Pneumatics (from Greek πνεῦμα pneuma "wind, breath") is the branch of engineering that uses gas or compressed air.Pneumatic systems used in industry are usually powered by compressed air or compressed inert gas. A centrally located electric compressor powers cylinders, air motors, pneumatic actuator

• Simplicity of Design and Control - Machines can be easily designed using standard cylinders and other components and operated with simple on-off controls.• Reliability—Pneumatic systems typically have a long life and require little maintenance. Since the gas is compressible, the

Heating, ventilation, and air conditioning (HVAC)[1] is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engi
