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
  • The fan is fitted with a reliable maintenance-free single-phase motor with short circuit rotor and a high-efficient steel centrifugal impeller.
  • The motor is equipped with integrated thermal contacts with leaded outside terminals for connection to an external protection device.
  • 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.
