Filters - General Grade Teflon® Cartridges

General Grade Teflon Cartridges are designed for general purpose use wherever a cost effective Teflon membrane filter is required. Typical applications include filtration of aggressive fluids, venting, and air/gas filtration. Teflon membraine is hydrophobic and resists wetting in critical air/vent applications. Priced below special purpose Teflon filter cartridges, General Grade Teflon Cartridges are still manufactured with the same careful attention to quality and performance.

Flow Rate

The following table represents typical water flow at one psi (69 mbar) pressure differential across a single 10 inch cartridge element. The test fluid is water at ambient temperature. Extrapolation for housing with multiple elements and higher pressure drops is acceptable, but as flows increase the pressure drop of the housing becomes more apparent.
