Compressors: a simple overview?

This data-file aims to give a helpful, basic overview of the world of compressors. The global market is c$40bn per year, growing at a 3% CAGR, which may accelerate in the energy transition. We outline how centrifugal, reciprocating and screw compressors differ.

Next we tabulate costs. A typical industrial compressor might be around 50kW, enough to boost about 2m3 per second of air to the same pressure as a car tire (calculations are given). This might typically cost around $850/kW on an installed basis (data above).

In the energy industry, larger compressors can surpass 10MW-scale. Costs can vary by around 10x depending on the context.

Some of the largest companies are also profiled, but the industry is led by Atlas Copco and Ingersoll Rand.
