Product description

Features

  • Duct sleeve made of galvanised sheet steel, with flanges and guided vanes on both sides.
  • 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.
  • Flange holes in accordance with DIN 24154, page 2, 7/66.
  • DZL 56/6 B and DZL 56/4 B: Flange holes in accordance with DIN 24145, part 2, 7/90.
  • High degree of protection IP 55.
  • To prevent transfer of vibrations onto the duct system: Use flexible couplings, feet and vibration dampers.
  • Can be fitted in any position.

Motor

  • Asynchronous motor, speed controllable. Exception: Type DZL 40/2 B.
  • Not suitable for ventilating steam-saturated air.
  • EZL / DZL duct fans are non reversible.

AC motor

  • EZL series
  • Rated voltage 230 V, 50 Hz.
  • Thermal overload protection as a standard feature.
  • Potential-free terminal connection, which must be connected to e.g. an MVE 10 full motor protection switch or the control circuit of a contactor.
  • Capacitor motors with operating capacitor ready for use in terminal box.

Electrical connection

  • Terminal box with cable sleeves fitted on the outside.

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 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.
    • 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.
