Motor Features
• Universal mounting all position with IPX4 degree of weather protection
• Patented anti water intrusion system.
• Acoustic dome with super quiet, long vane, backward curved centrifugal fan.
• Airow is dependant on installation and the ducting used.
3
• Using a single 150mm exi duct run you should attain 600m
• The use of a smaller 125 ducting would result in a loss of airow.
• Simple installation: - Mounts onto a 100mm PVC pipe for ultimate strength and allows for easy
Dektite roof sealing.
• Industrial quality motor and fan made in Germany and rated at 40,000 hours.
• Motor is a high eciency PSC type and rated at 62W.

/hr depending on the ducting installation.
General Notes on Installation and Use
This fan unit is designed to be installed using 100mm PVC pipe as the initial connection duct to the fan module,
and is supplied with a 100mm PVC pipe to 150mm exible duct bell-mouth adaptor.
This fan is suitable for connection to multiple duct runs with a minimum inlet area of 11,000 mm². Ducting runs
should be more than 2 metres away from the unit and no more the 4-5 metres (check with supplier if longer
duct length required). Flexible ducting must be extended suciently to present a smooth air passage with
bends of at least the radii of twice the diameter of the duct.
WARNING: The BRB700 must not be ducted into a wall cavity or a ceiling space, where a build up of grease
can occur and become a potential re risk.
NOTE: Fan module and dual foil exi-duct are acoustically matched. The use of semi-rigid or rigid ducting will
result in increased noise levels and void the warranty. See installation instruction notes ‘Why exi-duct’.
Recommended Installation Distance
For the BRB700 motor system, a minimum of 2-3 metres is recommended.
NOTE: Installation closer than these distances will result in higher noise levels. Maximum duct length
4-5 metres. Check with supplier if longer length is required. Do not reduce the duct size at any time
and avoid sharp bends.

3. General
Minimum Mounting Height
This fan unit is intended for mounting at a minimum height of 2.1 metres (measured to the lower part of the
fan impeller) above oor/ground level.
Avoidance of Back Flow
Care should be taken to avoid the back ow of gases into the room.
Safety of Children
This fan is not intended for use by young children or inrm persons without supervision.
Replacement of supply cord
If the supply cord is damaged, it must be replaced by a service agent or suitably qualied person in order
to avoid a hazard.
Why Flexi-duct
Some internet sites strongly recommend the use of rigid ducting over fully exible ducting.
The use of a complete rigid or semi-rigid ducting system will cause an organ piping eect to occur; like a
didgeridoo, where a noise is produced at one end of a hollow rigid pipe and the noise is amplied out the other.
The motor system puts the noise outside the house.
Warning: Installation without the use of at least the minimum recommended length of acoustically matched
exi-ducting will void performance expectations. Any installation problems must be reported to Schweigen.
Call outs relating to incorrect installation will result in a service fee direct to the customer. Schweigen takes
no responsibility for problems caused by faulty installation. Faulty installation may void warranty. A preferred
installer list can be obtained from the Schweigen website www.schweigen.com.au or call 1300 881 693.
