BLAUBERG Ventilatoren GmbH is happy to oer your attention the
exhaust centrifugal fan Extero.
INTRODUCTION
The present operation contains technical description, technical data
sheets, operation and mounting guidelines, safety precautions and warnings
for safe and correct operation of the fan.
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 dier
from those ones described in this operation manual.
SAFETY RULES
The fan complies with the requirements according to the EU norms
and directives, to the relevant EU-Low Voltage Equipment Directives, EU-
Directives on Electromagnetic Compatibility.
All operations related to the electrical connection of the fan, like servicing
and repair works are allowed only after the disconnection from power mains.
All mounting and servicing operations are allowed for duly qualied
electricians with valid electrical work permit for electric operations at the
units up to 1000 V after careful study of the present operation manual.
Please follow the safety regulations and working instructions (DIN EN 50
110, IEC 364).
Make sure the impeller and the casing are not damaged before
connecting the fan to power mains. The casing internals must be free of any
foreign objects which can damage the impeller blades.
Disconnect the fan from power mains prior to any operations related to
the servicing and repair works. Make sure the rotating parts have come to a
full stop.
Take measures to prevent contact with the fan to avoid physical damages
during the fan test and start-up.
Misuse of the product or any unauthorized modication are not allowed.
The fan is designed for connection to ac single-phase or ac three-phase
power mains, see "Technical Data". The fan is rated for permanent operation
during non-stop power supply.
Take steps to prevent ingress of smoke, carbon monoxide and other
combustion products into the room through open chimney ues or other
re-protection devices. Sucient air supply must be provided for proper
combustion and exhaust of gases through the chimney of fuel burning
equipment to prevent back drafting. The maximum permitted pressure
dierence per living units is 4 Pa.
The transported air must not contain any dust or other solid impurities,
sticky substances or brous materials.
The fan is not designed for use in an inammable and explosive medium.
The transported air must not contain any dust or other solid impurities,
sticky substances or brous materials.
The fan is not designed for use in an inammable and explosive medium.
The transported medium must not have an aggressive eect on steel at
the temperature stated in the table 1 of the section “Technical data”.
Do not close or block intake or exhaust vent not to disturb the normal
air passage.
Do not sit on the fan and do not put objects on it.
In case of unusual sounds, smoke disconnect the fan from power supply
and contact the service centre.
Follow the manual guidelines to ensure trouble-free operation and long
service life of the product.
Hazardous parts access and water ingress protection standard IPX4.
STORAGE AND TRANSPORTATION RULES
Store the delivered fan in the manufacturer's original packing box in a dry
ventilated premise with the ambient temperature from +5 °C up to + 40°C.
Store the fan in an environment with minimized risk of mechanical
damages, temperature and humidity uctuations. Store the fan inside a room
or under a shelter.
Transportation of the fan is allowed by any vehicle provided the fan is
transported in the original package and is protected against weather and
mechanical damages.
Use hoist machinery for handling and transportation to prevent possible
mechanical damages. Full the requirements for transportation of the
specied cargo type during cargo-handling operations.
Do not expose the fan to extremely low or high temperatures.
MANUFACTURER'S WARRANTY
The fan complies with the requirements according to the EU norms
and directives, to the relevant EU-Low Voltage Equipment Directives, EU-
Directives on Electromagnetic Compatibility.
The manufacturer hereby warrants normal operation of the fan over the
period of two years from the retail sale date provided observance of the
installation and operation regulations.
In case of failure due to faulty equipment during the warranty period the
consumer has the right to exchange it.
If case of no conrmation of the sale date, the warranty term shall be
calculated from the manufacturing date.
The replacement is oered by the Seller.
The MANUFACTURER shall not be liable for any damage resulting from
any misuse of or gross mechanic interference with the fan.
Full the operation manual requirements to ensure a trouble-free and
long service life of the fan.
WARNING

Terminal block
Capacitor
Casing
Fixing lug
Centrifugal impeller
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).
ATTENTION
Make sure the fan has no visible transport damages and check the ordered and the delivered goods for compliance.
