Field Controls 46119402 Air Booster

The Field Controls 46119402 (Model AB-6) is a heavy-duty 6-inch duct booster fan engineered to resolve persistent airflow imbalances in residential and light commercial HVAC systems. Operating at 120Vac and 3000 RPM, this unit effectively boosts HVAC airflow by moving up to 225 CFM of conditioned air through standard 120mm or 6-inch round branch ducts. Designed for professionals seeking a reliable inline duct fan solution, the AB-6 is specifically for installation in branch runs to eliminate "hot or cold spots" in rooms furthest from the primary air handler.

This ducted air booster features a thermally protected motor capable of handling air temperatures up to 180°F, making it suitable for both forced air heating and central air conditioning systems. For optimal HVAC system efficiency, the AB-6 is typically wired in parallel with the furnace blower, ensuring it activates only when the main system is moving air. Its compact 7-1/2 inch length allows for seamless integration into 6-inch round ductwork or flexible ducting without significant modifications to the existing layout.

• Enhanced Air Distribution: Delivers up to 225 CFM to increase the delivery of heated or cooled air through restricted or long branch runs.
• Durable Construction: Features a high-speed 3000 RPM motor with thermal impedance protection for stable performance in high-temperature environments.
• Versatile Compatibility: Engineered for use in 6" round metal or flexible ducts, perfect for retrofitting older HVAC systems.
• Simplified Integration: Designed for parallel wiring with the primary blower motor or manual control via a standard on/off switch.

Can I use the AB-6 as a primary exhaust fan for a dryer?
No, this unit is designed strictly for HVAC branch duct air boosting and is not rated for clothes dryer venting due to lint accumulation risks.

Is this air booster compatible with vertical duct runs?
The AB-6 is specifically recommended for horizontal duct installations to ensure motor longevity and proper airflow dynamics.

Does the unit require a separate junction box?
Yes, the technician must provide a standard electrical junction box for secure field wiring and strain relief.
