S.3 Filters – always replace filters with new filters with the same characteristics to
maintain SFP value
Filters in supply air and in extract air always have the same sizes of frames and the number of filters for supply air and
extract air are always the same. REMEMBER to order filters for supply air as well as for extract air.
To maintain the factory-calculated SFP values 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.
