3.2 Prohibited uses
Below is a list of specic uses that are prohibited:
• Operaon of the fan with non-gaseous uids or with uids with characteriscs
dierent from those dened to be used with the fan, since structural damage may be
caused to the fan with the possible risk of injury to persons and/or damage to things;
• Operaon of the fan in all types of system with pressures (present or even parally
generated by the fan) greater than 1.2 mes standard atmospheric pressure, since
structural damage may be caused to the fan with the possible risk of injury to persons
and/or damage to things;
• Operaon of the fan in all types of systems classied in accordance with the ATEX
direcve and that move potenally explosive uids, since risks of ignion/explosion
may arise with possible injury to persons and/or damage to things;
• Operaon of the fan in industrial chemical plants where the uid moved is highly
corrosive for the materials used in fan construcon, or in the presence of highly toxic
uids where the construcon methods of casings and the types of seal used are not
suitable for this specic applicaon, since structural damage may be caused to the fan
with the possible risk of injury to persons and/or damage to things;
• Operaon of the fan in mining industry plants and with underground installaons,
since addional risks not considered in the use of the fan above ground may arise,
with possible injury to persons and/or damage to things.
3.3 Life cycle of fan
The reliability of all components is guaranteed if they are properly maintained and if
Nederman original parts and accessories are used.
For safety reasons, guards in electrowelded wire must be replaced every 2 to 3 years.
If the fan is used at constant speed for two work shis every day equivalent to 16 hours,
calculated for 250 days per year, the expected life cycle for the impeller is equivalent to
40,000 hours, ie., 10 years.
In the specic case of operaon at variable speeds, the impeller life cycle must be assessed
on a case-by-case basis, and must also be agreed with Nederman.
Even if it has never been used, an impeller that has been stored for more than ten years
must be checked by Nederman for possible defects before it can be used.
