    Description
    APPLICATION
    • This fan model fits for the following applications:
      • kitchen exhaust ventilation systems;
      • exhaust ventilation systems for removal of post-welding gases;
      • industrial bakery ventilation systems.
    • The fan is designed for ventilation of contaminated, grease-laden, humid and hot air with temperature up to 120 °С in conditions of high air resistance in the system.
    DESIGN DESCRIPTION
    • The fan casing is made of galvanized steel plate and is internally insulated with 50 mm mineral wool layer.
    • The swivel block of the impeller and motor provides easy access to the fan internals for easy and effective cleaning.
    • The intake and exhaust flange diameter match with standard ventilation air ducts.
    • The flanges are equipped with a rubber sealing.
    • The fan is installed in the mounting frames with integrated vibration connectors.
    ELECTRIC MOTOR
    • Equipped with a highly reliable single-phase or threephase motor with squirrel-cage rotor and steel highperformance centrifugal impeller with forward-curved blades (for sizes 150 to 250 mm) or backward-curved blades (for sizes 315 to 450 mm).
    • The impeller is mounted on the motor shaft and is balanced statically and dynamically.
    • The motor has F class motor winding insulation and IP54 ingress protection rating.
    SPEED CONTROL
    • The fan has both step and smooth speed control options with a transformer or frequency speed controller.
    • Several fans may be connected to one controller if the total power and operating current do not exceed the rated controller parameters.
    MOUNTING
    • The fan is designed for connection to round air ducts.
    • The fan is fixed to the wall with the mounting bracket KM-KSK (separate delivery).
    • The fan is connected to power mains on the terminal box on the motor.
    • The cable length must be sufficient with respect to the motor-impeller block movement.
