Polypropylene Nominal Pre filters

Applications

Polypropylene Nominal Prefilters

Composed of polypropylene fibers with nominal pore size rating

Recommended for prefiltering aqueous, acid, and solvent solutions

Final filtration step to remove large particles

Nominal Pore Size Rating (µm)¹	Thickness (µm)	Frazier Air Permeability (L/sec·m² at 200Pa)	Water Bubble Point (psi)
0.2	170	3.7	15.4
0.45	200	9.4	11.5
10	152	49	0.5

¹ Polypropylene nominal prefilters are not intended for microbial retention.
