HPK05 Series – High Pressure/High Flow

The HPK05 high pressure filter series is made of ductile iron and steel for strength and durability. Machined by-pass valves are case-hardened at critical points to provide maximum strength and reliability. Reverse flow by-pass valve allows bi-directional flow through the filter head, with head-up or head-down mounting capabilities.

Benefits:

  • Rugged construction for reliable performance – ductile iron and steel for strength and reliability
  • Featuring our high-performance DT filters with multiple efficiency options – allowing you to achieve the performance you need for most any application
