Regulators and Lubricators – What You Should Know

In the previous blog entry we discussed the first part of the FRL system – the filter — that immediately precedes the end use of the air compressor system. In this entry we’ll discuss the other two components: the regulator, and the lubricator. Both play an important part in making sure your air tools and other machinery are working at peak efficiency.


The regulator, as its name implies regulates the pressure from the compression system pipes to the point-of-use. Basically, it’s a valve that normally stays open unless excessive pressure forces it closed. The regulator prevents too much pressure from reaching and potentially damaging the air tool or other end use device. While the valve can be adjusted manually in most cases there are remote options available and special sensitive regulators can be obtained as well. It may also be a good idea to install an additional pressure relief valve to ensure any faults in the regulator don’t cause damage.


A lubricator is designed to extend the life of your air tools by adding a lubricant to the airflow that can prevent wear and tear. Make sure any liquid used is compatible with the end processes you might require as well as any materials the air flow might come into contact with. In most cases lubricators come as either a drip-type or wick-type the virtues of which will be dependent on your specific use case. In certain fringe cases other liquids have been injected into the system, such as anti-freeze, but substitution of the lubricant is generally not advisable unless otherwise stated by the manufacturer.

Regulators and lubricators are very important to keeping your air tools safe and running well. If you’d like someone to come and take a look at your FRL system or perhaps install a new one, contact the experts at CED today.
