DriPak® 25 is a unique synthetic pocket filter which can be used as a
prefilter or as a final filter. Due to its high dust holding capacity and
robust pocket design it is particularly suited for difficult operating
conditions, including variable air volume, turbulent airflow and
repeated fan shutdown.
When used as a prefilter, it protects higher efficiency filters from
unnecessary dust loading, prolonging their service life. As a result,
the frequency with which final filters need to be changed is reduced-
increasing the cost effectiveness of the air handling system. The filter
displays a low resistance to airflow and is classified G4 in
accordance with EN779.
