ALpHA® Polypropylene Microfiber

An advanced all-polypropylene microfiber filter with absolute ratings and extremely consistent filtration performance.

ALpHA® filter cartridges are absolute rated depth type filters constructed of 100% polypropylene (PP). They contain a graded density PP microfiber filter medium that provides a tapered pore structure. ALpHA® filters deliver superior flow rates and high throughput, with absolute submicron particulate retention and high dirt holding capacity. Their all-polypropylene construction provides broad chemical compatibility and low extractable levels in a wide range of fluids and applications.
