The Air Filter Regulator’s role is to maintain constant air pressure, whatever the fluctuations in the compressed air system. This prevents any variation in pressure that could lead to a variation in the speed of pneumatic tools and equipment. Regulators are also used to adjust the pressure or flow to the specific needs of the application. Some applications require pressure that is lower than the pressure of the main air system. A rule of thumb is that air tools usually need 90 PSI to operate.
Set the regulator based on needs and on the manufacturer’s recommendations. This will prevent overconsumption of air and yield power savings. In addition, it will reduce premature wear of tools and equipment due to overly high air pressure. Always check the regulator’s pressure gauge. Note that the pressure must be adjusted while the system is operating so the air supply reflects that actually needed.
