LOFPLEAT-HE

Summary

Product identification

The LOFPLEAT™HE Series are high-efficiency polypropylene filter cartridges. They feature multi-layer melt-blown polypropylene media, designed for high flow rates with low differential pressure. This design provides ideal depth filtration characteristics for a wide range of applications.

Key features include:

• Retentions from 0.1 to 10 microns
• Acceptable for food and beverage applications
• Meets USP Class VI biological tests for plastics
• Filtration efficiency of 95%
• Eliminates dirt unloading at high differential pressure due to fixed pore structure
• High dirt holding capability with multi-layer, graded pore design
• Polypropylene construction compatible with a broad range of system liquids

Suggested applications include: food & beverage, RO prefilters, DE trap, aqueous solutions, chemicals, photoresists, pharmaceuticals, cosmetics, ultrapure water, and ink.
