  • 8-blade impellers made of glass-fibre reinforced polyamide
  • Protective grille made of plastic on the intake side, pearl white, protection against accidental contact in accordance with DIN EN 13857.
  • Thermal overload protection as a standard feature.
  • Vibration-free running due to dynamically balanced impeller and motor (shaft-rotor), according to quality class 6.3, DIN ISO 1940, part 1.
  • High efficiency on the ventilation side, low operating noise.
  • Increased durability due to high-quality materials such as quiet ball bearings.
  • Fans are maintenance-free.
  • Reversible operation of the fans possible.
  • Customer-specific special voltages available, as special designs, on request and at extra cost.

Air flow direction

  • The air flow direction is marked.
  • Standard exhaust air mode, air flow direction with air drawn across motor.

Single-phase AC motor

  • Asynchronous motor.
  • Rated voltage 230 V, 50 Hz.
  • IP 54 degree of protection. Exception EZF... D, EZF ... E IP 54.
  • Fans “... B”: Capacitor motors with operating capacitor on the protective grille or on the wall sleeve. IP 55 degree of protection.
  • Fans “... D”: Capacitor motors with operating capacitor in terminal box. IP 54 degree of protection.
  • Fans “... E”: Shaded-pole motors, non-reversible.
  • Thermal overload protection as a standard feature.
  • Speed controllable. Units can be steplessly controlled with optional speed controllers or they can be steplessly switched with an optional 5-step transformer.
  • Reversible. Exception: For fans with shaded-pole motor (“... E”).
  • Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.
  • Not suitable for ventilating steam-saturated air.

Electrical connection

  • On terminal block in end cover of the motor.

Safety information

  • The fan can be operated only if the protection against accidental contact with the impeller is guaranteed to be in accordance with DIN EN 13857 for fans with a free inlet.

Special versions

  • The following special versions are available on request, at an extra cost:
    • Special voltages and frequencies.
    • Single-phase motors with thermal contacts or PTC thermistor, potential-free terminal connection.
    • Impellers made of aluminium.
  • Information on operation at temperatures occasionally below -20°C available upon request.
  • If operating with frequency converters, the factory must be consulted.
  • Feasibility must be checked in each case.
