For example, the company says that when it comes to air pressure, higher isn’t always better. Optimal air installation ensures the best tool performance and durability while ensuring operator safety. Two factors are essential to operate pneumatic tools at rated specifications: A dynamic air pressure of 90 psi (6.3 bars) at the tool's limit, and recommended air flow – given by the tools manufacturer.

The motor of a pneumatic tool transforms compressed air energy into motion (kinetic energy). For typical air powered tools, the recommended dynamic air pressure at the tool inlet is 90 psi. The air pressure is the force exerted by the air per unit of surface. Commonly used pressure measurements are (psi) pounds per square inch and (b) Bar. Static Pressure is the pressure obtained in a closed system, when the tool is not in operation. Dynamic Pressure, on the contrary, is the pressure obtained when the tool is in operation.

To measure the dynamic pressure at the tool inlet, simply use a pressure gauge with T-inlet and run the tool (also known as free speed). In specific cases when a tool comes with an air regulator, such as a pneumatic grinder, use the grinder, and apply the usual feed force before measuring. Air flow is the amount of air that passes through a surface per unit of time (cfm) cubic feet per minute / (l/s) litres per second.

The values listed in many tool manufacturers' catalogues (such as torque, air consumption and maintenance cycles) are measured with standard dynamic air pressure of 90 psi. In many cases, the difference between the catalogues performance values (i.e. torque, rotational speed), and what is delivered when in use, is due to the pressure drops occurring in the section between the pipe-end and the tool.

To ensure high productivity and energy savings, all pressure drops should be kept to a minimum. Factors such as hose diameter can influence pressure drops. Take for example an application with an air flow of 15 l/s and a 20m hose. Increase the hose by 3mm and you can decrease pressure drops by 76%. Generally, it is best to keep the internal diameter of the hose as large as practical to avoid pressure drops.

Always recommended is the use of Filter/Regulator/Lubricators (FRL) as a key accessory as this ensures the right air flow and pressure at the tool inlet. The filter cleans compressed air, trapping solid particles such as dust or rust. The regulator ensures the consistency of the dynamic pressure for better tool performance. The lubricator adds controlled quantities of airline oil to reduce friction between moving parts in the tools air motor. Chicago Pneumatic recognises that in many working environments the same hose is used for multiple tools. Here,the company recommends the use of ‘hose whips’ to reduce hose bending and protect the tool operator from potential hose whip injuries in the event of coupling failure or hose damage.
