AIR CONSUMPTION GUIDE When assessing the size of a compressor to operate air and equipment please use the air compressor FAD (free air delivered) - this is the correct volume you need to know in order to ensure that a compressor wilf operate your equipment efficently. Column 1 is manufacturers stated tool consumption under continuous use in CFM. Column 2 is average time of use in seconds. Column 3 gives CFM required to operate tool under normal conditions of use.
