Pneumatic cylinders are the final component in a pneumatic or compressed air control or power system. Pneumatic cylinders, also referred to as air cylinders, are devices that convert compressed air power into mechanical energy.

Pneumatic systems are used to push, pull, lift and open/close doors in material handling and processing. They can also hold, remove and position materials or pieces for manufacturing. 

 Using pneumatic systems is economical and environmentally friendly, as air is inexpensive, plentiful and easily compressed and stored in tanks. Exhaust air can also be returned to the atmosphere.
