There are a number of reasons why some technicians and maintenance managers opt for air tools over cordless tools.
Fitting a moisture trap/filter and automatic oiler to your compressor is the best way to ensure long life from the tool.
Replacing standard quick change couplers and studs with “high flow” quick change couplers and studs will increase the tools performance, but this step is not recommended for rotary abrasive tools.
An air tool is powered by either a rotary vane air motor (most tools), or a reciprocating air powered piston/cylinder (air hammers and saws). Air tool manufacturers all design their air tools to operate at 90 psi constant air pressure.
