Hydroline HFR – Inline Heavy Duty Filter
The Hydroline HFR is a medium-pressure inline filter built for return and suction line duty in industrial and mobile hydraulic systems. Aluminium die-cast housing in three frame sizes keeps flows to 150 LPM clean across a wide range of port sizes and filtration grades.
