Ultipleat® High Flow Filters

The Ultipleat^® High Flow filter is suited for applications such as cooling water, pre-RO, and resin trap filtration. It is a large diameter, coreless, single open-ended, pleated cartridge with an inside to outside flow pattern. The filter's unique crescent-shaped pleat geometry, combined with its large 152 mm / 6 in diameter, reduces the number of filters and size of housing required. The cartridge is also available in a wide range of Pall media types for other applications.

• Up to 50% smaller filter system possible
• Up to forty times fewer elements to change out
• Very high flow rates per filter cartridge, up to 500 gpm / 114 m³/hr
• Available in 508 mm / 20 in., 1016 mm / 40 in. and 1524 mm / 60 in. lengths
• Coreless construction to minimize waste disposal
• Absolute rated filter medium for reproducible performance
• Inside to outside flow configuration - all contaminants held within the single open ended filter

¹ The test procedure used is an adaptation of ISO 4572, modified to determine the micron size above which particles are quantitatively removed.
² Pressure drop in psid per US gpm and mbar per cubic meter per hour for the cartridge length shown. Multiply this value by the total system flow to determine the aqueous pressure drop. Next 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 due to the Ultipleat® High Flow filter housing.
