334 head PP-absolute pleated filter element

Type:Filter Products

Brief:334 heads / Polypropylene (PP for short)


Product Description

Polypropylene (PP) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to a variety of organic solvents and acid and alkali corrosion. It has a wide range of applications in industry.

It is composed of spray-melted ultra-fine PP fiber filter cloth with different fiber precision, and is formed in the PP inner and outer sleeve in a special folding method. Its filter area is much larger than the general deep-layer filter element by about 10 times or more; and has a low pressure difference, The characteristics of large flow, high impurity capacity and long service life are generally used in liquid clarification filtration or membrane filter pre-filtration.

Product Features
  • Low pressure loss, high dirt holding capacity and long service life.
  • The end caps or joints are combined by high-strength PP hot-melt method without adding any adhesive.
  • The product is manufactured in a clean room with high cleanliness.
  • This product can be cleaned with 18 M ohm ultrapure water, and the TOC is lower than 40 ppb.
