Description
The Field Controls 46119402 Round Duct Air Booster 6″ 225 CFM AB-6 increases airflow movement through runs by using an inline motorised fan to push air toward distant outlets. It operates through an electric motor-driven impeller that accelerates air velocity inside round sections, responding to power input from the connected circuit. It is positioned within ductwork between supply trunk lines and branch outlets in residential or light commercial air distribution layouts. The unit improves air delivery to low-flow, balances temperature variation across zones, and maintains more uniform circulation through extended duct networks in HVAC systems.
