GENERAL
The exhaust centrifugal fan Extero is designed for exhaust ventilation of
various premises.
The fan is designed for vertical installation at exhaust vents of Ø 100 up
to 200 mm air ducts.
The fan must be grounded.
The fans are allowed for operation only after nal mounting, that includes
installation of protecting devices in compliance with DIN EN ISO 13875 (DIN
EN ISO 12100) as well as other construction safety equipment.
The fan design is regularly improved, so some models can slightly dier
from those ones described in this operation manual.

Capacitor
Centrifugal impeller
Terminal block
Fan cover
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 xing 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).
