Product description

Features

  • High temperature centrifugal roof fan for direct or ducted air extraction of commercial and industrial buildings.
  • Horizontal air outlet.
  • High efficiency.
  • Low noise level.
  • Housing made of galvanised sheet steel.
  • Aluminium weather protection hood with openings for engine cooling.
  • Simple installation.
  • The motor is outside the air flow.
  • Suitable for the high temperature range from +65 °C to +150 °C.
  • Centrifugal impellers with backward curved blades made of galvanised sheet steel.
  • Centrifugal impellers are statically and dynamically balanced.

Motor

  • Asynchronous three-phase AC motors.
  • IP 55 degree of protection.
  • IE3 motor.
  • Two-level, three-phase AC, Y/Δ circuit.
  • The temperature in the fan motor is monitored by PTC thermistors. The PTC thermistors must be connected to a release system, that permanently disconnects the fan from the power supply if the temperature is too high.

Electrical connection

  • Connection in the terminal box on the motor.

Safety instructions

  • The fan may only be operated only if the protection against accidental contact with the impeller is guaranteed in accordance with DIN EN ISO 13857.

Special versions
