AIR TOOL TECHNICAL INFORMATION

AIR PRESSURE INFORMATION

Pressure is the pushing force or power which drives the tool. Correct air pressure is very important, too low and the tool will not perform at its maximum, too high, wear and damage to the tool will dramatically increase and at worst can lead to a potentially deadly failure or accident!

Air pressure is commonly measured in:
- PSI (Pounds per Square Inch) - BAR
1 BAR = 14.5 PSI

Equipment Consumption is the amount of compressed air the tool will use (at the manufacture specified pressure)

Air consumption is commonly measured in:
- CFM (Cubic Feet per minute) - LPM (Litres per minute) - LPS (Litres per second)
1 CFM = 28.32 LPM or 0.47 LPS

AIR PRESSURE NOTES

FAD (Free air Delivery)
When selecting compressor size the output should always be measured as the FAD rating of the compressor. This is the actual volume of air (in CFM, LPM, LPS) discharged by the compressor therefore a more accurate measure of the air available to use.

Displacement
Is the theoretical volume of a compressor also measured in CFM, it should not be used as a basis for selecting a compressors ability to run a tool.

Pressure vs consumption
Ensure your compressor can output the required air at the specified pressure. Pressure and consumption are not the same thing!

Tank size
Many people mistakenly look at the tank capacity (in litres) of a compressor as the main criteria for running a piece of equipment. Tank capacity is purely for storage and to reduce the running of the compressor motor. The compressors FAD measured in CFM is the critical criteria to determine whether it will run a specified piece of equipment.
