PreFil APKM Cartridge

APKM - Absolute multi-layered PP Cartridge

Brand PreFil
Media: Liquids
Micron Ratings: 0.2 to 70 µm
Filter Type: Pleated Media

Masterfilter APKM series absolute multi-layered polypropylene cartridges combines depth filter technology with pleated filter technology, ensure high contaminant holding capacity and large filtration area. APKM construction adopts depth filter technology of graded pore-size avoiding filter surface jam. Graded pore-size distribution from coarse (upstream) to fine (downstream) can remove particles, colloids and gels gradually and extend filter’s service life.

Features Benefits

  • High contaminant holding capacity
  • Graded pore-size (5 to 7 PP layers) provides excellent flow rate and long service life
  • Absolute rating from 0.2 to 70 microns
  • Efficiency: 99.98%
  • Low pressure drop
  • 100% PP offers compatibility with most chemicals, solvents caustic and acids
