Air to Hydraulic Power Converters

Power a hydraulic cylinder from your air system to avoid the setup, cost, and mess of hydraulic fluid. These converters give you more consistent power than using air power for an air cylinder. However, because air works at a lower pressure than hydraulic fluid, your hydraulic cylinder won’t move loads at its full force. Attach these converters to an air line with a speed controller and solenoid (not included).
Note: These converters are not for use near fire.
