Centrifugal fans are fluid machines that rely on the centrifugal force generated by the rotation of an impeller to draw gas in axially and discharge it radially.
Core Working Principle
A motor drives the impeller to rotate at high speed, and the blades cause the gas to move in a circular motion.
Under the action of centrifugal force, the gas is thrown towards the edge of the impeller and enters the volute casing.
The gas velocity decreases and the pressure increases inside the casing, eventually being discharged from the outlet.
Main Features
High air pressure, able to overcome the resistance of long pipelines or complex operating conditions.
Stable flow rate, wide applicability, covering everything from low-pressure, high-volume to high-pressure, low-volume.
Compact structure, reliable operation, and relatively low maintenance costs.
Common Application Scenarios
Industrial ventilation: factory air exchange, workshop cooling, dust removal.
Air conditioning systems: central air conditioning supply air, return air, and fresh air treatment.
Environmental protection: waste gas treatment, sewage treatment aeration, flue gas emission.
Others: boiler induced draft, mine ventilation, grain drying, etc.
