Pneumatic systems are used extensively in industrial automation and are usually powered by compressed air. Pneumatic systems use actuators such as cylinders that are typically controlled via solenoid valves, and are used when they can provide a lower cost, more flexible, or safer alternative to electric actuators.

Often regarded as the fourth utility after electricity, natural gas and water, compressed air is widely used in manufacturing facilities. Basic pneumatic components such as valves, cylinders, hoses and fittings can be combined in many ways to provide simple and reliable machine control. Pneumatic power transmission is often the best way to grip, lift, press, shift or stack products. With the addition of some passive or adaptive control - as simple as a regulator in many cases - applications such as tensioning, crimping, cutting and labeling are feasible and practical.
Guide to Pneumatic System design
Pneumatic Air Preparation
(FRL- Filters, Regulators, Lubricators)
Pneumatic air filters, pneumatic pressure regulators, air lubricators, air relief valves and soft-start valves are available in a wide variety of port sizes to meet a broad range of pneumatic air supply filtration, air regulation and compressed air lubrication applications. The modular design allows stand-alone applications and also enables easy field assembly for combining pneumatic filters, pneumatic pressure regulators, air lubricators, and air relief valves (Using modular assembly brackets which must be purchased separately).
