Qualipoche F

Felt bag

  • 1 - 200 µm

Prefiltration or clarification felt bag, guaranteeing an economical nominal filtration.

An economical felt bag

QUALIPOCHE F bags are made from fibers that allow for decreasing porosity. The needle felt provides the bag with a good retention capacity for minimal pressure drop. The surface of the felt retains coarse impurities and its internal structure ensures retention of finer particles.

The wide range of filter materials offers excellent chemical compatibility for a variety of industrial applications. The bags are also available in a thicker version (PP and Polyester) which significantly increases performance and service life.

QUALIPOCHE F bags are available in a wide range of lengths, diameters and rings, allowing easy adaptation to most industrial standards.
