Calculating Compressor Size

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.   

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.

 Pneumatic System Maintenance
 - Be certain that:

‡

Pneumatic  ttings are tight and do not leak.

   and ensure that automatic draining systems are
   operating correctly.

‡$LUOLQHVDUHFOHDUHGWRSUHYHQWIUHH]LQJ

   especially in winter.

‡/XEULFDWRURSHUDWLRQLVFKHFNHGUHJXODUO\DQG

   ensure it has an adequate supply of lubricant.

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.
