M.4 Filters – always replace filters with new filters with the same characteristics
Filters in supply air and in return air always have the same sizes of frames and the number of filters are always the same. REMEMBER to
order filters for supply air as well as for return air.
To maintain same level of fan power consumption for the air-handling unit, it is very important that filters with the same characteristics
for start pressure as well as lifetime replace factory-mounted filters.
Filter frame for bag filters must be of NON-PVC plastic to ensure safe disposal by incineration.
For each individual air handling unit you will find the data for the factory-mounted filters in Annex 2 that is always provided in a
cover placed inside the air handling unit when the air handling unit is delivered to the final site. Annex 2 is also always available from
Systemair if you can inform us of the production number of the air handling unit. The production number is always printed on the serial
plate that is attached to the unit. You will find an example of this serial plate in section d.2.1 of this manual.
These air handling units are available with filters sizes mentioned below in the table:
