AIR SYSTEMS
Calculating Compressor Size
Use the air consumption chart in the Tool
Schematic for each tool when calculating
the operating requirements for the tools.
Paslode tools are designed to operate ®
efficently between 90 and 120 psi and should
never be operated at pressure greater than
120 psi.
The air consumption chart will help you find
the correct compressor size for your appli-
cation that will quickly replenish tool air pres-
sure. To use the chart you will need to know
how many tools will be used and approxi-
mately how many fasteners will be driven
each minute by each tool on the line.
Using the equation:
Number of tools X average fasteners/minute/
tool X 1.2 (safety factor) X air consumption
(scfm) @ pressure* (psi) = scfm required.
We can use the following example:
10 tools X 30 fasteners/minute/tool X 1.2 X
0.051scfm* (@100psi) = 18.36 scfm.
*This number is found in the air consumption
chart.
In this example, using the air consumption
chart we find that a compressor providing
at least 19 scfm of air is required. Because
in compressors approximately 1 hp is required
to produce 4 scfm, a compressor of at least
5 hp is required.

Calculated Required Piping
For example, given a 20 hp electric compressor
supplying approximately 80 cfm of air at 120 psi
and a main supply pipe length of 350 feet, we see
by the table the minimum main pipe inside diam-
eter required for this application is 1-1/4 inch.
