Versaflex Series HE

Summary

Product Identification

The Versaflex High Efficiency (HE) Meltblown Cartridges are industrial filter cartridges designed for maximum process compatibility. They feature a thermally-bonded, glue-free design with a graded density matrix to trap dirt, providing longer life and better flow rates than standard cartridges.

These cartridges are made from 100% polypropylene using FDA-listed materials and a thermal-bonding process that seals the media to the endcaps, ensuring a bypass-free filter. They deliver high dirt-loading capabilities and superior performance compared to spun-bonded and stringwound cartridges.
