PSE Cartridge L Type

A high flow rate type cartridge (1.5 times the flow rate of the conventional cartridges) has been added to the lineup of PSE cartridges that have been received favorably because of their high flow rate and high retention performance. Ready for use with larger LCD panels and wafers of larger diameters.

Overview

  • The flow rate is 1.5 times that of earlier cartridges.
  • The fine particle removal performance is rated for a single pass operation, standing at the same level as that of earlier PSE cartridges.
  • Long service life (Filtering service life is 1.5 - 2 times.*
  • Because the cartridge is the same size (φ70 mm) as earlier models, the housing does not requiring replacing.

Note

  • * The service life may vary with the conditions of use.

Features

  • High flow rate — The cartridge realizes a high flow rate equivalent to 1.5 times that of earlier (single (1-stage)) cartridges.
  • Excellent retention performance — The dense inner layer peculiar to the PSE membrane ensures reliable retention of fine particles.

  • Long service life — Owing to an increased filtering area, the cartridge has a long service life that is 1.5 - 2 times that of earlier cartridges.**

Note

  • ** The filtering service life may vary with the conditions of use.

Main applications

Since the cartridge employs the PSE membrane that has been received a favorable reputation, it is best suited for the following lines that require a high flow rate and high retention performance.

  • Filtration of purified water for cleaning equipment, etc. in the manufacturing processes of large LCDs and 300 mm wafers
  • Filtration of chemicals for cleaning equipment, etc. in the manufacturing processes of large LCDs and 300 mm wafers
