What is the minimum size air compressor needed to run a die grinder
According to Powermate, tank sizes are measured in gallons. In general if you will be using air tools that require continuous air, such as a die grinder, then you should consider a larger tank. If your air tool requires short, intermittent bursts of air (nailer/stapler) then a smaller tank size can be used.
Die Grinder requires 8 CFM @ 90 PSI.
Compressors will have a deliverable CFM at a specific PSI rating. These ratings are based on the engine/motor horsepower, pump capacity and tank size.
Air compressors work primarily from air stored in the storage tank. As a result, the amount/volume of compressed air a compressor will hold impacts how well certain tools will work.
Additionally once the tank is filled, a larger tank compressor will not have to run as much to maintain the CFM's provided the compressor pump can produce more CFM's than you are using.
