Air lubricators

Compressed air lubricators

A lubricator is a device located downstream of the air compressor. It usually consists of a small reservoir with a supply of lubricating oil and a dosing mechanism that dispenses a specific amount of oil into the air stream. The oil reduces the wear of highly stressed pneumatic drives and prevents the formation of rust and moisture. The Festo range not only includes individual accessories such as lubricators, but also complete service unit combinations. Depending on the area of application, they also offer other components for a service unit such as soft-start valves, filter regulators, filters, on/off valves and branching modules.

What to look for in a compressed air lubricator

It is important to use the correct type of oil for your application, as using the wrong oil can lead to problems such as reduced efficiency or even damage to the pneumatic components. It is also important to maintain and properly fill the lubricator, as a lack of lubrication can lead to premature wear and failure of the components.

Service unit combination, MS series

With the MS service unit combinations from Festo, you can prepare every aspect of your compressed air for different applications. The devices are characterised by a wide range of settings, highly functional components and a wide range of services. This means that they can be used individually for simple standard applications as well as for very application-specific solutions with the highest quality requirements. Thanks to the modular design, it is possible to order predefined combinations, individual components, ready-to-install solutions or freely configurable service unit combinations from stock. Depending on the application, these can be made up of filter control valves, lubricators, sensors, dryers, safety functions, flow sensors, on/off valves, branching modules, compressed air assembly valves and filters. The simple connection system saves time when replacing individual modules, which is quick and easy to do without having to dismantle the entire device. Many of the components in the service unit combinations are also UL and ATEX certified.

Possible components for service unit combinations

The following components are possible in service unit combinations of the MS series:

  • Filter regulatorMS-LFR: This component combines a filter and pressure regulator. The grade of filtration is 5 or 40 μm.
  • Filter regulatorMS-LFR-B: This device also combines a pressure regulator and filter in a polymer housing. Its grade of filtration is also 5 or 40 μm.
  • Activated carbon filterMS-LFX: Suitable for removing superfluous and gaseous oil particles.
  • Water separatorMS-LWS: This maintenance-free component can remove condensation from compressed air.
  • LubricatorMS-LOE: This lubricator adds a finely adjustable amount of oil to the compressed air. The proportion of oil mist relates to the flow rate of the compressed air.
  • On/off valveMS-EE-B: This is an electrically operated on/off valve in a polymer housing. It is used for pressurising and exhausting pneumatic systems.
  • Membrane air dryerMS-LDM1: This component is a wear-free membrane dryer with internal air consumption.
  • Distributor blockMS-FRM-FRZ: This device is an air distributor with 4 connections and half the grid width.

Oil and maintain your pneumatic tools in factory automation with various accessories from Festo. Festo offers the right lubricator and the right technical service unit for every function, every tool, every connection, every pressure regulator and every manufacturer.

Application areas for compressed air lubricators

There are many different applications where a lubricator can be used in a pneumatic system. Here are some examples:

  • Textile industry: Pneumatic scissors and sewing machines can be lubricated to reduce friction and wear on the moving parts.
  • Transport of materials: Pneumatic conveyors and other equipment for transporting materials can be lubricated with a lubricator to reduce wear and improve efficiency.
  • Printing industry: Pneumatic presses and dyeing machines can be lubricated to ensure their long-term efficiency.
  • Processing: Pneumatic processing equipment such as ironing and pressing machines can be lubricated with a lubricator to reduce wear.
  • Packaging industry: Pneumatic packaging equipment, such as packaging and wrapping machines, can be lubricated to reduce wear and improve efficiency. A lubricator can help to keep these devices running smoothly, reducing the risk of contamination (e.g. in the food industry).
