Air compressors use pressurized air to power tools. While sanding, drilling, or painting tools are common applications, really there is almost no limit to the versatility of the air compressor.
The primary components of a compressor are the piston and cylinder. The suction stroke draws air in through the inlet valve. In the discharge stroke, trapped air is compressed as the piston moves down, and then released through a discharge valve into a tank. A motor drives the piston arm.
As air is forced into the tank, it becomes pressurized. The pressurized air functions like a battery. Its stored energy is used to run power tools such as sanders, paint sprayers, or drills.
