- 16kW to produce 100CFM at 100PSI - [1]
- 0.4 kW takes 20 CFM - [2]
- The above 2 numbers point to 3kW for 20 CFM - to get 0.4 kW out - or 13% efficiency of air tools. Extremely low.
More:
- 0.3kW for 7 atm CFM - [3]
- Thus yes, if a tool needs 20 CFM at 7 atm - or 7 kW for its output. that is less than 10% efficient.
