Pneumo-Hydraulic Cylinder

The Inline “HPI” series cylinder provides a reduced overall cost and minimizes the footprint of the power unit within your application versus HPX and HPS. The “HPI” is a totally self-contained, single-piece power source ideally suited for a wide variety of Assembly and Forming applications using only two (2) pneumatic valves for operation. Available from 1-Ton to 200-Tons and up to 16.00″ stroke, and 2.00″ power stroke (depending on force required).
