Field Controls AB-8 Duct Air Booster Fan

The Field Controls AB-8 Duct Air Booster is a high-efficiency duct booster fan designed to improve airflow in heating and central air conditioning systems. With a compact 8 inch round duct footprint and 120 Volt AC operation at 60 Hz, this unit delivers reliable performance where airflow is needed most.

Engineered for steady, near-silent operation, it pairs rugged construction with energy-conscious performance. Boasting a 0.8 Amp draw, 45 Watt power rating, and a powerful 425 CFM airflow, the AB-8 helps balance temperatures and boost supply to zones that underperform.
