Ultipor® GF Plus filters have a pleated high area construction for long service life. The medium uses a binder resin which coats the glass fibers, imparting a positive zeta potential in aqueous service. The resin also bonds the glass fibers to a polyester substrate, producing a rugged composite medium. Applications for such turbine lube filter cartridges are numerous as most suspensions are negatively charged in aqueous solution, including not only particles but bacteria and viruses. Some Ultipor GF Plus filter grades efficiently remove sub-microscopic haze from a wide variety of pharmaceuticals and cosmetics, including colognes.

Ultipor GF Plus turbine lube filter cartridges have a fixed pore construction which precludes unloading or media migration.

Ultipor GF Plus elements with polypropylene hardware in a double open-ended UNI CAP configuration are rated to withstand differential pressures of 5.2 bard (75 psid) @ 38°C (100°F) and 3.1 bard (45 psid) @ 82°C (180°F).

When constructed in a single open-ended AB configuration, the element can withstand differential pressures of 5.2 bard (75 psid) @ 27°C (80°F) and 3.8 bard (55 psid) up to 82°C (180°F).
