The proportional oil atomizer adds a precise adjustable amount of oil to the compressed air flow. The pressure drop that occurs when air flows through a Venturi nozzle is used to transport oil from the container to the dropper cap. From here the oil drips directly behind the air duct into the proportional valve, where it is atomized. The oil mist component is proportional to the compressed air flow rate.
