Constructed with gradient density thermally-bonded polypropylene microfiber media, absolute-rated Flotrex AP (FAP) filters (Figure 1) combine exceptional solids-holding capacities with precise micron retention ratings. The FAP filters are constructed of FDA acceptable high-purity polypropylene.

FAP filters are absolute-rated for air, gas and liquid filtration with low pressure drop across the wide range of 0.65 to 40 microns. Sheets of melt-blown media are layered to provide absolute particle retention, high solids loading and long service life.
