short description

Axial wall fan for recessed-mounted installation, DN 400, three-phase AC

Product description


  • For recess mounting.
  • Can be fitted in any position.
  • Wall sleeve made of galvanised sheet steel.
  • 8-blade impellers made of glass-fibre filled polyamide. Dynamically balanced at two levels, in accordance with performance level 6.3, DIN ISO 1940, Part 1.
  • Protective grille made of plastic on the intake side, pearl white, protection against accidental contact in accordance with DIN EN 13857.

Air flow direction

  • The following illustration shows the air flow direction.
  1. Air flow direction A: With air drawn across the motor, standard
  2. Air flow direction B: With air blown across the motor, available on request
  3. Rotational direction
  4. Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.


  • Asynchronous motor.
  • Reversible. Exception: Fans with shaded-pole motors (...-E).
  • Not suitable for ventilating steam-saturated air.

Three-phase AC motor

  • DZF model series.
  • Rated voltage 400 V, 50 Hz.
  • IP 55 degree of protection. Exception DZF... D IP 54.
  • Thermal overload protection as a standard feature. Exception: DZF .../D.

Electrical connection

  • To terminal block under the motor cover.

Safety instructions

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

Special versions

  • The following special versions are available at extra cost on request:
    • Special voltages and frequencies.
    • Single-phase motors with thermal contacts or PTC thermistor, with potential-free terminal connections.
    • 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.
