Air Compressor detail drawing.

This Architectural Drawing is AutoCAD 2d drawing of Air Compressor detail drawing. Coming to Terms. When it comes to compressors, there are three main specifications that determine performance: cubic feet per minute (cfm), pounds per square inch (psi) and horsepower. The cfm measures the volume of air that a compressor delivers. The psi indicates the amount of pressure behind the air. Air compressors work by forcing air into a container and pressurizing it. Then, the air is forced through an opening in the tank, where pressure builds up. Think of it like an open balloon: the compressed air can be used as energy as it's released.
