Pneumatic power systems comprise any sort of mechanised or automated process or apparatus that uses pressurised gas or compressed air to drive motion. Hydraulic systems are an apparent counter-reference here, in which motion is driven by fluid held under identical compression forces within a sealed system.
The term ‘pneumatic’ refers to the delivery of power by the controlled movement of pressurized gases (including air). The pressurised gases that power the requisite mechanisms are often transferred to where they are needed by an airtight network of hard pipes, sturdy hoses, or lengths of flexible tubing in any pneumatic-powered system.
A large range of pneumatic fittings, couplings, valves, and adaptors connect the vast majority of these conduits to one another and to the numerous devices being powered. A pneumatic fitting is any sort of connector meant to connect components or devices in a sealed and pressurized dry-air system.
Today, these systems and fittings are widely utilized in a wide range of sectors and applications, including construction, assembly, and production line setups, as well as a wide range of industrial machines, handheld tools, and workbench equipment. In many professional contexts, the power delivered by a pneumatic system is more versatile, reliable, cost-effective, and safe than an equal configuration powered by multiple electric motors and actuators.
