Axial roof fan, horizontal air outlet, DN 500, single-phase AC

Product description

Brief description

  • 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 reinforced polyamide.
  • 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 switched to ventilation or air extraction with separate switch (exception EZD ... E).

Air flow direction

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

AC motor

  • EZD type series.
  • Asynchronous motor.
  • Rated voltage 230 V, 50 Hz.
  • Fans “... B” and “... D”: Capacitor motors with operating capacitor in terminal box.
  • Fans “... E”: Shaded-pole motors.
  • Degree of protection for EZD... D and ... E IP 54.
  • Degree of protection for EZD... B IP 55.
  • Speed-controllable. Exception: EZD 35/4 B.
  • Units can be steplessly controlled with optional speed controllers or they can be steplessly switched with an optional 5-step transformer.
  • Reversible. Exception: For fans with shaded-pole motor (“... E”).
  • Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.
  • Thermal overload protection as a standard feature.

Electrical connection

  • Connecting cable, approx. 1.7 m long.

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.
  • A proper fixed installation in a horizontal installation position, a permanent electrical supply cable and correct air supply via shaft or duct is stipulated.

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.
