Technical Specifications – Lubricator MS4-LOE
The proportional lubricator adds a precisely adjustable amount of oil to the compressed air.
The pressure drop that occurs when air flows through a Venturi nozzle is used to feed oil
from a reservoir to the drip cap. From there, the oil drips into the air duct directly
behind the proportional valve, where it is atomised. The amount of oil mist is proportional
to the compressed air flow rate.
