Field Controls 46065401 Air Booster

The Field Controls 46065401 AB-2 Air Booster is a high-performance solution for residential and light commercial HVAC systems, specifically engineered to eliminate temperature imbalances in problematic rooms. This 120V duct booster fan is capable of moving up to 220 CFM, making it a reliable choice for forced air heating and cooling systems that require additional static pressure to overcome long duct runs or restrictive geometry. Designed for versatility, this unit features a square to round design, allowing it to integrate seamlessly into rectangular ducts 6x6 inches or larger, as well as round ductwork. With a 3000 RPM motor drawing only 0.6 amps, it provides efficient performance while maintaining a maximum temperature rating of 180°F. For proper HVAC duct integration, contractors typically wire this unit in parallel with the furnace blower or utilize an ABA-1 Air Booster Activator for pressure-sensing automation.

• Improves Airflow Efficiency: Effectively boosts heated or cooled air to distant rooms, reducing the load on the primary blower.
• Flexible Mounting: The AB-2 air booster fits both round and rectangular duct profiles, simplifying inventory for service technicians.
• Heavy-Duty Motor: Features a thermally protected, high-speed motor designed for continuous or intermittent operation.
• Simplified Installation: Designed for branch duct mounting with standard sheet metal screws and a manual or automatic 120V connection.

Can this be used on a vertical duct run? No, this specific model is designed for horizontal or inclined installations to ensure proper motor lubrication and performance. For vertical applications, consult the AB-10 series.

Is an external controller required? While it can be wired to a simple wall switch, we recommend using a pressure-sensitive activator or wiring it in parallel with the furnace blower for automated operation.

What is the maximum duct temperature? The unit is rated for air temperatures up to 180°F. Do not install in systems where temperatures exceed this threshold, such as certain gravity furnaces or near heat exchangers.
