GPM Capsule Filters
Polypropylene Membrane
Applications
Solvents
Process Gases
Tank Vent
Compressed Air
GPM capsules are manufactured with inherently hydrophobic
polypropylene membrane. They are designed for use in the
filtration of non-aqueous liquids, for filtration of gases and as
vent filters. Each GPM filter lot is tested using the water intrusion
method to assure quality before it is released from manufacture.
The capsule membrane surface area, filter core design, pleat
configuration and pleat packing density have been optimized to
provide increased life.
Optimized for maximum filter life
Vent filtration for the protection of tank contents

inal filtration of solvents, alcohols and other nonaqueous liquids
Applications for GPM capsule filters include final filtration of
solvents and alcohols, final filtration of compressed air and
process gases, and tank vent filtration to prevent contaminants
from reaching critical ingredients while in storage.

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.
