The Donaldson FF Series depth filter elements are compatible with the AG, SG, HD, P-EG and PG-EG Donaldson filter housings. Donaldson’s patented UltraPeat technology is used in the FF Series depth filter elements, which are designed for optimal water, oil aerosols and solid particle removal from the compressed air and gas filters, delivering high retention efficiency at low differential pressure. These Donaldson coalescence filter elements have a three-dimensional microfiber fleece coating made of borosilicate glass fibers, which works for oleophobic and hydrophobic applications. The FF Series filter elements are also available in HTNX (high temperature resistant) and HTCR (high temperature and corrosive resistant) versions for use in harsh environments.
