BECO Helix depth filter cartridges are characterized by their exceptionally long service-life compared to other pleated depth filter cartridges. Their unique helix-wrapped pleated polypropylene fleece layers maximize the filter surface area, providing a high flow rate with low pressure differences.

The gradation of the thin fleece layers from coarse to fine offers twice the depth filter effect and a significantly higher particle holding capacity than standard pleated depth filter cartridges. Additionally, the funnel effect of the graduated fleece layers allows for excellent backwashing of the BECO Helix depth filter cartridges.
