EVO-S COMPACT
COMPACT AIR HANDLING UNIT
OPERATION AND MAINTENANCE MANUAL
4. FUNCTIONAL UNITS
Depending on the functional requirements resulting from
the air handling process, the units are equipped with the
following batch units:
4.1 MX Mixing and recirculation
All rectangular inlets and outlets in the units are equipped with
flexible connection. They are screwed to the damper or the air
handling unit cover. Size of flexible connection and rectangu-
lar dampers for individual units according to section 2.2.4
Connections are secured for transport by means of metal
strips. The flexible connection is equipped with a yellow-green
grounding wire, which should not be removed, but connected
to the duct system.
4.2 Air filters P, B, MP
Air filters can be supplied in accordance with PN-EN 779 or
PN-EN-ISO 16890. Filter classification is given in the Table 9.

In the pre-filtration section PF, cassette filters class G4÷M5,
bag filters class G4 and M5 or minipleat class M5 are instal-
led.
In the secondary filtering section SF, bag filters class F7 and
F9, minipleat class F7 and F9 filters
The dimensions of the filters used are specified in the KT
certificate.
The filters must be replaced when the permitted pressure
drop at the filter is exceeded (Table 10) or according to a vi-
sual decision in the automation system.
The unit must be switched off during filter renewal.
The class of new filters has to correspond to the class of the
used filters.
During filter renewal also the filtration section has to be cle-
aned.

4.2.1 Cassete Filter G4 and M5
G4/M5 cassette filters (panel filters) are fabric filters in metal
casing; they are designed for preliminary air treatment.
Cassete filters are 50mm deep. They are mounted in straight
SR type guides.
Self-adhesive seals for sealing are mounted on the walls of
the air handling unit housing at the point of filter adhesion
and between cassettes, if there are more filters.

4.2.2 Minipleat filters
M5 minipleat filters
M5 class minipleat filters are filters made of non-woven fa-
bric formed into filter packets in galvanized sheet casing;
they are designed for preliminary air treatment.
M5 minipleat filters are 48mm deep. They are mounted in
straight SR type guides.
Self-adhesive seals for sealing are mounted on the walls of
the air handling unit housing at the point of filter adhesion
and between cassettes, if there are more filters.
M5 minipleat filters are not to be regenerated and must be
replaced with new ones.
The dimensions of the filters used are specified in the KT
certificate.
