Types of Air Compressors
Types of Air Compressors
Air compressors come in a variety of forms and sizes, from handheld airbrushes to large industrial air rigs. The most common type is the stationary or portable electric-powered compressor. Here are the four main types:
1. Piston/Reciprocating Air Compressors
Piston or reciprocating air compressors use a piston in an air cylinder to compress air, creating high-pressure air. They are typically lower cost and provide a wide range of pressure and air flow.
2. Rotary Screw Compressors
Rotary screw compressors use two intermeshing helical screws to compress air. They are more efficient and reliable than reciprocating compressors but also tend to be more expensive. They provide a more consistent and higher pressure than reciprocating compressors, as well as a smoother flow of compressed air.
3. Centrifugal Air Compressors
Centrifugal air compressors use centrifugal force to compress the air, resulting in higher pressure than reciprocating models. They use far less power to achieve the same pressure level, making them more energy efficient.
4. Low-Pressure (L-Pair) Compressors
L-Pair compressors are designed for use with low-pressure applications and industrial settings where noise reduction is a priority. These compressors provide a quieter operation, allow for smaller physical size, and are more affordable than centrifugal compressors.
No matter the type of air compressor you need, it’s important to consider the application and your budget when deciding which type to purchase.
