Puritech Ultraflow-K, the Retrofit of Parker High Flow Filter Cartridges

Puritech Ultraflow-K High Flow Filter Cartridge is the retrofit of Parker High Flow Filter Cartridges configured two types of end connectors: single O-ring end connector and double O-ring end connector for replacing Parker Megaflow old and new models perfectly. Pleated construction with outside to inside flow direction provides maximum flow rates with the lowest possible pressure drop, larger filtration area and longer service life. But with retrofit hard outer cage, it can stand higher pressure than the original Parker flexible netting cage. Puritech aims to offer cost effectly filter cartridges with satisfied quality to our valued clients, so Puritech Ultraflow-K High Flow Filter Cartridge is quite an ideal option for you.

Features and Benefits:

  • Higher flow rate. Under the same conditions, the flow rate of one 6-inch high flow filter cartridge is 10 to 15 times higher than standard 2.5-inch diameter depth filter cartridge
  • Thermally bonded multi-layer of 100% polypropylene filter media and support material for wide chemical compatibility and filtration integrity
  • Graded filtration pore sizes assure the high retention rate and long service life
  • Multi-layer pleated construction for lower pressure drop, higher dirt-holding capacity and inner O-ring sealing assures filtration integrity
  • Larger filtration area requires fewer filter elements to lower operation &maintenance cost and friendly handle design for easier change-out to reduce labor cost.
