short description

Axial wall fan with steel wall ring, DN 350, single-phase AC

Product description

Features

  • Yellow chromated protective grille on the intake side, potection against accidental contact in accordance with DIN EN ISO 13857.
  • 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.
  • Can be fitted in any position.

Air flow direction

  • The following illustration shows the air flow direction:
  1. Air flow direction A: With air drawn across the motor, standard
  2. Air flow direction B: With air blown across the motor, available on request
  3. Rotational direction
  4. Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.

Motor

  • Asynchronous motor.
  • Speed controllable. Exception: Type EZQ 45/6 B, EZS 45/6 B, DZQ 40/2 B and DZS 40/2 B.
  • Reversible. Exception: Fans with shaded-pole motors (...-E).
  • Not suitable for ventilating steam-saturated air.
