A metering valve on the lubricator regulates the amount of oil in the compressed air:
■
minimum oil to lubricate the tools and prevent corrosion,
■ more oil for cleaning and to prevent wear in the tools.
The oil flow can be stopped by a shut-off valve.
The oil flow adjusts automatically to changes in air demand (one or more tools/consumers on line).
