Mesh Bag Filters

For removal of solid non-deformable particles 

Untitled design-8

Mesh filter bags serve as a barrier against solid particles that could potentially disrupt downstream processes within a filtration system. Operating on the principle of surface filtration, like a sieve, effectively capturing particles larger than the pore size of the media, provided these particles are solid and non-deformable. The mesh filter bag design and construction ensures that there is zero risk of fibre migration from the filter, thus preventing any additional contamination of the liquid passing through it. Available Mesh filter bags options:

  1. Monofilament Meshes: These meshes feature a tightly woven structure of single filaments with an absolute micron rating. Manufactured under food-safe and silicone-free conditions.

  2. Multifilament Meshes: Comprising multiple filaments twisted together and woven into a nominal rated mesh structure. Multifilament meshes are suitable for non-critical applications.
