Pneumatics, faster, offers rapid movement of cylinders at smaller size due to air compressor flow rates which flow quickly with little resistance. Medium Hydraulics — liquids, oil, water or a mixture Pneumatics — Gas, usually air. Speed Hydraulics — Slower, more complicated larger systems Pneumatics — Faster, simpler and quicker. Cost Hydraulics — Expensive — more complex and larger Pneumatics — Cheap — no reservoir needed for storage. Pressure Hydraulics — Utilises around to psi up to psi Pneumatics — Utilises around psi up to psi.

Do you know what the difference is and does it matter? Find out why it matters and when you would use tube or pipe by reading this article. There are a number of different sizing standards used throughout the world. Do you know which one you should use and what the difference is between them? Most differences between these two systems stem from the fact that hydraulic systems use liquids, which do not compress, and pneumatic systems use gasses, which do.
These affect the way the systems function and are built, as well as their capabilities and applications in the field. In a nutshell, hydraulic systems are bigger and slower, but provide higher precision and more power, whereas pneumatic systems are better suited for applications requiring quicker, more compact systems with lesser force and precision. Hydraulics rely on oil or water to transfer pressure applied at one point to another point.
They can use anything from mineral oil to ethylene glycol to synthetic liquids to water. Thanks to the need to pump fluids hydraulic systems generally include reservoir tanks. These systems are usually more heavily built and take up more space, but they are also quite powerful. They typically operate from 1,, psi, and specialized systems can operate at 10, psi or more.
Machine noise levels are going to be substantially reduced, uptime for all machines increased, and back up pumps will be available in case a working pump breaks down. In terms of housekeeping, pneumatic systems are easier to maintain in comparison to their hydraulic counterparts. Air-operated circuits are cleaner as its force transmitter is atmospheric air. Any leaks will not cause problems. However, this can be quite expensive and it will take about five compressor horsepower to provide air to a typical handheld blow-off nozzle then maintain psi.
Thus, even if hydraulics housekeeping can be a problem, proper measures just needs to be employed to remedy the issue. Appropriate plumbing procedures, preventive maintenance, and the right materials can help minimise hydraulic leaks.
Pneumatics are typically used in factory set ups, construction, mills, building, and technology by using a central source of compressed-air for power. Medical applications of pneumatics are likewise common including the high-powered drill of a dentist. Practically everything could run on pneumatics including any form of transportation. Further system modifications can increase the precision with which a pneumatic system operates, enabling applications that require labeling, cutting, crimping, or embossing.
Due to their durability, superior performance, and ability to supply energy to actuators at high speed, pneumatic systems remain among the most reliable choice for powering everything from commuter transit systems and natural gas extraction to agtech devices that can milk a cow autonomously.

The Advantages and Disadvantages of Hydraulic Systems Since hydraulic oil is only compressed by approximately 0. How Pneumatic Systems Work Pneumatic systems operate in much of the same way as hydraulic systems do. Why Pneumatic Systems Beat Out Hydraulic Systems While hydraulic systems may guarantee fewer energy losses during operation, in general, pneumatic systems ensure a lower up-front cost, fewer maintenance demands, greater durability, and a higher degree of mechanical reliability, making them the most cost-effective option in the long-run.
