The manufacturing of the Twin Filter absolute (standard 65.5mm) cartridge has undergone a rigorous change. Now the fully thermal welded construction ensures safe usage in filtration with high temperature fl uids, acids, diesel, oily water and solvents. Furthermore our cartridge now has a fi rm outer-guard making it much stronger. The TH absolute rated filter cartridge is manufactured under high quality standards in our production facilities in the Netherlands. This high performance and cost effective pleated cartridge is especially manufactured for fi ltration of oilfi eld fluids. The TH cartridges assure the removal of particles in the size range, necessary to protect the formation. The pleated absolute cartridges have a diameter of 2 ½" (65.5mm), and the 6 ⅝" (168.28mm) high flow Magnum cartridge.
