Product description

Features

  • Housing, base plate, intake nozzle and rain protection cover made of galvanised sheet steel.
  • Galvanized protective grille on the discharge side, protection against accidental contact in accordance with DIN EN ISO 13857.
  • Sturdy eyebolts enable transport by crane.
  • 8-blade impeller 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 switched to ventilation or air extraction (exception EZD ... E).

Air flow direction

  • The following illustration shows the air flow direction:
  1. Standard air flow direction: With air blown across the motor.
  2. Reversing mode: With air drawn across the motor.
  3. Reverse operation (exception EZD ... E): The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.

Motor

  • Asynchronous motor.
  • Reversible. Exception: Fans with shaded-pole motors (".../E").
  • Thermal overload protection as a standard feature.

Three-phase AC motor

  • DZD model series.
  • Rated voltage 400 V, 50 Hz.
  • Degree of protection for DZD... D IP 54.
  • Degree of protection for DZD... B and ... E IP 55.

Electrical connection

  • Connecting cable, approx. 1.7 m long.

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 on request, at an extra cost:
    • Special voltages and frequencies.
    • 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.
