Air Over Oil Presses
Our high performance air over oil presses are the result of over 75 years of precision design and proven engineering. These 2.5 ton – 50 ton hydropneumatic presses run on a shop air supply and utilize minimal hydraulic oil, making them perfect hydraulic press alternatives with lower upfront investment cost, higher efficiency and minimal maintenance.
More Efficient
Our air over oil presses are powered by compressed air and run only when cycling. With no hydraulic pumps or electric motors as well, these presses are far more efficient than comparable hydraulic presses.
Quieter
Hydraulic presses produce constant noise and heat, whereas air over oil presses produce no heat and emit noise only during the press cycle, resulting in a much quieter, more comfortable working environment.
Safer
Hydraulic presses require high voltage electricity and large oil reservoirs, increasing risk to your team. With no high voltage energy, minimal and/or self-contained oil, and quieter operation, our air-over-oil presses are safer to operate.
Less Maintenance
Air over oil presses have fewer, less complex moving parts, requiring minimal maintenance to operate over their lifetime. They are also less expensive up front compared to hydraulic presses, providing you with a better, quicker ROI.
Air over oil presses, commonly referred to as hydropneumatic presses, are a great fit when you are looking for the reliability and efficiency of an air press but need the increased force typically offered in hydraulic presses. Our hydropneumatic air over oil presses use air as an energy efficient power source to intensify hydraulic oil and deliver up to 50 tons of force without the use of pumps, motors or high-voltage electricity. There are many benefits to air over oil presses as hydraulic press alternatives.
Some of the benefits of an air over oil press versus a full hydraulic press include:
- Reduced initial purchase cost
- Reduced long-term maintenance cost
- Reduced factory noise
- Improved safety due to the lack of high voltage power
- Ability to deliver force equivalent to many fully hydraulic factory presses
- Base models simply require a factory supplied airline to operate
