ARO®-Flo mist-type lubricators help ensure that pneumatic devices receive the required lubrication to maintain peak performance, reduce wear and prolong service life. They are designed to provide the correct amount of oil for most general applications in a pneumatic system, delivering a constant ratio of oil to airflow. Precise oil feed adjustment sets the proper oil drip rate. Lubricators should be installed close to the downstream application to ensure effective distribution of oil.
