Ultipleat® High Flow Filter For Etchant Applications

The Ultipleat High Flow Filter is designed for TFT LCD liquid applications, such as wet etching and cleaning. Its large diameter, inside out flow path and unique, high area, pleated construction allow for a long service life.1The filter is very economical due to its high flow capacity. Far fewer filters are thus required, compared to standard size cartridges.

1 Service life is dependent upon chemical compatibility and temperature.

Features and Benefits

  • Large filter diameter, 152 mm / 6.3 in. nominal, equates to fewer cartridges and smaller housing footprint
  • Easy filter change-out
  • 249 mm / 9.8 in. and 526 mm / 20.7 in. lengths available
  • High area pleated construction for low differential pressure and high dirt capacity
  • PTFE and ECTFE medium for excellent etchant compatibility
  • Long service life
  • Inside out flow pattern further enables high flow rates

Pressure Drop vs. Liquid Flow Rate1

Pressure Drop vs. Liquid Flow Rate
1 For liquids with viscosity differing from water, multiply the pressure drop by the viscosity in centipoise.

Since etchants can vary significantly, it is recommended that the filter be tested for compatibility at the service temperature to ensure long service life.
