Lubricator (Part Numbers)

Lubricator

Features

The proportional lubricator adds a precision adjustable quantity of oil to the compressed air stream.
The pressure drop that occurs when air flows through a Venturi nozzle is used to convey oil from the container to the drip cap.
From here, the oil drips into the air duct directly behind the proportional valve, where it is atomised. The oil mist component is proportional to the compressed air flow rate.

- Proportional lubricator with precision oil metering
- Reduces wear on drive units subject to high loading
- High flow rate
- Quick and easy oil top-up
- Robust metal housing
- Transparent lubricator bowl with metallic bowl guard

The following oils are recommended for Festo components:
