display (Model No. 3114.200),
temperature-dependent speed control
(Model No. 3120.200, 3235.440, 3235.450)
and/or hygrostat (Model No. 3118.000).
The control unit 3120.200 can

interface (EC fan-and-filter units
and fan-and-filter units with
EMC shielding from an air
throughput of 180 m
Model No. 3240.500/600,

3 1 3 Safety equip e t
The fan is equipped with thermal winding
protection devices for protection against
excess current and, in some cases,
against overtemperature. For rotary current
fans, the winding protection is located in
the star earthing of the motor.
3 1 4 Fi ter
The fan-and-filter unit/outlet filter is sup-
plied with a standard filter mat already in-
stalled. The filter must be checked regular-
ly in accordance with the level of dust
exposure and replaced as necessary.
In order to increase the protection catego-
ry, and in the case of dust with a grain size
of < 10 µm, we recommend the use of fine

filter mats.

The air throughput volume will
be reduced.
Special filter mats are required
for EMC fan-and-filter units
(see accessories).
