EZR 30/6 B

short description

Axial duct fan, DN 300, alternating current

Product description

AC model

  • Axial duct fan, in single-phase AC version.

Brief description

  • Duct sleeve made of galvanised sheet steel, with flanges on both sides.
  • 8-blade impellers made of glass fibre reinforced polyamide
  • Flange holes in accordance with DIN EN 12220:1998.
  • DZR 56/6 B and DZR 56/4 B: Flange holes in accordance with DIN EN 12220: 1998.
  • To avoid transmission of vibrations to the duct system: Use flexible couplings, feet and vibration dampers.
  • Thermal overload protection as a standard feature.
  • Fans meet the requirements of the European Ecodesign Directive (EC) No.327/2011 Directive 2009/125/EC.
  • 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.
  • Can be fitted in any position.

Air flow direction

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

AC motor

  • EZR type series.
  • Asynchronous motor.
  • Not suitable for ventilating steam-saturated air.
  • Rated voltage 230 V, 50 Hz.
  • High degree of protection IP 55. Exception EZR... D IP 54.
  • Speed-controllable.
  • Units can be steplessly controlled with optional speed controllers or they can be steplessly switched with an optional 5-step transformer.
  • Reversible.
  • Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.
  • Capacitor motors with operating capacitor ready for use in terminal box.
  • Thermal overload protection as a standard feature.
  • Potential-free terminal connections, which must be connected to, e.g., an MVE 10-1 full motor protection switch (not suitable for EZR 25/4 D, EZR 30/6 B and EZR 35/6 B) or the control circuit of a contactor.

Electrical connection

  • Terminal box with cable sleeves fitted on the outside.

Safety information

  • 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, e.g., with Maico SG protective grille.

Special versions

  • The following special versions are available on request, at an extra cost:
    • Special voltages and frequencies.
    • PTC thermistor, potential-free terminal connection.
    • 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.
