01

PPI selection for particle size

Pore size sets the particle range a reticulated pre-filter captures. Lower PPI loads more dust before pressure rises; higher PPI captures finer particles.

02

Pressure drop vs PPI

Air permeability is measured per ISO 7231 for each grade. Pressure drop at a given face velocity rises with PPI and thickness.
