The Process Filtration Division of Parker Hannifin has launched a range of high performance filter cartridges, designed to help plant and process engineers make significant reductions in the installation, maintenance and operating costs of filtration systems. 

Called ParMax, the new large diameter filter cartridges offer exceptionally high levels of dirt retention combined with long filter life; perhaps as importantly, the design of new filters means that a single cartridge can be used to replace up to 10 conventional units.

The ParMax filter cartridge has been designed to be a direct replacement to the Pall Ultipleat HFU cartridge.

ParMax combines inside to outside flow with a pleated filter layer, which will allow cleaner changes and a considerable reduction in the carry over of contamination, giving a much longer operating life than can be expected with conventional elements. This extended operating life means less downtime as filters do not need to be changed as frequently.

In addition, a ParMax cartridge 6-in diameter and 60-in in length can typically handle flows of 114m3 per hour, with a single Parker cartridge being able to replace up to 10 traditional 2.5-in by 40-in filter units.  This again reduces operating costs, as change-out times can be cut by a factor of ten, and minimises the initial investment, leading to a significant fall in the overall cost of ownership.

The high flow filter elements feature a layered construction providing excellent retention across a wide range of flux rates.

The cartridges are available in polypropylene and microfibre glass media with absolute (99.98percent) micro ratings from 1 to 90microns.

The polypropylene filter combines pleated and depth media, with a graded density layer for exceptional levels of filtration, while the microfibre glass version enhances flow due to its hydrophilic properties.

The ParMax cartridges are suitable for use in make up water and flush water systems in the metalworking, power generation, process water, chemical processing/petrochemical, and food and beverage industries, with all materials used being acceptable for potable and edible contact.
