Air Over Oil Cylinders
Air-Hydraulics also offers a line of hydropneumatic intensifying cylinders which are an excellent choice for system and machine tool integrators. These air-over-oil cylinders present a cleaner and more resourceful means of power for assembly machine design with less restriction on design standards versus standard hydraulic cylinders.
High Energy Efficiency
By operating on standard compressed shop air and only consuming energy when actively cycling, hydropneumatic cylinders eliminate the idle waste of continuously running hydraulic pumps or electric motors. This on-demand power model drastically cuts utility costs while maintaining high performance.
Quieter & Cleaner Operation
Unlike traditional hydraulic units that whine and generate heat constantly, air-over-oil systems only emit sound during the actual power stroke and produce virtually no operational heat. Furthermore, their self-contained oil design removes the mess, maintenance, and complexity of leaky external hydraulic plumbing.
Enhanced Workplace Safety
Relying on pneumatics for primary power eliminates the need for high-voltage electrical setups at the workstation, reducing shock hazards. Additionally, the self-contained oil configuration removes the safety, fire, and environmental risks associated with large, pressurized hydraulic oil reservoirs.
Low Maintenance & Superior ROI
With fewer complex moving parts, these cylinders experience significantly less wear and tear, requiring minimal maintenance over their operational lifetime. They also require a much lower upfront investment than full hydraulic setups while still delivering heavy-duty force capacities up to 50 tons, ensuring a rapid return on investment.
Whether you are engineering a new production press from scratch or retrofitting a high-force booster into an existing pneumatic setup, hydropneumatic cylinders deliver heavy-duty hydraulic muscle without the traditional mess and overhead costs. Operating strictly on on-demand shop air, these self-contained units provide up to 50 tons of precise force while keeping your factory floor quieter, safer, and significantly more energy-efficient.
Our Hydropneumatic Air Over Oil Cylinders
Air Hydraulics offers two lines and 10 different models of air over oil presses for industrial, manufacturing environments. The C-Series and AH-Series serve as superior alternatives to a hydraulic press for many assembly and production applications. Depending on your needs, we have options ranging from 2.5 tons of force up to 50 tons of force.
