2. Rotary screw compressors: These compressors use two intermeshing screws to compress the gas. They are more efficient than reciprocating compressors and can operate at higher pressures. They are typically used for medium- to high-pressure applications.
3. Centrifugal compressors: These compressors use a high-speed impeller to compress the gas. They are the most efficient type of compressor, but are also the most expensive. They are typically used for high-pressure applications.
4. Axial compressors: These compressors use a series of rotating blades to compress the gas. They are similar to centrifugal compressors, but can achieve higher pressures. They are typically used for very high-pressure applications.
5. Scroll compressors: These compressors use two intermeshing scrolls to compress the gas. They are relatively new, but are becoming more popular due to their high efficiency and quiet operation. They are typically used for low- to medium-pressure applications.
