The fan casing is made of steel with a special polymer coating.
The special casing design protects the motor against direct sprays of water.
The round connecting spigots are rubber sealed. A special sealant applied
on the fan back side ensures a tight contact and adaptation to the wall.
The air is exhausted downwards through a protecting grille against birds
and rodents.
The fan is mounted with fixing lugs.
The fan is equipped with a single-phase external rotor motor and an
impeller with backward curved blades.
The motor has an integrated thermal protection with automatic restart.
The motor is equipped with ball bearings for longer service life and a
dynamically balanced turbine.
Smooth or step fan speed control is performed with a thyristor or
autotransformer speed controller (available upon separate order).
ATTENTION
Make sure the fan has no visible transport damages and check the ordered and the delivered goods for compliance.
