Piston compressors are mechanical devices that use a piston to compress air or gas. They operate by drawing in air through an intake valve, compressing it within a cylinder, and then expelling it through a discharge valve. This process creates high-pressure air, which is commonly used in various applications, such as powering tools and inflating tires. These compressors can be found in different sizes and configurations, including single-stage and two-stage models. Single-stage compressors compress air in one stroke, while two-stage compressors compress it in two stages for higher efficiency. They are widely used in industries, workshops, and even for home use.
