Common Pneumatic Devices

A pneumatic device is a tool or instrument that generates and utilizes compressed air. There are many different types of pneumatic devices. They can be divided into two categories: rotor and reciprocating piston. Some examples of pneumatic devices are rock drills, pavement breakers, riveters, forging presses, paint sprayers, blast cleaners, and atomizers.

An air compressor is one of the major types of pneumatic devices. They are power-driven machines that compress air from initial intake pressure to a higher pressure. Air compressors are divided into two different classifications: the positive-displacement type and the velocity type.

A reciprocating-piston compressor is another type of pneumatic device. This kind of device operates in reverse and also serves as a motor. Compressed air enters the cylinder and then it expands and forces the piston to move.

Pneumatic tools can also come in portable form. Some examples of portable pneumatic tools are wrenches, drills, reamers, stud setters, tappers, nutsetters, impact tools, tappers, and shears. Abrasive devices, such as grinders, buffers, and sanders, are also portable pneumatic tools. The operating speeds of these tools can be changed by throttling the air to the motor.

Chipping hammers and air hoists are two more types of pneumatic devices. Chipping hammers are a pneumatic valve type of tool that has a separate mechanism to control the airflow to the piston.

Pneumatic counters sinking tools are also pneumatic devices. They are classified as portable specialty tools. Other types of mobile specialty tools are concrete vibrators, valve grinders, shank grinders, air cranking motors, and paint mixers.
