The productivity of any repairing shop is determined by the efficiency of the pneumatic system formed by the compressor, the hoses, and the air tools because they allow getting done a wide variety of works quickly and with security. The core of this system is the air compressor; which provides power to the pneumatic tools.
Selecting the best air compressor for automotive air tools is not space science, it depends on several factors but the main thing you need to be clear is the airflow requirements of your air tools, since the total air flow required depends on them and by the way, the size of the air compressor.
Following you can see a list of the type of air tools shouldn’t be missing in your shop:
– For drilling or cutting, we have drills, grinders, chisel hammers and saws. These tools consume 3 to 8 CFM at 90 PSI.
– For hitting, bending or chiseling there is the pneumatic hammer; which can consume from 3 to 11 CFM at 90 PSI.
– For tightening there are air ratchets, impact wrenches and screwdrivers. These require 2 to 10 CFM at 90 PSI.
– For finishing works are pneumatic sanders, polishers and paint sprays that need a supply of 8 to 12.5 CFM at 90 PSI.
– For clamping, there are nail guns and staplers and riveters. These tools may require 0.3 to 2 CFM at 90 PSI.
– Finally, for jobs where air pressure is required, blow guns, tire inflators and sandblast guns are used. These can consume about 3 CFM at 90 PSI.
What size air compressor do I need to run air tools?
The sum of the CFM of your pneumatic tools will serve as a reference to find the compressor that best suits your needs. At this value of CFM, you must add a clearance of at least 30% to compensate for pressure drops that may exist in the lines and to foresee the addition of any tool in the future.
You should also think if your compressor needs a tank. If some of your air tools work by cycles and you always will carry out your work in the same place, it’s better to get one with a tank. A tank with sufficient capacity will make stops and starts of the compressor motor less frequent and this will allow a longer lifespan.
