5. FILTERS
Air filters are intended for removing dust, bacteria and other fine particles from the supplied and extracted air. RHP PRO
air handling units are fitted with bag filters, since they have a larger filtering surface than compact filters and will require
less frequent filter replacement. Filters are made of synthetic fabric and can have different filtration classes
1
, i.e. intended for
removing particles of different sizes. In general, supply air ducts are equipped with better filtering class filters than extracted
air ducts, since the cleaned outdoor air is supplied to the premises. Make sure to replace filters on time, as contaminated
filters increase pressure loss of the unit, reduce purification efficiency and increase power consumption.
The unit has an integrated filter contamination monitoring function. It continuously measures pressure difference up-
stream and downstream the filter to evaluate level of contamination. Filter replacement intervals depend on the environ-
ment pollution conditions as well as time of year, for example, during spring and summer filters may be contaminated with
pollen, pubescence or insects, therefore change intervals are shorter. Replace filters if they are visibly dirty even though it is
not time yet and a filter change message is not displayed yet.
Filter type, dimensions, filtering class, number and exact location is specified in the technical data print-out for the spe-
cific unit.

Filter clamping device
To insert/remove filters, pull two handles at the top and bottom of the filter to release a filter clamping device. Filters are
removed/inserted one by one (number of filters depends on the unit size). Once the filters are replaced/inserted, handles are
pushed and the filter clamping device presses the filters to the gaskets.
When inserting filters, make sure that their pockets are upright, filter frames are tightly seated and
gaskets are intact.
