9.5.1 Routine maintenance for all filters
As a general requirement and depending on the operating conditions, all filters must
be checked at regular intervals and replaced if necessary. Carry out the following main-
tenance steps:
•
Check filters for debris, damage and odour.
•
Clean filter chamber.
•
Check if the maximum allowed pressure difference (refer to RLT 01 guideline -
German Association of HVAC Manufacturers) or pressure difference specified by
the manufacturer is exceeded - if so - replace the filter.
Hygiene inspection
Observe current legal regula-
tions and standards! Fläkt-
Group recommends
maintenance steps and inter-
vals specified in VDI 6022
Even if the filter shows no visible signs of dirt, microbial growth and mould may propa-
gate through the filter as a result of its long-term use (in air with low dust content).
•
The filters must be replaced regularly (at least every 6-9 months), even if dirt is
barely visible.
9.5.2 Bag filters/panel filters/fine-particle filters
Carry out the following maintenance steps:
•
Check filter and filter frame for dirt, corrosion and damage, replace if necessary.
The end pressure difference of bag filters varies, refer to the relevant technical data for
details (see filter identification plate).
•
Replace the filter if the maximum pressure difference is reached.
HAZARDOUS VOLTAGE AND RISK OF ROTATING COMPONENTS! OB-
SERVE PERSONAL PROTECTION MEASURES
Please consider the safety instructions on page 58.
DANGER OF INFLAMMABLE MATERIALS!
There is a risk of inflammable filter material that could cause fire. Depending on the
filtered substances, used filters pose a significantly higher fire hazard. Keep filters
away from open fire!
NOTICE!
We recommend never to operate the system without a filter and always to keep a
set of spare filters on stock. Ensure that the filter surface is not damaged as this
can destroy the filter during service. In this case FläktGroup can not assume any
warranty for the filter grade.
Environmental damage!
Heavily contaminated filters pose a health risk and may adversely affect produc-
tion processes. Depending on the filtered substances, dirty filters should be
treated as special waste and must be disposed of in an environmentally-friendly
manner and in accordance with current codes and regulations.
