Certified Bio-Burden Reduction Without Flavor Strip

Fibers and coarse depth media are designed to trap bulk particulates, but they cannot provide a verified barrier against microscopic bacteria. The Hy-PureFB™ Pleated Membrane Filter series shifts the mechanism to absolute surface filtration via a highly controlled polymer pore matrix.

Our polyethersulfone membrane is inherently hydrophilic, meaning it wets completely and uniformly with water. This property allows for high fluid transmission rates at exceptionally low differential pressures. More importantly, the polymer structure is naturally low-binding. It will not adsorb or strip out essential color pigments, delicate proteins, or specific flavor compounds that define the identity of your wine, beer, or juice.

The results are predictable and repeatable:

• Validated Retention: The 0.2-micron membrane option is fully validated to retain Brevundimonas diminuta, providing a secure biological barrier directly upstream of your filling nozzles.
• Optimized Flow Kinetics: The high pore density of the pleated PES sheet keeps fluid moving efficiently, preventing production bottlenecks during long bottling runs.

Thermal Integrity During CIP and Steam Stabilization

Sanitary operations rely on aggressive thermal and chemical sanitation to eliminate biofilm accumulation in process lines. A standard commercial filter cartridge often suffers from pleat deformation, longitudinal splitting, or endcap separation under the stress of rapid temperature fluctuations.

Hy-PureFB™ Pleated Membrane Filter cartridges are built to handle these rigorous Clean-In-Place cycles. The internal polyolefin core and protective outer cage are engineered with heavy-duty structural ribs. Every component is thermally welded to the next without the use of toxic glues, epoxies, or secondary adhesives.

This robust mechanical construction ensures the cartridge maintains its physical form and micron efficiency throughout repeated hot water sanitization routines and in-line steam sterilization cycles up to 135°C (275°F).

The Adapter Code (The Fit)

If your replacement filter doesn’t lock into the housing seat properly, fluid will bypass it entirely. The two most common industrial configurations are:

Code 3: Uses double 222 O-rings with a flat closed top
Code 7: Uses double 226 O-rings featuring a twist-lock bayonet mechanism and a pointed fin at the top

Strict Regulatory Compliance for Consumer Safety

Every material used to construct the Hy-PureFB™ Pleated Membrane Filter element undergoes strict quality assessment. All polymers, support netting, and internal cores are manufactured from 100% FDA-listed materials for food contact compliance.

Standard Formats and Operational Parameters

To fit seamlessly into your existing filtration train, Hy-PureFB™ Pleated Membrane Filter cartridges are available in industry-standard lengths from 10 to 40 inches. They can be configured with multiple industrial endcap styles, including the standard Code 7 locking bayonet with dual 226 O- rings, Code 3 with dual 222 O-rings, and traditional double-open-end flat gaskets.

FAQ Most common questions process engineers

What makes polyethersulfone (PES) the preferred membrane material for final beverage filtration?

Polyethersulfone is ideal for food and beverage applications because it is inherently hydrophilic (wets easily with water) and features a highly uniform, asymmetrical pore structure. This layout provides exceptional flow rates and a low initial clean pressure drop. Additionally, PES is completely non-hazardous and features exceptionally low protein- binding properties. It will not strip out the delicate flavor profiles, aromatic compounds, or color pigments that give your wine, beer, or juice its distinct identity.

How is the 0.2 micron Hy-PureFB™ Pleated Membrane Filter validated for sterile performance?

Our Hy-PureFB™ Pleated Membrane Filter 0.2 micron absolute-rated membrane elements undergo rigorous liquid challenge testing during development. They are validated to retain a minimum challenge concentration of 10 7 colony-forming units (CFU) per square centimetre of Brevundimonas diminuta—the standard regulatory test organism for sterile-grade filtration. This test confirms that the membrane serves as a reliable biological wall against common spoilage bacteria and wild yeasts.

Can I integrity test these cartridges on-site?

Yes. Because the Hy-PureFB™ Pleated Membrane Filter series is a true membrane filter with a tightly controlled pore matrix, it can be easily integrity tested in the field before or after a production run. The cartridges support both standard Bubble Point and Forward Flow (Diffusion) testing protocols, allowing your quality assurance team to verify that the filter is intact and properly seated before launching a batch.

Does the Hy-PureFB™ line meet international safety and regulatory standards?

Absolutely. Consumer safety is top priority. All structural and filtration materials utilized in the assembly of the Hy-PureFB™ series meet FDA regulations for food contact under 21 CFR parts 170–199. Furthermore, the filter elements comply with European Commission Regulation (EU) No. 10/2011 and meet the strict requirements of the United States Pharmacopeia (USP Class VI) Plastics tests for extractables.

Can these filters handle repeated chemical washdowns and steam cycles?

Yes. The entire assembly—including the outer protective cage, inner support core, and endcaps—is thermally welded together without glues or resins that could degrade. This robust polyolefin structural cage enables the cartridge to withstand repeated Clean-In-Place (CIP) sanitation procedures, hot water flushes, and in-line steam sterilization cycles at temperatures up to 135°C (275°F).

What is the recommended change-out differential pressure?

We recommend replacing the cartridges when the differential pressure (ΔP) reaches 2.4 bard (35 psid). While the heavy-duty inner cores are built to withstand much higher pressures before structural deformation occurs, operating past 35 psid restricts flow rates, increases energy consumption, and places unnecessary mechanical stress on your process pump seals.
