Getting to know Your Compressed Air FRL

Properly treating compressed air before use is critical in any compressed air system, but choosing the right air treatment equipment can be challenging. In order to choose the right air treatment equipment, you must first understand your application, environment, and requirements. When selecting the right air treatment equipment, it is important to know the system pressure, operating temperature, airflow, port sizes, etc. It is also important to determine what type of air you will need. As the facility’s air treatment equipment becomes more sophisticated and requires a more stringent ISO class of air, the quantity and sophistication of the equipment will change. Generally speaking, choose parts that have been thoroughly tested and designed to withstand the toughest operation, vibration, and impact conditions.

Compressed air treatment

Compressed air is treated in the compressor room (right after generation and before drying, and right after drying) and at the point of use in a properly designed compressed air system. Air treatment units at the point of use are commonly known as FRLs, which stand for Filter, Regulator, and Lubricator. The FRL provides point-of-use filtration, management, and treatment of compressed air. This point of use control is essential for maintaining the health of your production equipment in most cases. Here is an overview of the different types of FRL available. 

Airmax offers the following FRLs for using a compressed air system

  • Air filters
  • Air Pressure regulators
  • Air Lubricators

Each system does not need all three FRLs, but every system needs some basic level of filtration to prevent piping and/or machinery failure. You can determine the appropriate mix of filters, regulators, and lubricators by knowing your application and requirements.

Air filters

Air filters remove solid particles as well as bulk liquids. A filter of this type is ideal for removing pipe scale, rust, pipe dope, and other solid particles or debris that may break loose upstream and travel downstream to the installation site. All compress air generated should pass through the dryer being use, but a particulate filter can provide extra protection from water and oil entering the machinery. The air filter can capture particles down to 5 microns in size. The diameter of a human red blood cell is 8 microns. You can use Air filters as standalone elements or as prefilters for coalescing filters when installing filters.

Air Pressure regulators

Within a compressed air system, an air pressure regulator controls the outlet pressure. Pressure is control by dialing in the desire pressure, then an internal control spring raises or lowers the flow of air, which raises or lowers the pressure in the pipe. Energy conservation, personal safety, or process control require the use of regulators in applications where pressure needs to heavily control. It is also possible to transform a volatile supply of air into a controlled, constant supply using an air pressure regulator.

Air Lubricators

Lubrication oil is most finely by an air lubricator for downstream applications. Lubrication oil is most finely by an air lubricator for downstream applications. Air lubricators should only use in compress air systems that require trace amounts of oil. For the oil mist to reach its desire location, these units must install after the filters and close to the point of use.
