Product description
The ECR-A ventilation box is used to extract
air from commercial premises. Thanks to their
design with double-walled and sound-insul-
ated housing, these units are very quiet and
can even be used directly in day rooms.
The unit is installed in ventilation ducts – with
a connection on the inlet and outlet side with
a nominal size of between Ø 125 and Ø 250,
depending on the model.
The motor is designed for continuous opera-
tion. 3 speed levels can be set. These speed
levels are determined when the motor is
connected with the corresponding wiring (for
example, you can choose between 3 out of
4 possible speeds for the ECR supply air
box).
