Ultipleat® High Flow Filters

Features and Benefits: 

 

High flow rate per filter cartridge

• Up to 40 times fewer cartridges to change out
• Up to 50% smaller filter system possible

 

• Available in a variety of filter lengths and grades
• Absolute-rated filter medium for reproducible performance
• Features proprietary unique crescent-shaped pleat geometry
• Inside-to-outside flow pattern that traps contaminant inside the element, thus preventing polluting the treated water during the cartridge change-out
• Coreless large diameter cartridge, synthetic construction, to minimize waste disposal
• Handle for easy cartridge replacement
• Lower capital and installation costs
• Longer service life
• Consistent filtrate quality

 

These pleated high flow filters are available in the following variants – 

 

Ultipleat® High Flow 1 Micron Element: 

 

With its large 6.3 inch (16 cm) diameter, this filter allows you to use fewer filters to remove fine particles and cysts in high flow applications.

• Low cost of installation and filtration
• Fewer elements per change out
• 1 ®m absolute* filtration
• Polyethersulfone media provides greater than 3 log reduction® of Giardia oocysts and Cryptosporidium
• U-cup element seal ensures high-level removal efficiencies

 

*Particle removal rating 

 

Crescent-Shaped Pleat Geometry

 

Ultipleat® High Flow Filter Elements (1 µm) for Water Polishing Filtration:

 

These filter elements make use of polyethersulfone (PES) media with unique, laid-over pleat geometry. The filter's unique laid-over pleat geometry, combined with its large diameter, requires fewer elements for a given flow rate than standard diameter cartridges. Therefore, filter vessels are smaller, resulting in lower capital, installation costs, and reduced operating costs.

• Highly stable structure
• Media provides a typical 3 log reduction of Giardia cysts and Cryptosporidium oocysts
• Process reliability
• 10% water savings
• 30% lower operating costs
• Reduced installation footprint

 

Ultipleat® High Flow Filter for Etchant Applications:

 

This filter is designed for TFT LCD liquid applications like wet etching and cleaning. The filter’s large diameter, inside-out flow path, and unique, high area, and pleated construction provide long service life. The filter is more economical due to its high flow capacity. 

• Large filter diameter, 152 mm / 6.3 in. nominal, equates to fewer cartridges and a 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

 

Please note that the service life is dependent upon chemical compatibility and temperature. 

 

Ultipleat® High Flow Filter Elements with Profile® UP Media:

 

These pleated high flow filters are designed to withstand high flow rates up to 113 m3/hour (500 US gal/min) in a single 1524 mm (60 inch) cartridge. By utilizing Profile UP media with unique, laid-over pleat geometry, and a large diameter, fewer elements are required for a given flow rate than standard diameter cartridges. The filters feature a fixed fiber matrix and are free from surfactants and adhesives.

 

Ultipleat® High Flow XL Filters:

 

The spacing between the pleats within the Ultipleat XL filter has been optimized to deal with applications with moderate solids loadings.

• Higher flow rates per filter cartridge - up to 500 gpm (1900 lpm)
• Available in 20 inch (508 mm), 40 inch (1016 mm) and 60 inch (1524 mm) lengths
• Absolute rated filter medium for reproducible performance
• Polypropylene filters are made from all FDA listed materials
• Long service life in moderate solids loadings applications

Pressure Drop vs. Liquid Flow Rate¹

 

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.

⁴ Multiply this value by the total system flow to determine the aqueous pressure drop. For fluids other than water, multiply this value by the fluid’s viscosity at the operating temperature in centipoise. This value is the pressure drop across the Ultipleat High Flow filter(s) only; it must be added to the pressure drop contribution from the Ultipleat High Flow filter housing.
