Food Grade CRT-PES Series PES Membrane Filter Cartridge [Absolute]
The CRT-PES Series Food Grade Filter Cartridges are designed to deliver exceptional filtration performance for the most demanding food and beverage applications, including breweries, wineries, and distilleries.
Engineered with a hydrophilic PES (polyethersulfone) membrane, these filters provide absolute-rated retention and superior bacterial control—ensuring that the final product remains microbiologically stable long after processing. By effectively removing spoilage organisms and particulate contaminants, the CRT-PES series extends the shelf life of filtered solutions while preserving their flavor, aroma, and overall product integrity.
With low extractables, minimal interaction with food components, and broad chemical compatibility (pH 1–14), these cartridges excel in critical filtration stages such as final clarification, microbial stabilization, and sterilizing-grade protection.
Manufactured without animal-derived substances or harmful additives, the CRT-PES Series complies with FDA 21 CFR 177 and EC 1935/2004 food contact regulations, guaranteeing safety, consistency, and reliability in all food-grade environments.

Fit of IFP CRT Cartridges with Filter Housings
The choice of cartridge end cap significantly impacts sealing performance, pressure rating, and fluid distribution. The 226 O-Ring Fin (Code 7) is the most secure and widely used in critical applications, while DOE (Code 0) remains an older technology; its use is limited mainly to non-sterile processes.
End Cap Type | Housing Connection | Details |
226 O-Ring Fin (Code 7) Most Popular - Highest Pressure Rating | Recessed 226 O-ring groove with locking tabs and center receptor for fin | Offers the most secure fit with dual O-ring compression and bayonet locking tabs. The integrated fin aligns the cartridge, enhancing pressure stability and promoting even solution distribution. |
222 O-Ring Flat (Code 2) | Recessed 222 O-ring groove with flat bottom | The housing head features a precision-machined cavity to fit the 222 O-ring, ensuring tight axial compression. Uses a flat receptacle-no locking tabs. |
226 O-Ring Flat (Code 6) | Recessed 226 O-ring groove with flat bottom | Features a wider, deeper groove for 226 O-rings. Provides enhanced sealing over 222 but lacks bayonet lock or fin alignment. |
Flat Gasket (Code 0) Least Popular - Lowest Pressure Rating | Flat knife-edge or gasket seat at both ends | Cartridge is held by compression plates or spring caps. No O-rings or locking tabs-best for low-pressure, general-purpose filtration. |
