What is FRL Air Treatment?

In pneumatics, air that leaves the compressor is dirty, wet, and over pressurized, which can damage the operation of the downstream equipment, including valves, air tools, and cylinders. Thus, there is a need to apply proper air treatment before and after compression. With that in mind, in pneumatics, compressed air is treated through air preparation units, known as FRL combination.

FRL is a compressed air system combining a filter, regulator, and lubricator units into one block used to generate clean air, improve its quality, control pressure and lubricate flow to provide a proper pneumatic system operation and increase the pneumatic products’ longevity.

#Three Units of FRL

There are three components of FRL – filter, regulator, and lubricator. These units can be bought separately or as one unit as FRL. First of all, you should understand the air requirements of your pneumatic system to make the right purchase of FRL units. Install FR (filter and air pressure regulator) if your pneumatic tools are self-lubricating. If not, you should choose an FRL unit that includes lubrication.

1-Filter – The first step to improve air quality is filtration. Filters remove moisture, dirt, and other contaminants from the pneumatic system. Filters can be attached with semi-automatic, manual or automatic drainage systems to eliminate filtered contaminants.

2-Air Regulator – Air pressure regulators regulate the air pressure of a pneumatic system so that downstream equipment will not exceed its maximum pressure. They provide a constant air pressure, minimizing variations. The air regulators are divided into two types: relieving and non-relieving. Reducing air compressor regulators let excess air escape through a built-in vent whenever there is a pressure surge. In contrast, non-relieving air compressor regulators can’t release the pressure and need a secondary mechanism for doing that.

3-Lubricator – Lubricators release controlled amounts of oil into the compressed airflow. They help to lubricate moving parts of pneumatic tools and equipment, reduce internal friction, protect against wear, and increase their lifespan. There are two lubricator types – oil-fog (for short distances) and micro-fog (for long distances).

#Benefits of FRL Unit

Here are the benefits of the FRL combination:

● Provide higher reliability of pneumatic tools
● Ensure clean and high-quality air
● Provide constant pressure
● Increase the pneumatic component lifespan
● Reduce power consumption
