Pneumatic Lubricators Information

Pneumatic lubricators are used in compressed air lines to atomize oil into aerosol form for injection into an air stream. The air stream is used to lubricate pneumatic tools, cylinders, motors, and valves. Pneumatic lubrication equipment includes devices such as line oilers as well as complete pneumatic lubrication systems. In a stamping lubrication system, the pneumatic lubricator is inserted in the machine itself. To protect downstream equipment, the lubricant is dispersed as an oil mist in discrete amounts. A complete pneumatic lubrication system also uses a metered quantity of air to remove moisture, rust, atomized particles, and dirt from machine parts. Pneumatic concentrators, pneumatic conveyors and pneumatic cartridge loaders are examples of machines that use pneumatic lubricators.

Specifications and Features

Pneumatic lubricators differ in terms of specifications and features. A regulator lubricator can operate over a range of pressures that are measured in pounds per square inch (psi). The ambient operating temperature for a pneumatic lubrication system is also a range. Modular pneumatic lubricators are designed to be incorporated into existing pneumatic systems. They differ in terms of working pressure, operating temperature, and bowl capacity. Features for pneumatic lubricators include automatic shut-down, warning lights, and dirt stoppers.


Pneumatic lubricators are used in a variety of medical, packaging, and printing applications. They are also used in automotive, aerospace, electronics, and textile manufacturing. Filter lubricators are used for edge and depth filtering purposes. Modular lubricators are designed to improve machine performance and increase the life of machine tools. Constant feed lubricators can work with heavy oils and are designed to provide continuous lubrication for mining and construction tools under heavy stress. Some pneumatic lubricators are manufactured by suppliers that adhere to International Standards Organization (ISO) guidelines such as ISO 9000. In Europe, products bear the CE Mark to indicate compliance with relevant European Union (EU) directives for health and safety.
