Equipment is powered by air compressors using pressurized air that is stored in a cylinder. In essence, the pressurized air represents potential energy that was produced by electric, diesel.
Each tool is also quieter, lighter, more compact, and has fewer parts, which reduces the likelihood of a breakdown.
The compressed air system can be used almost everywhere because a portable air compressor is often driven by a diesel engine. PIF examines industrial portable air compressors in the section below, noting their use and location.
