Hi Rotor Hi Rotor : Parker KURODA SH Series HRN Series PROA Series PRH Series PRNA Series PRHA Series PRN Series CRN Series Full series line-up A full line of 1, 3, 10, 20, 30, 50, 150, 300, 800 is available. For PRNA1 and bigger models, single and double vane type (with double the effective torque) are available. For PRN50 and bigger models, a series of specially made cushion units (CRN) are available. In addition, there are HI-PAL HI-ROTORs of PRHA10 and bigger (incorporating solenoid valve). ■ Durability to high temperature Use of dry air dehumidified through an air dryer makes it possible to use HI-ROTOR within a surrounding temperature range of -5℃~ 80℃. (PRN : Usable at a maximum of 60°C) ■ Outstanding durability A solid vane shaft and built-in damper are combined with a unique sealing mechanism to assure outstanding durability. PRN50 and bigger models are capable of operating a greater load with the incorporation of a Hydro-cushion. ■ Stable operation Uniquely designed sealing mechanism minimizes leakage, assuring low speed oscillating and stable, smooth operation at low pressures and speeds. ■ Easy-to-use oscillating angle Three oscillation reference points of 45° and 90° and five oscillating angles of 90°, 100°, 180°, 270° And 280° are featured. Oscillating angles that are frequently used are standardized for wide selection
