Axial wall fan with square wall plate, DN 450, three-phase AC

Product description

Features

  • Yellow chromated protective grille on the intake side, potection against accidental contact in accordance with DIN EN ISO 13857.
  • 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.
  • Can be fitted in any position.

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.

Motor

  • Asynchronous motor.
  • Speed controllable. Exception: Type EZQ 45/6 B, EZS 45/6 B, DZQ 40/2 B and DZS 40/2 B.
  • Reversible. Exception: Fans with shaded-pole motors (...-E).
  • Not suitable for ventilating steam-saturated air.

Three-phase AC motor

  • DZQ and DZS model series.
  • Rated voltage 400 V, 50 Hz.
  • IP 55 degree of protection. Exception DZQ/DZS... D IP 54.
  • Thermal overload protection as a standard feature. Exception: available on request for DZQ/DZS 25/4 D and pole-changeable axial duct fans.
  • Potential-free terminal connections, which must be connected to e.g. an MV 25 protective motor switch or the control circuit of a contactor.
  • Pole-changeable fans: Ensure overload protection is guaranteed by a motor protection switch provided by the customer.
  • Pole-changeable motors with speed ratios of 8/4 or 4/2 have a Dahlander pole-changing circuit.

Electrical connection

  • To terminal block under the motor cover.

Safety instructions

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

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.
    • Condensation drainage holes.
    • Fans with enhanced anti-corrosion protection.
    • 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.
