Rethinking filtration: with BECO® Helix depth filter cartridges, Eaton's Filtration Division introduces a completely new approach to liquid filtration. These innovative depth filter cartridges provide a double depth filtration effect, significantly higher particle-holding capacity, and a longer service-life compared to other pleated depth filter cartridges. This performance is made possible by the unique helix wrapping of the pleated polypropylene (PP) fleece layers.

The innovative structure and the graduated, thin fleece layers from coarse to fine, maximize the filter surface area and allow optimal flow with low pressure differentials. The funnel effect and high mechanical stability of the graduated fleece layers make BECO Helix depth filter cartridges excellent for backwashing. The fine fleece layers provide reliable separation in particle, clarifying, and fine filtration, while also protecting downstream membrane filter cartridges.

Available in various lengths, with all common adapter designs and gasket materials, the BECO Helix depth filter cartridges ensure safe use across a variety of different applications and filter housings. The depth filter cartridges have a filter area of 0.7 square meters per 10-inch element, they are available with retention rates from 0.6 to 10.0 µm, and are available immediately.

"The BECO Helix depth filter cartridge with a retention rate of 0.6 µm was specifically designed for bottling processes in the beverage industry. It protects downstream membrane filters from clogging substances and significantly extends their service-life, provided the regeneration and sterilization instructions are properly followed," explains Elke Brandscheid, Team Leader Technical Service & Product Manager Filter Cartridges of Eaton's Filtration Division. The CIP and SIP capability (Clean-in-Place and Sterilize-in-Place) of the BECO Helix depth filter cartridges also makes them well-suited for this application, while their backwashability, even with hot water, further extends the service-life and reduces operating costs.

All BECO Helix depth filter cartridges provide a beta ratio of ≥ 5,000 or a retention efficiency of ≥ 99.98%. These food-grade depth filter cartridges have been carefully developed through extensive research, drawing on Eaton’s long-standing expertise in filtration for industries such as food & beverage, cosmetics, and fine chemicals. The innovative design of the BECO Helix depth filter cartridges enables optimized filtration with extended service life, reduced operating costs, and more sustainable material use.
