HTFC Fireproof Cabinet-Type Centrifugal Fan
A centrifugal fan is a machine that, by means of mechanical energy input, increases gas pressure and conveys gas; it is a type of driven fluid‑handling machinery. Centrifugal fans are widely used for ventilation, dust removal, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; for ventilation and draft in boilers and industrial furnaces; for cooling and ventilation in air‑conditioning equipment and household appliances; for drying and conveying grains; and for providing wind‑tunnel airflow as well as inflating and propelling hovercrafts.
