Centrifugal fire fan cases are very popular in buildings, mainly using double suction forward multi wing or rear curved centrifugal fans, soundproof cabinet type boxes. Centrifugal fire fan cases have the advantages of smooth operation, low noise, small size, beautiful appearance, and simple installation, and are widely used for pipeline air supply and exhaust in factory workshops, commercial entertainment and other occasions.

The centrifugal fire fan box can be equipped with an air filter that can filter dust at the air inlet according to user requirements, or a medium to low efficiency filter section can be added as a purification fan box (the length and size of the box will be determined separately). The fan case can also adjust the air volume and pressure through power voltage regulation or power frequency conversion according to requirements. After configuring the electric control box, it can be remotely controlled.
