GPVWB Capsule Filters
High Capacity Hydrophobic PVDF Membrane
Applications
Compressed Air
Tank Ventilation
Fermentation Air
Non-Aqueous Solutions
Solvents
GPVWB capsules are made with high capacity hydrophobic
PVDF membrane. The high capacity membrane provides high
dirt holding capacity, excellent throughput and high efficiency
particle retention. These capsules are designed for use in the
filtration of non- aqueous liquids, 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.
Optimized high capacity membrane for maximum life
Specific applications for GPVFB 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 for vent filtration to
prevent contaminants from reaching ingredients in tanks.
Designed for filtration of air and process gases
Vent filtration for protection of tank contents
Final filtration of solvents, alcohols and other
non-aqueous liquids

Flow Rate / Filtration Area
The following table represents typical water or air/gas flow at a one psi (69 mbar) pressure differential across a single 2 inch capsule
with 1.0 ft² (930 cm²) of media with 1/2” FNPT ports. The test fluids are water or compressed air at ambient temperature. Higher
pressure drops are acceptable, but as flows increase the pressure drop of the housing becomes more apparent.
