Donaldson FF UltraPleat™/ FFP / P-FF depth filters are designed for the removal of water and oil aerosols as well as solid particles from compressed air and gases with high retention efficiency at a low differential pressure.
The coalescence filter elements are based on three-dimensional microfiber fleece made of coated borosilicate glass fibers, which works for oleophobic and hydrophobic applications. The FF UltraPleat filter elements, as well as the FFP filter elements, are suitable for AG, SG, and HD filter housings. The P-FF filter elements are used in our P-EG and PG-EG housings.
The elements are also available in HTNX (high temperature resistant) and HTCR (high temperature and corrosive resistant) versions for use in harsh environments.
