Air fi lters
● Depending on the installation conditions, the fi lter aspect must
be examined to defi ne the cleaning or replacing periodicity.
Spare parts should be planned for.
The pressure drop data are given on the technical catalogue.
Cleaning the fi lters is very important to maintain the required
available pressure of the unit.
On units with a clogged fi lter diff erential pressure switch, an
alarm is triggered on the electronic control when the factory-set
clogging threshold is exceeded depending on the combination
of fi lters selected.
● Gravimetric fi lters (G). Cleaning can be done with a household
vacuum cleaner. Replace them regularly.
● Creased opacimetric fi lters (F). It is necessary to replace them.
Filter removal:
Rotary heat exchanger (optional)
By the right panel (viewed from the front), it is possible to access
inside of the recovery module to carry out the maintenance work.
The removal side panels of the module incorporate stainless
steel quarter-turn latches with 8 mm triangular inserts.
The procedure for extraction and cleaning of fi lters is equal to
that described in the previous section.

● Filters G or G+F: the frames with each type of filters,
gravimetrics and opacimetric (if the unit has includes the
latter), are assembled over sheet steel profi les. By dragging
a tab, they slide along the corresponding rail.
● Filters F+F: the frames with the set of filters F+F are
assembled over a sheet steel profi le. By dragging a tab, they
slide along the rail.

Closing mode:
First rotate 90º (anti-clockwise): closing brings
the latch to the locked position. The door
cannot be opened.
Note: the access panel to the fi lters is fi tted with quarter-
turn latches of stainless steel and 8 mm triangular insert.
