With a focus on robust construction, we built a process fan on a combustion blower for an industrial heater application. This installation called for a backward curved blower with a direct-drive motor and an outlet damper with an electric actuator and positioner. We designed it with fewer parts to reduce maintenance in the industrial environment.
Combustion requires fuel, oxygen, and an ignition source. The combustion blower supplies the stable and consistent airflow required to maximize the efficiency and effectiveness of the combustion air system.
At just above 22 inches in diameter, the combustion blower fan is one of our more recent models introduced in 2021 to add higher efficiency options for lower air volume applications. The outlet damper helps control the airflow and reduce the horsepower on the direct-drive motor without reducing speed.
Performance: 80,000 cfm airflow @ 7” wg static pressure @ 0.0737 lb/ft^3 inlet air density
