10 - FILter
The 4GM has, as standard, a high-efficiency F6 filter in
accordance with standard EN 779 or EU 6 in accordance
with Eurovent 4/5. Fire rating medium M1.
The filter can be removed through a door in the underside
of the unit. The ease with which the filter can be removed
and replaced is an important benefit for service technicians.
Air filters should be changed regularly (F). How often this is
needed depends on the cleanliness of the working environ-
ment and the rate at which the filter becomes clogged.
If clogged filters are not changed they can increase the
pressure drop, trapped dust particles may be given off and
entrained in the air supply, and the general performance of
the 4GM may be degraded as the air flow reduces.
