How To Choose The Right FRL Unit For Your Compressed Air System

When it comes to compressed air systems, an air filter, regulator, and lubricator (FRL) unit are vital. Selecting a suitable FRL unit for your plan can seem daunting, but it does not have to be. Our blog post will walk through This guide. During the process, you will be guided through all the steps you follow to choose the right product FRL unit for your system, from understanding the types of units available to knowing how to install and maintain it. After reading this post, you will be an expert on air FRL units, and you can choose the perfect one based on your needs.

What factors should you consider when selecting an air filter, regulator, and lubricator (FRL) unit for your compressed air system?


A good air conditioner is essential for a filter, regulator, and lubricator (FRL) unit for your compressed air system; there are a few key factors you'll need to consider. Here's a quick rundown of what you should keep in mind:


1. The size of your compressed air system

2. The type of compressor you're using

3. The specific needs of your application

4. The environment in which your system will be operating

5. Your budget



Here are some details about each of these factors:


1. The size of your compressed air system: The size of your FRL unit should be based on the total volume of air that your system can produce. Choosing the right one is a good rule of thumb, a unit that can handle twice the volume of air that your system can produce. This will ensure that your unit can handle peak demand without any issues.


2. The type of compressor you're using: Compressors can either be oil-lubricated or oil-free. Oil-lubricated compressors require an FRL unit with an oil mist eliminator to remove oil particles from the compressed air before entering the unit. Oil-free compressors, on the other hand, don't require an oil mist eliminator.


3. The specific needs of your application: Your particular application will dictate the exact features you need in an FRL unit. For example, if you're using your compressed air system for painting or sandblasting, you'll need a team with a high flow rate to ensure a smooth finish. On the other hand, if you're using your system for pneumatic tools or equipment, you'll need a unit with a pressure regulator to prevent damage to your tools and equipment.


4. The environment in which your system will be operating: You'll need to consider the specific conditions in which your system will be working when choosing an FRL unit. For example, if you're using your system in a dusty environment, you'll need a team with a dust filter to prevent dust from entering and damaging your compressor. Similarly, if you're using your system in a wet environment, you'll need a unit with a water trap to prevent water from entering and damaging your compressor. 


5. Your budget: Last but not least, you'll need to consider your budget when choosing an FRL unit for your compressed air system.

How do you know if an FRL unit is the right size for your system?


How do you know if an FRL unit is the right size for your system? The answer may surprise you - it's pretty simple. Here's what you need to do:


1. Determine the size of your air compressor. This is usually given in cubic feet per minute (cfm).

2. Determine the maximum pressure your system will need to operate at. This is typically given in pounds per square inch (psi).

3. Using a compressor sizing chart, find the point on the chart that corresponds to your compressor's cfm and psi ratings. This will tell you the minimum size FRL unit you need for your system.


Remember that this is the minimum size unit you need - if you want your system to have some extra capacity for future expansion, you can choose a larger unit. But if you select an FRL unit that's too small, your system will be less efficient and may not work as well as it could.

What is the difference between an "inline" and "piggyback" air FRL unit?


When choosing an air FRL unit for your compressed air system, you must decide between an inline unit and a piggyback unit. Inline units are installed in the major airline before the air compressor. Piggyback units are installed after the air compressor.

Inline units are typically smaller and less expensive than piggyback units. Piggyback units may be a better choice if your system already has an inline unit installed or if you need a larger unit to meet the demands of your system.

Which type of air FRL unit is right for your system - metal or plastic?


Air FRL units come in two main varieties - metal and plastic. Metal units are more durable and can withstand temperatures and pressures than plastic units. However, they are also more expensive. Plastic units are a good choice for most applications, but if your system operates at very high temperatures or pressures, you may need to choose a metal unit.

How do you ensure your air FRL unit is installed correctly and functioning?


After you have selected the correct size and type of air FRL unit for your system, you need to install it properly to ensure optimal performance. 

Installation instructions will vary depending on the make and model of your unit, so be sure to consult the manufacturer's instructions before proceeding. 

In general, installation involves connecting the unit to the significant airline before or after the air compressor and connecting it to a power source. 

To ensure that everything is in order, it is essential connections are secure and leak-free. Once everything is connected correctly, you can turn on your system and check that the unit is functioning properly. 

If you notice any leaks or other problems, consult the manufacturer's instructions on troubleshooting and fixing them. By following these steps, you can be sure that your air FRL unit is installed correctly and will provide years of reliable service.

What maintenance tasks should you perform on your air FRL unit?


It is essential to perform regular maintenance tasks on your air FRL unit to ensure it functions properly. These tasks include checking for leaks, cleaning the unit, and replacing worn or damaged parts.


To check for leaks, you must inspect all the connections and seals on the unit. You must replace the seal or gasket if you notice any cracks or holes. You should also check the pressure relief valve to ensure it is not stuck open or closed.


Getting rid of dirt and debris on the unit is the first step to cleaning it. You can do this by using a soft brush or cloth. Harsh chemicals should be avoided abrasives, as these can damage the unit.


If any parts on your air FRL unit are worn or damaged, you must replace them. This includes the filter, regulator, lubricator, and pressure relief valve. You can purchase replacement parts from the manufacturer or a local hardware store.
