Product description

Brief description

  • Axial fan with steel wall ring, in three-phase AC version.
  • For wall installation.
  • Protective grille on the intake side, painted.
  • 8- to 10-blade impellers made of glass fibre reinforced polyamide.
  • Protected against weathering by epoxy coating.
  • Designed for the temperature range -10 °C to +50 °C.
  • 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.
  • Simple mounting by means of square wall plate (accessory).

Air flow direction

  • The air flow direction is marked.
  • For air extraction (clockwise rotation) only.

Three-phase AC motor

  • Asynchronous motor.
  • Not suitable for ventilating steam-saturated air.
  • Rated voltage 400 V, 50 Hz.
  • IP 55 degree of protection.
  • Speed-controllable, exception: DAS 71/8, DAS 80/6 and DAS 112/8. Units controllable via optional frequency converter, e.g. type MF
  • The fan motor must be secured against thermal overload by means of a current-dependent protection device. The protection device is to be provided by the customer.
  • Overload protection with motor protection switch provided by the customer.

Electrical connection

  • In terminal box on motor.

Safety information

  • A star / delta switch, to be supplied by the customer, must be used with fans with power consumption > 4 Kw, in order to limit the starting current.
  • The fan may be operated, with free air intake or discharge, 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.
  • Not controllable with a transformer.
