed drawstring aperture for air balancing DuctSox Fabric Ductwork Systems. AFD devices come standard with Sedona-Xm and TufTex Systems. It is also an option with other fabrics.Airflow control is critical in HVAC air dispersion.
