Like all of the other machinery in your factory, warehouse, or farm, your air motors need to be properly maintained. The process of caring for your air motors is much less complicated than it seems, as long as you’re aware of the specifications and standards required.
We’ll break them down for you here.
Lubricating Your Air Motor
In order for your air motor to perform optimally, it needs to be lubricated. Make sure to use single-point lubricators that are of the injection type. The others – oil mist or drip types – won’t do the job properly. Ideally, you should set your injection type lubricator so that every fifth cycle, it provides one drop of oil. No more and no less, otherwise, you might over or under lubricate your air motor.
On top of this, you need to use a good quality oil. We highly suggest using Peeroyl R-42 Air Line Oil, however, any type that is specifically designed for pneumatic tools will work. Don’t use any other types of oil, as they can damage the air motor. For example, you need to avoid the ones that contain things like anti-gumming or cleaning agents. These two can negatively affect the rubber components, such as the O-rings, in the motor. Once the rubber components have been damaged, the air motor will malfunction.
Your air motor should have air that’s supplied through what’s known as an FRL. This stands for Filter/Regulator/Lubricator. We recommend that you use an NPT FRL that’s ¾ of an inch. Anything else will not give the nutrunnerthe necessary pressure drop that it needs in order to reach the rated amount of torque.
Air Pressure Requirements
On top of proper lubrication, you also need to use clean air at the proper PSI (pound-force per square inch, for the record) when running your air motor. This air should be regulated at either 85 or 90 PSI. (This translates to 5.8 to 6.1 bar.) Don’t allow the air pressure to get past 105 PSI or 7.1 bar. Running the motor with too much pressure can damage it.
