The difference between piston air compressor and screw air compressor

Piston air compressors and screw air compressors are two of the most common types of air compressors used in industrial applications. Both types of compressors are used to compress air and provide compressed air to power various tools, but they work in different ways and have different advantages and disadvantages.

Piston air compressors use a piston to compress air. They have a cylinder that the piston moves back and forth in, compressing the air and then releasing it through a valve. Piston air compressors are typically used in smaller applications, such as powering air tools, and are relatively inexpensive. However, they are not as efficient as screw compressors, as they have more mechanical moving parts and require more maintenance.

Screw air compressors use two intermeshing rotors to compress the air. As the rotors turn, the air is compressed and released through a valve. This type of compressor is much more efficient than the piston air compressor, and is typically used in larger applications, such as powering industrial machines and large air tools. They require less maintenance and are much quieter than piston air compressors, but they are also more expensive.
