Are fire-rated cabinet centrifugal fans noisy?

The motors paired with fire-rated cabinet centrifugal fans feature excellent cooling performance, minimizing damage to the fan motor. They can operate continuously for over 30 minutes when the main duct medium temperature reaches 280°C, and sustain prolonged continuous operation at 150°C.

Exceptional high-temperature resistance with broad applicability: Depending on the requirements of high-end civil buildings, variable-speed or multi-speed drive options can be selected to achieve dual functionality (i.e., shared use for ventilation and high-temperature smoke exhaust during fire emergencies).

The superior design of fire cabinet centrifugal fans ensures operational efficiency exceeding 80% for most models, with some sizes reaching over 85%. Their characteristic flat power curve facilitates energy conservation.

Space-efficient design: Footprint is smaller than conventional centrifugal fans. The fundamental fan type is axial flow.

Accommodating architectural layouts, horizontal, vertical, or suspended installations are available. Optional mounting brackets and vibration dampers significantly reduce floor space requirements—occupying two-thirds less area than equivalent-airflow fire-rated cabinet centrifugal fans.
