2.3 Product description

2.3.1 Model series
● EZQ../DZQ.. with square wall plate
● EZS../DZS.. with steel wall ring
2.3.2 Motor versions / models
EZQ../EZS.. single-phase AC models
B and D units: Fans with capacitor motor.
Reversible air flow direction. Reversing mode
with approx. 35 % lower air volume. Capaci-
tor of D units in separate terminal box.
E units: Fans with shaded-pole motor.
One air flow direction, no reversing mode.
12
DZQ../DZS.. three-phase AC models
B and D units: Fans with three-phase AC
motor, reversible air flow direction. Reversing
mode with approx. 35 % lower air volume.
DZQ../DZS.. pole-changing models for
2 speeds
The two speeds are selected with an optional
pole changing switch, e.g. Maico P1.
Product features
● Wall fans in nominal sizes DN 200 to
DN 600.
● Units for air extraction or ventilation,
depending on installation position.
Reversible air flow direction. Exception:
E units with shaded-pole motor with one
air flow direction.
● Air flow and rotational direction are
marked by arrows on the fan housing
( Figs. B and C).
● The units are switched on or off with an
optional switch.
● The units feature a speed-controllable
asynchronous motor. Exception:
DZQ 40/2 B and DZS 40/2 B are not
speed-controllable.
● The units are not approved for operation
on a frequency converter (special versions
available on request).
● EZQ/EZS.. B single-phase AC models
with connection-ready capacitor [3].
● EZQ/EZS.. D single-phase AC models
with ready-wired capacitor [3].
● Protective grille [1] for protection against
accidental contact according to EN
ISO 13857.
