High dirt capacity pleated polypropylene filters

Pall Particulate Filters

These High dirt capacity pleated polypropylene filters constructed with a proprietary technique such as varying the fiber diameter instantaneously and continuously to produce a pore-size distribution from coarse (upstream) to fine (downstream) while maintaining constant void-volume throughout the depth of the filter medium. This unique construction means that more contaminants are trapped in the outer and inner layers of the medium, resulting in the substantially increasing dirt-holding capacity, and the service life of the filter.
