Pneumatics is that the field handling the tools and applications supported pressurized air or gases. Pneumatic tools, machines and systems differ from their electrical and hydraulic counterparts on the idea of the drive . While electrical tools work on electricity and hydraulic tools using pressurized liquids, pneumatic tools make use of compressed gas or gas. There are popular examples like pneumatic cylinder, sander, grinder, screw gun, nail gun and wrench that are widely used for domestic and industrial applications. the convenience of use and safety related to these tools make them extremely popular. Here are the sections discussing differing types of tools supported atmospheric pressure , along side the work mechanisms of every . Basic Working It is a well known incontrovertible fact that stored air or gases have P.E. which is converted into K.E. once they are compressed. compressed gas or gases attempt to expand, thereby forcing the piston to maneuver with an excellent
