7. FILTERS
Air filters are intended for removing dust, bacteria and other fine particles from the supplied and extracted air. Most VER-
SO STANDARD air handling units are fitted with compact filters or pocket filters in larger units. Filters are made of synthetic
fabric and can have different filtration classes

, i.e., intended for removing particles of different sizes. In general, supply air
flow is equipped with better filtering class filters than extracted air since the cleaned outdoor air is supplied to the premises.
The contamination of the filters is monitored by pressure switches installed inside the unit and set to a certain differential
pressure, based on the type of filter used. If filters of other manufacturer or different filtration class is used, the range of the
pressure switches must be set correctly after their replacement. The pressure switches are set by removing the top cover and
turning the knob to the necessary limit of differential pressure. After the filter becomes dirty and the differential pressure
value is reached, a message will be displayed on the control panel or computer screen.
