The air flow is regulated by manual or automatic solenoid valves and the pneumatic cylinder transfers energy provided by the compressed gas to mechanical energy. ![]() The compressed air is supplied by the compressor and transmitted through a series of hoses. The system consists of interconnected set of components including a gas compressor, transition lines, air tanks, hoses, standard cylinders, and gas (atmosphere). Pneumatic systems are commonly powered by compressed air or inert gases. The field of pneumatics has changed from small handheld devices to large machines that serve different functions. Pneumatics is a branch of engineering that makes use of pressurized gas or air to affect mechanical motion based on the working principles of fluid dynamics and pressure. The load or the force that you need to apply, the output speed, and energy costs determine the type of system you need for your application. This article will help you make a better choice for your application by describing the two types of systems, their applications, advantages, and disadvantages. Neither type of system is more popular than the other because their applications are specialized. ![]() Pneumatics use an easily compressible gas such as air or other sorts of suitable pure gas-while hydraulics uses relatively incompressible liquid media such as hydraulic or mineral oil, ethylene glycol, water, or high temperature fire-resistant fluids. The biggest difference between the two types of systems is the medium used and applications. They each use a pump as an actuator, are controlled by valves, and use fluids to transmit mechanical energy. Both pneumatics and hydraulics are applications of fluid power. Pneumatic and hydraulic systems have many similarities. The rugged nature and general low cost of compressed air products for these applications as well as the extremely low level of maintenance required have become more important criteria where downtime and maintenance costs have also risen dramatically especially when compared to more complex and expensive capital cost alternatives. Part of pneumatic technology is the use of compressed air for blowing, moving and cooling. Pneumatics plays a very large part in both automation and packaging as outlined below in the blog Packaging solutions and advances have also become important. With the advent of the Covid 19 pandemic, there has been an acceleration toward automation.
