ALpHA®
An advanced 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.
