Qualipoche MULTI

Multi-layer felt bag

  • 1 - 100 µm

Multi-layer filtration bag with extended service life.

Triple the life of your bags!

QUALIPOCHE™ MULTI pockets are made with multiple layers of polypropylene or polyester felt. The layering of the felts creates optimal degressive porosity. This construction allows a wider spectrum of particles to be retained within the thickness of the felt: increased depth filtration for delayed clogging. The external surface of the felt is flamed to avoid any release of fibers.
