Electronics PTFE Membrane Capsules - 1

ETM Capsule Filters PTFE Membrane Applications Solvent Filtration Non-Aqueous Solutions Tank Vents Process Gas ETM capsules are made with highly hydrophobic PTFE membrane. These capsules are designed for use in the filtration of non-aqueous liquids and aggressive solvents. ETM filters are also used as compressed gas filters and vent filters. Each capsule module is individually integrity tested before it is released from manufacture. The capsule media surface area, filter core design, pleat configuration and pleat packing density are optimized to increase life and lower filtration operating costs. Optimized for maximum filter life D esigned for filtration of air and process gases ETM capsule filters are most often used as final filters for gases and non-aqueous liquids at the point-of-use, such as at tools. They are also ideal for vent filtration to prevent contaminants from reaching solutions in tanks. V ent filtration for the protection of tank contents ETM Capsule Filters - Filtration Area Capsule Length PTFE Membrane 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.
