In compressed air systems, inline air water separators and oil coalescing filters are mechanical devices designed to remove liquids, bulk water and oil, and particulates from the air or gas.
The term "inline" is used to describe these filters because they are installed directly in the air supply line, usually between the air source and the equipment that requires clean air. By placing the filter in-line with the airflow, it can effectively capture and trap the particles, preventing them from entering the system or equipment downstream.
In this article we will discuss where to place air filters in your shop and how to install them.

When it comes to placement in the compressed air system, air filters are recommended to be installed:
This allows the filter package to remove bulk liquids, oils and particulates before entering the air dryer or the equipment itself.
As far as where in the shop to place an inline air filter, see the video below for an overview of how to plumb your shops air system:
There are a few things to remember when installing air water separators and oil coalescing filters. The first is that any type of alteration from the original design may cause failure in operating parameters so it is best to avoid altering the filtration system.
Before any installation or maintenance, it is vital to release the system pressure.
Once that has been accomplished remember to:
The maximum operating pressure is 250 PSI and the maximum operating temperature is 175° F. Any deviation from the maintenance instructions could result in operating failure. Likewise, exceeding flow rates can be detrimental to the operation of your system.
After your air system is properly set up, the filter or filter package can be installed. This process may vary slightly based on the type of pipe in your air system. Each of the steps outlined below can be found with more in depth information in the video below.
Look for a location relatively close to the application and after a drip leg to install a riser pipe. Decompress the system and open up ball valves. For safety reasons, ensure there is no air pressure in the piping and safety glasses are worn during the installation.
Determine the size and placement of your pipe T-fitting and cut the pipe. Slide the fitting into place, adjust to ensure it is in an upright position, and lock into place. Place the pre-plumbed riser pipe system in the T-fitting and lightly secure. Do not lock into place at this step. Install a ball valve at the bottom of the pipe for easy pressurization and filter maintenance.
Slide the filter package onto the pipe. Mark off and drill holes for mounting onto the wall. Screw or bolt the filter package to the wall. Install the gauge for the regulator.
Ensure all fitting and connections are snugly tightened to ensure a solid seal. Pressurize your system.
While the installation process may be easily understood, some questions may arise once you get into the process. For more detailed information, these installation manuals are available:
