1. Quality of air source
¡Install an air filter on the upstream side of the booster regulator.
Select an air filter with a filtration degree of 5 μm or finer.
¡If dry air (atmospheric pressure dew point: –23°C or less) is
used, the life expectancy may be shortened because dry air
will accelerate evaporation of grease inside.
2. Pressure fluctuation
¡Provide a stable supply of pressure for the inlet pressure.
3. Take measures to ensure air quality, such as by
installing an aftercooler, air dryer, or water separator.
¡Compressed air containing a large amount of drainage can
cause the malfunction. Therefore, take appropriate measures
to ensure air quality, such as by providing an aftercooler, air
dryer, or water separator.
