Hydra-pneumatics improves quality and reduces costs.  One major appeal to the hydra-pneumatic unit is its simplicity-operating like an air cylinder, but with fluid.

• Hydra-pneumatics is a low-cost press solution that can replace hydraulic or even mechanical devices. Achieving high forces with speeds associated with compressed air is the basic principle described further in this article.
• Costs reduced or eliminated—heat, pump noise, space requirements, maintenance, safety issues, leaks, energy consumption, environmental disposal and cycle time—are some of the key benefits of hydra-pneumatics.
• Quality improvement is realized inherently in the operating principle of Aries’ units. However, where quality must be verified and recorded in critical assemblies, Aries doesn’t stop at the working unit.
• Intensification occurs when air is applied to a piston attached to the high-pressure rod, and the rod enters into the trapped fluid behind the work piston. Here, the process becomes hydraulic.
• In a high-cycle environment, air-oil separation is one key characteristic separating today’s hydra-pneumatic units from yesteryear’s. Modern seal technology and unique venting methods can mean millions of trouble-free cycles.
