A piston compressor is a type of mechanical device that compresses air or gas using a piston. It operates by drawing in air through an inlet valve, then compressing it within a cylinder as the piston moves. This process increases the pressure of the air, making it suitable for various applications, such as powering tools or inflating tires. These compressors are commonly used in industries and workshops due to their efficiency and reliability. They can be found in different sizes, from small portable units to large industrial models. The design of a piston compressor allows for continuous operation, making it a popular choice for many tasks requiring compressed air.
