Extruded polypropylene cartridge

  • 0,5 - 100 µm

Depth filtration cartridge manufactured from extruded polypropylene fibers to obtain a decreasing porosity. This density gradient gives the cartridge excellent retention capacity and minimal pressure drop. Their 100% polypropylene design ensures excellent chemical compatibility for industrial applications and are perfectly suited for food applications. Wide range of lengths, diameters and end caps available.

A very wide range

QUALITHERM™ cartridges are available in many lengths from 5 to 40 ” (custom made on request) and two diameters: Ø64 or Ø110 mm.
Each cartridge size can be ordered over a porosity range between 0.5 and 100 µm.

High performance and economical

The 100% polypropylene coreless monoblock construction ensures excellent chemical compatibility. Extruded fibers provide decreasing porosity, limiting pressure drop, and high retention capacity.
