FRL

A Filter Regulator Lubricator (FRL) unit is used to prepare compressed air before it reaches pneumatic components. It helps remove contaminants from the air, regulate pressure, and provide lubrication where required.

By helping control the quality and condition of compressed air, an FRL unit can support the reliable operation of components such as directional control valves, regulators, lubricators, and pneumatic cylinders.

How an FRL Unit Works

An FRL unit combines three functions in a single pneumatic air preparation arrangement:

• Filter: Removes solid particles such as dust, dirt, and rust and helps separate water and oil from compressed air.

• Regulator: Controls the air pressure supplied to downstream pneumatic components.

• Lubricator: Adds a controlled amount of lubricant to the compressed-air supply where lubrication is required.

This combination helps provide cleaner and appropriately regulated air to the pneumatic system.

FAQs

What is the purpose of the automatic drain?

The float-type automatic drain helps remove accumulated moisture from the filter section without requiring the drain to be operated manually.

What is the difference between a 2-piece and 3-piece FRL?

The configuration refers to how the filter, regulator, and lubricator functions are arranged within the unit. The suitable configuration depends on the pneumatic system requirements.

How do I select an FRL unit?

Size, connection requirements, required pressure regulation, filtration needs, and whether lubrication is required should be considered when selecting an FRL unit.
