PTFE Membrane
Applications
Solvent Filtration
Process Gas
Tank Vent Filters
Compressed Air Filtration
GTM capsules are made with highly hydrophobic PTFE
membrane. These capsules are designed for use in the filtration
of non-aqueous liquids, aggressive solvents, and as compressed
gas and vent filters.
The capsule media surface area, filter core design, pleat
configuration and pleat packing density have been optimized to
provide increased life resulting in lower filtration operating costs.
Specific applications for GTM capsule filters include filtration
of solvents, alcohols and other non-aqueous liquids. The
hydrophobic membrane makes it ideal for final filtration of
compressed air and process gases, and vent filtration to prevent
contaminants from reaching ingredients in tanks.
Optimized for maximum filter life
Designed for filtration of air and process gases
Vent filtration for the protection of tank contents
Final filtration of solvents, alcohols and other
non-aqueous liquids

Flow Rate / Filtration Area
The following table represents typical air and water flow at a one psi (69 mbar) pressure differential across a single 2 inch capsule with
1.0 ft ² (930 cm²) of media with 1/2” FNPT ports. The liquid test fluid is water at ambient temperature. The gas test fluid is compressed
air at ambient temperature. Higher pressure drops are acceptable, but as flows increase the pressure drop of the housing becomes
more apparent.
