1.8
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 Developments sales documents / Internet).
Operation permitted only for fixed installation within buildings. Maximum permitted
medium and ambient temperature is 40ºC. QuietAir 150 fans conform to enclosure
protection IP45, protection class II and according to VDE0100 part 701 shall be
conformed to install in area 1 of humid areas.
- 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
the fans (cars, aircrafts, ships, etc.). To perform under these conditions is only
possible with release approval by Airflow Developments, in case of standard version
it is not applicable.
- Prohibited use
Misuse of the device is not allowed! 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 the explosive environment is prohibited.
1.9
Performance data
The device type plate is binding for the electrical data; this must be conformed to the
local supply network. On the test stand fan performance was complied with DIN EN
ISO 5801.
1.10
Noise data
The noise data which relate to distances is valid under free field 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.
CHAPTER 2
GENERAL NOTES
2.0
Qualification of staff
Maintenance and installation work must be carried out only by an approved
electrician.
QuietAir 150 fans 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 are not allowed to play with the
device. Cleaning and maintenance must not be carried out by children without
supervision.
2.1
Touch protection
- QuietAir 150 fans are 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.
