Centrifugal fans are one-sided intake fans driven by flange electric motors. They are designed for air exchange in civil construction, industrial premises and agriculture. Centrifugal fans are available in several types, versions and sizes with impeller diameters ranging from 200 mm to 630 mm. Centrifugal fans as a popular HVAC element in constructing and renovating civic amenities and industrial plants are recognised for their quality, simplicity and variability.
RFC fans are low-pressure fans with forward-curved impeller blades, and RFE fans are medium-pressure fans with backward-curved impeller blades. Both of these types are one-sided intake fans directly driven by flange electric motors. RFC-PR fans are low-pressure fans driven by flange motors using belt drives.
