Absolute Rated Heavy Duty Filter Bag – MFB Series

High Dirt Loading | 99% Efficiency | Alternative to FSI POMF Series

Product Overview

The CMI MFB Series Absolute Rated Heavy Duty Filter Bags are designed for applications requiring high filtration efficiency, long service life, and heavy dirt-loading capability.

Constructed with multiple layers of melt-blown polypropylene microfiber, the MFB Series provides absolute-rated performance up to 99% efficiency, making it an excellent and cost-effective alternative to pleated cartridges.
