Special centrifugal end-suction fans of the VVN and VVR series are large-capacity units equipped with a guide mechanism and an impeller with ten backward-curved blades.
Special fans VVN and VVR feature high performance and require the use of powerful motors. They are widely used in various gas purification systems for metallurgical and mining industries, as well as in air treatment systems for stationary steam boilers of various capacities. These fans can operate both indoors and outdoors at air temperatures ranging from -30°C to +200°C. Please note their substantial weight — each unit weighs around five tons, not including the motor.
