Make sure the compressor model you use has
sufficient cubic feet per minute (CFM) output for
the air tool you plan to connect. Most air tools will
have an air requirement stated in terms of a spe-
cific CFM at a specific pressure (PSI). Most com-
mon is a rating at 90 PSI. Consult the chart below
to determine the output of your compressor
model.

The compressor should put out a higher CFM
than the tool requires. If connecting multiple tools
which will be used simultaneously, then the CFM
for each tool should be added together and com-
pared to the compressor output value.
Consideration should also be given to the type of
usage. A nailer or staple gun uses air in short
bursts and it is easier for the compressor to main-
tain pressure. A paint sprayer or grinder tends to
use a more continuous stream of air as these
tools are run for longer time periods. It is always
better to oversize a compressor to allow for vari-
ation in the type of usage and the number of tools
to be powered. Air tools being operated with
insufficient air volume will not perform their func-
tion satisfactorily.
Connect the tool using a good quality air line with
an adequate length to reach from the compressor
to the point of use. Quick-connect couplers are a
good option for fast and sure connection of tools
and air hoses. Make certain the air hose will not
be placed in a position where it can become con-
stricted or cut by a sharp object. Having a hose
run over by heavy vehicles may not cause an
immediate leak, but it will shorten the life of the
hose.
