Info & Guides

Description

Long duct runs lose airflow quickly, and the prioAIR is made to make up for that loss. Its aerodynamically optimized impeller and EC motor push air through extended supply or exhaust ductwork in schools, gymnasiums, commercial bathrooms, and manufacturing facilities. Energy input stays low the whole time.

At home, the prioAIR works as a duct booster on extra-long residential runs. It also handles low static pressure jobs in attached garages and crawl spaces. The motor sits right in the airstream, so moving air carries off heat build-up, which helps the fan hold steady over long run times. The sealed, self-lubricated motor bearings never need maintenance.

Key Features and Benefits of the Fantech prioAIR Inline Duct Fan

Variable Speed Control: A built-in 10-volt reference output supports remote manual speed adjustment, so you can match airflow to actual demand instead of running flat out.
Smart HVAC Integration: The prioAIR EC motor can be integrated into smart building HVAC systems, so the fan can take an active part in automated ventilation.
High-Heat Tolerance: The motor runs in air up to 131 degrees F, so you can install it in hot attics and warm ductwork without worry.
Thermal Overload Protection: Built-in thermal overload protection with automatic reset shuts the motor down when it overheats and restarts it once it cools.
cULus Listed: The fan carries a cULus safety certification, which helps you confirm it suits your installation requirements.
Hardwired Power: The fan connects to a 110 to 120-volt hardwired supply, giving you a permanent, cord-free installation inside your duct system.
Sound Rating: The fan is rated at 5.9 sones, where lower numbers mean quieter operation, so plan its location around living areas.

Choose Your Duct Diameter

The prioAIR line comes in 6-inch, 8-inch, and 10-inch duct diameters, and airflow, footprint, and weight all scale with size.

6-Inch (fn12497): This size moves up to 295 cubic feet per minute (CFM) for booster duty on long residential runs, measures 16.1875 x 5.875 x 8.25-Inches (L x W x H), and weighs just 3.3 pounds, so it's easy to hang.
8-Inch (fn12498): This size moves up to 646 CFM for larger residential exhaust or light commercial ventilation, measures 9.6875 x 7.875 x 9-Inches (L x W x H), and weighs 7.5 pounds, so plan for a secure mount.
10-Inch (fn12499): This size moves up to 1,379 CFM for commercial supply and exhaust in spaces like gymnasiums, measures 11.6875 x 9.8125 x 11.9375-Inches (L x W x H), and weighs 13.7 pounds, so plan for solid mounting support.

Sylvane's Expert Take

If you're ventilating a commercial building with extended ductwork, or a residential run that has gone weak at the far end, the prioAIR series covers both jobs. Pick the diameter that matches your existing duct. Then check that the model's CFM covers your load.

The EC motor's speed control matters most here, because running below full output saves energy and cuts noise. That makes any of the 3 sizes a solid long-term choice for duct ventilation.
