Centrifugal Fan Box/ Cabinet Fan

The centrifugal fan box is a compact ventilation unit that integrates a centrifugal fan with sound attenuation, vibration damping, and filtration functions. Its core operating principle is that the high‑speed rotation of the centrifugal impeller generates centrifugal force, drawing air in axially and discharging it tangentially at high velocity, thereby delivering a relatively high static pressure.

The casing is typically made of galvanized steel, stainless steel, or aluminum alloy, lined internally with sound‑absorbing material, and equipped with access doors and protective screens to effectively reduce operating noise and facilitate maintenance. The impeller is dynamically balanced to ensure smooth and reliable operation. The unit features outstanding advantages such as high pressure, stable airflow, compact design, and flexible installation. Optional accessories include primary/medium‑efficiency filters, variable frequency drives, or explosion‑proof motors to suit various operating conditions.

It is widely used in commercial buildings, industrial plants, underground garages, hospitals, laboratories, cleanrooms, and similar environments for supply air, exhaust, HVAC systems, air purification, and fire smoke extraction. The centrifugal fan box is an ideal choice for medium‑pressure, high‑volume ventilation systems.
