ROOF FAN TYPE VKR

Fans type ВКР are low-pressure, one-way suction roof fans, installed on the roof of buildings as the main item of an exhaust ventilation structure. Designed for operation without a air duct system, but, provided optimal performance is ensured (when the performance capacity is greater than the minimum), connection with air ducts is also possible. They are used in exhaust ventilation systems of industrial, public and residential buildings.

ROOF FAN TYPE VKR

Fans type ВКР are low-pressure, one-way suction roof fans, installed on the roof of buildings as the main item of an exhaust ventilation structure. Designed for operation without a air duct system, but, provided optimal performance is ensured (when the performance capacity is greater than the minimum), connection with air ducts is also possible. They are used in exhaust ventilation systems of industrial, public and residential buildings.

Roof fans VKR are low-pressure, single-sided inlet radial fans with backward curved blades. The fan casing is made of galvanized steel. A protective cover around the fan housing reliably protects against precipitation from entering the ventilation duct. The impeller is located inside the base and is driven by an electric motor. The motor is attached to the support outside the base and is positioned vertically. The impeller is mounted directly on the motor shaft and rotates clockwise when viewed from the suction side (bottom). The air-gas mixture is sucked in through the inlet and is directed to the outlet due to centrifugal force and the special shape of the blades. The VKR fan can be operated at temperatures of the working environment from -40 ° С to +45 ° С. The environment and air must not contain aggressive gases and vapors that destroy materials, paint coatings and electrical insulation of the product. The fan is manufactured in climatic versions for operation in areas with moderate U and UHL climate and location category 1 according to GOST 15150.
