IntegraPac™ IP-51 UF Membrane for Beer Filtration DuPont Equivalent

Product Introduction

LEFILTER's IntegraPac™ IP-51 UF Membrane is a robust and compact ultrafiltration solution tailored for beer filtration, specifically engineered as an equivalent to the renowned DuPont system. Designed for breweries seeking high clarity, microbial stability, and process consistency, this membrane element offers a cost-effective alternative that doesn’t compromise on quality or performance.

Its integrated, modular design allows for space-saving installation while maintaining reliable flow and long-term service life. Developed using advanced hollow fiber technology, this UF module effectively removes yeast, bacteria, and haze-causing particulates from beer without affecting its flavor, color, or aroma profile. It is well-suited for large-scale brewing operations as well as craft and specialty producers aiming for clear, shelf-stable beer.

Whether you're filtering lagers, ales, or unfiltered specialties, this DuPont-compatible membrane provides a dependable approach to achieving consistent product quality and optimizing downstream processing.

Application Areas

LEFILTER's IP-51 UF Membrane equivalent is a valuable component in modern brewing facilities. Its ultrafiltration capabilities help enhance clarity, extend shelf life, and reduce dependence on traditional filtration aids such as diatomaceous earth. Key applications include:

Cold Stabilization: Effective removal of haze-forming proteins and colloids, allowing beers to maintain visual clarity even at low temperatures.

Microbial Reduction: Filters out spoilage organisms such as Brettanomyces, Lactobacillus, and Pediococcus, reducing the need for pasteurization.

Final Filtration before Packaging: Ensures stable, particulate-free beer entering bottles or kegs, minimizing re-fermentation or turbidity issues.

Keg and Tank Clarification: Enables breweries to reuse tanks faster by accelerating clarification without additives.

Specialty Beer Production: Ideal for high-end, unpasteurized beers where maintaining flavor integrity is essential while meeting safety and clarity standards.

The IP-51 equivalent membrane maintains optimal permeate flow and resists fouling, making it a reliable choice for breweries with high turnover and strict hygiene protocols.

FAQ:

Q:Is the IP-51 equivalent membrane suitable for unfiltered or hazy-style beers?

A:Yes, this membrane supports haze control without stripping desirable turbidity or mouthfeel. It can be used selectively depending on haze stability requirements.

Q: What cleaning method is recommended for long-term membrane integrity?

A: A CIP routine using alkaline and acidic cleaning agents within the prescribed pH range (2–10) ensures durability and efficient recovery of flow rates.
