Air compressor size formula
Amount of air required
=number of Staplers
×average staples driven each minute per
Stapler
×air consumption at given air pressure×safety factor (always 1.2)
Example: 3 Staplers (N3804AB3) operating at 100
psi driving 30 staples per minute
Amount of air required
=3 
× 30 × .025 (.73) × 1.2
=2.7 CFM (ft3/min) (78.8 ltr/min)
After making the calculations as shown above, you
should find a compressor providing 2.7 CFM of air
that is required.
