PPE Cartridge

For prefiltration as well as clarification and filtration of ultra-pure water, various types of solvents, chemicals, process gases, etc.
AstroPore PPE Cartridges meet the needs of a wide range of fields including the chemical industry, electronics industry, pharmaceuticals & cosmetics industries, food industry, and others.

Overview

AstroPore PPE Cartridges demonstrate excellent performance in prefiltration, clarification and filtration of aqueous and non-aqueous liquids, and gases.

The AstroPore PPE Cartridge demonstrates excellent prefiltration, clarification and filtration performance.
Made of polypropylene that has excellent chemical resistance, the cartridge demonstrates its power in prefiltration, clarification and filtration targeted at removing not only acids, alkalis and various types of chemicals, photoresists and solvents but also fine particles such as airborne dust, various types of gases, and more.

Features

  • Excellent clarification and filtration — A dense non-woven fabric membrane performs reliable clarification and filtration. Also, since the membrane is made of polypropylene, it demonstrates a high effect in the removal of fine particles in gases as well.
  • Excellent prefiltration — The cartridge fully demonstrates the prefiltration function of the membrane filter by reliably retaining contaminants. It is very effective at prolonging the service life of filtration systems.
  • Excellent chemical resistance — Since all the cartridge materials are made of polypropylene, they have excellent chemical resistance and can be used in acids, alkalis and various types of organic solvents.
  • Inert and safe materials — The filter material and the materials of constituent parts of the cartridge are made of inert materials and produce little effluent, and are safe from a biological viewpoint as well.
  • A wide variety to choose from — A wide variety of shapes are available that fit various types of housings.

Precautions for use

  • For filtration operation, the cartridge should be used at no more than the specified pressure.
    1. In the positive pressure direction, the cartridge should be used at a differential pressure of 0.49 MPa or less (at normal temperature).
    2. Do not apply pressure in the reverse direction. Exercise sufficient caution especially when using the “without guard” type.
  • For filtration operation, the cartridge should be used at no more than the specified temperature. In the case of use at 80℃, the operation pressure (positive pressure) should be 0.20 MPa or below.
  • All the constituent parts are made of polypropylene and have excellent chemical resistance, but before actual use, the chemical resistance of the cartridge should be checked under the planned conditions of use.
  • After setting the cartridge, the filtration system should be flushed with the proper fluid according to the purpose of use.
