Why use an FRL? | Filter Regulator Lubricator

Many people connect the air hose to their tool and start an application immediately. Is there a better way to help prolong the life of your tool while simultaneously getting better performance from that tool?
The FRL (Filter-Regulator-Lubricator) provides just that.

Most pneumatic tools, regardless of brand, require air tool oil (10 weight – non-detergent) to work at their most optimal level. Manufacturers usually have further requirements (gear-oil or grease depending on the model) for preventive maintenance to prolong the tool life and maintain warranties. The FRL keeps the air tool free from contaminants, helps trap moisture, regulates air pressure (PSI), and helps to prevent operator downtime and manual lubrication of the tool.

FILTER
The filter part of the FRL largely helps to eliminate dust, debris, rust scale, and some water. The water in the line is caused from the condensation that is produced by the temperature change while compressing air. It is important to keep the air motor of the tool free from dust and debris when it is disconnected from the air hose as well. The air inlet and hose ends (plugs and couplers) all need to be clear of dust to work properly.

REGULATOR
The Regulator can be adjusted to provide an adequate PSI at the inlet of the tool based on the manufacturer's recommendations. Using the FRL with larger diameter airlines and less fittings or obstructions is always the better method to supply proper air flow to the tool.

LUBRICATOR
The Lubricator allows oil to be supplied automatically to the air motors. This reduces friction and wear of the moving parts and provides protection for steel components. The lubricator has a setting that allows you to choose how much oil is supplied to your tool based on manufacturer recommendations.

Convenience and ease of mind are the best reasons to use an FRL on all your pneumatic systems. You can continue with your application without the need to stop your work to perform maintenance on your tools. The air system is filtered, regulated, and lubricated helping to ensure the proper conditions needed to operate your tool. There is no guesswork, just consistency delivered every time.
