Description
PP Melt Blown Depth Filter Cartridge
The WIRES PP Melt Blown Filter Cartridge is manufactured from premium polypropylene using a melt-blowing process that produces dense, uniform pore structure and high filtration efficiency. Because particles become trapped by bridging within the pore network, even particles smaller than the nominal pore size are intercepted, achieving filtration efficiency above 98%. The cartridge has high self-cleanliness, minimizes water contamination, and resists acids, alkalis and organic solvents. Its robust construction maintains shape under pressure differentials up to 0.4 MPa.
Key Features
- Graded pore structure (inner fine, outer coarse) for true depth filtration
- Filtration efficiency ≥ 98% with particle-bridging effect in the melt-blown matrix
- High self-cleanliness — low extractables, suitable for food and high-purity water
- Resists acids, alkalis and organic solvents; no deformation at 0.4 MPa pressure drop
- One-piece construction from pure polypropylene — no binders or adhesives
