Field Controls Round Air Booster Fan

The Field Controls Round Air Booster Fan (also called a duct booster fan or inline duct fan) improves the flow and distribution of heated and cooled air to "problem" rooms in homes and light commercial buildings. It mounts in the ductwork of a branch run. It helps reduce hot and cold spots in rooms far from the main air handler.

Key Features:

• Mounts inside round metal or flexible ductwork to boost air delivery through restricted or long branch runs
• Heavy-duty 120V, 60 Hz motor built for long, trouble-free operation
• Runs at 3000 RPM
• Suits both forced-air heating and central air conditioning systems
• Can be wired in parallel with the furnace blower, so it runs only when the main system is moving air
• Helps improve heating and cooling system efficiency and saves energy
• Straightforward installation. Field Controls provides an installation manual for the AB-6 and AB-8 boosters.

This line is made for HVAC branch duct air boosting. It is not intended for clothes dryer venting. Field Controls has a long record of making HVAC air-quality and venting products, and this line comes from that background. Each model is matched to a different round duct size and airflow capacity.
