Resin Bonded Filters
resin bonded filters Sentry resin bonded filter cartridges use a unique two-stage filtration design that maximizes particle removal and prolongs service life in viscous fluid filtration applications. An outer prefilter wrap increases cartridge strength and eliminates residual debris associated with conventional, machined, resin bonded cartridges.

Polypropylene pleated filters
Polypropylene pleated filters incorporate a combination of melt blown polypropylene and thermally bonded media to provide high surface area, surfactant-free, and non-fiber releasing filtration. All-polypropylene construction offers chemical resistance to acids, bases, salts, and most organic solvents.

Polyolefin Filters
Sentry’s Polyolefin Filter Cartridges Sentry’s polyolefin filter cartridges are the most economical high strength filter cartridges available. Featuring an integral rigid thermally bonded construction, Polyolefin filters provide consistent filtration for a wide variety of fluids. The fixed pore structure acts as a sieve-like particle “classification” filter for high solids coatings and slurries, allowing product to pass while stopping large agglomerates and contaminants.

PTFE membrane filters
Sentry all-Teflon PTFE membrane filters offer exceptional flow capability and particle retention performance. Sentry all-Teflon filters offer the broadest fluid compatibility available and are recommended for aggressive chemical and high temperature applications. All PTFE/PFA filter cartridges are processed to meet the filtration requirements of ultra-high purity liquids used in advanced electronics manufacturing.Sentry all-Teflon PTFE Membrane Filters

PTFE/Polypropylene Membrane Filters
Sentry PTFE membrane filters offer exceptional flow capability and particle retention performance. The PTFE membrane with polypropylene support construction provides broad chemical compatibility with low extractable levels. As a lower cost alternative to all-Teflon, the Sentry PTFE/Polypropylene filters are suitable for less aggressive chemical applications and most venting and gas applications.
