Hydac HF4RL Series Medium Pressure Filters
- Inlet/Outlet port options include SAE straight thread O-ring boss, and 1 1/2″ SAE 4-bolt flange to allow easy installation without costly adapters.
- Choice of Nitrile or Fluoro Rubber seal material provides compatibility with petroleum oils, and most synthetic fluids, water-glycols, oil/water emulsions, and water base fluids.
- Screw-in cap mounted on top of the filter bowl allows quick and easy element changeout.
- To allow fluid to be drained from the filter before changing the element, a vent plug and a drain plug are provided. Element changes can be made with no mess and minimal loss of fluid.
- Clogging indicators, with and without thermal lockout, are magnetically actuated and have no external dynamic seal. High reliability is achieved and magnetic actuation eliminates leakage.
- A cartridge type bypass valve (optional) is mounted in-line between the inlet and outlet port to provide positive sealing during normal operation and fast response during cold starts and flow surges.
