Operational area
- Appropriate use:
QuietAir 150 fans are used to convey normal or slightly dusty (particles size < 10
µm), little aggressive and humid air, into moderate climate and suitable area of its
performance curve (see Airflow sales documentation / Internet). Operation permitted
only for fixed installation within buildings. Maximum permitted medium and ambient
temperature is 40ºC. QuietAir 150 fans conform to protection rating IP45, protection
class II and according to VDE0100 part 701 can be installed in zone 1 of your wet
room.
- Rationally foreseeable misuse
The fans are not suitable for use under difficult conditions such as high humidity,
aggressive media, longer downtimes, strong pollution, and excessive workload due
to climatic, technical or electronic influences. The same applies for the mobile use of
this fan (cars, aircrafts, ships, etc.). To perform under these conditions please check
with Airflow Developments Limited before installing.
- Prohibited use
Anything other than the intended use is not permitted. Solids or solid impurities > 10
µm in transporting medium as well as liquids are not allowed. Transporting medium
which are aggressive against the fan material as well as abrasive media is not
allowed. Usage of the fan in an explosive environment is prohibited.
1.9
Performance data
The device type plate is binding for the electrical data; this should conform to the
local supply network. On the test stand fan, performance complied with DIN EN ISO
5801.
1.10
Noise data
The noise data which relate to distances is valid under free flow conditions.
After installation the sound pressure level can vary significantly from the catalog
values since it strongly depends on the installation conditions, for instance the
absorption capacity of the room, the room size etc.

GENERAL NOTES
2.0
Qualification of staff
Maintenance and installation work must be carried out only by an approved
electrician.
The QT150 HT should not to be used by children and persons with reduced physical,
mental or sensory capacities, without proper practical experience or expertise,
unless they are controlled or instructed on the product operation by the person(s)
responsible for their safety. Children should not play with the device. Cleaning and
maintenance must not be carried out by children without supervision.
2.1
Touch protection
The QT150 HT is supplied with a standard suction side protective grid. Depending on
the installation conditions protection against accidental contact on the discharge side
may also be required. Appropriate protective grids are available as an accessory.
- According to the installation method (for instance installation in ventilation canals or
covered aggregates) fans are already protected and in such cases they do not need
a protective grid. It should be noted that the operator is responsible for compliance
with the current requirements and is liable for accidents.
