PPD capsules are made with polypropylene microfiber media.
Designed with the optimal filtration area, the filters remove large
amounts of particulate and other contaminants. PPD capsules
protect critical membrane filters downstream by removing
99.9% of contaminants at the rated pore size.
Specific applications for PPD capsule filters include pre-filtration
of bulk pharmaceutical chemicals, water, buffers, solvents,
alcohols and other liquids. PPD capsules also protect membrane
filters in filling applications for SVPs, LVPs, diagnostics,
ophthalmics, biologicals and other products.

igh capacity for long life
Polypropylene exhibits broad chemical compatibility, so it is
particularly suited for the filtration of chemicals and solvents
used in drug making processes. PPD capsule elements are
integrity tested during manufacture and are flushed to assure
cleanliness in critical process applications.

Flow Rate / Filtration Area
The following table represents typical water 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 fluid is water at ambient temperature. Higher pressure drops are acceptable, but as
flows increase the pressure drop of the housing becomes more apparent.
