How do I choose an air filter regulator?

An air filter regulator is an essential tool for protecting sensitive downstream equipment. These innovative air preparation devices combine a filter and regulator in one space-saving unit to remove particulates and moisture from the air line and reduce air pressure to a setpoint. Here, Fluid Controls gives you our guide to choosing the right air filter regulator.

What is an air filter regulator?

Air filter regulators, or simply filter regulators, combine a filter and pressure regulator in one unit. Filter regulators are primarily used to maintain a safe supply of compressed air to pneumatic equipment. They do this by removing water and particulates from the air supply, whilst also providing accurate control of downstream pressure. The space-saving single unit design also minimises leaks due to fewer air connections.  

How does a filter regulator work?

A filter regulator combines two primary functions. The filter cleans the air that travels from the compressor by straining and trapping any solid particulates, like dust and dirt, and separating liquids from the compressed air. Meanwhile, the regulator controls the speed and precision of the fluid’s flow. Filters are installed in the air line upstream of regulators, directional control valves, lubricators, and air-driven devices like cylinders.

How to choose a filter regulator

When choosing the right filter regulator for your application, it is worth asking yourself the following questions to aid your selection process:

  • What is the flow rate for the application? Once you have determined the flow rate, you can then select the correct port size.
  • What level of filtration is needed? In other words, how dry does your air supply need to be? General-purpose 40 micron filters typically remove up to 95% of water. The addition of a 5 micron filter will increase water removal further to around 99%.
  • What is the inlet and outlet pressure? It will be the job of the pressure regulator to regulate these parameters. Remember that there will be a noticeable pressure drop through the filter regulator.

You should also consider the following factors when choosing a filter regulator:

  • Ambient temperature
  • Filter drain
  • Materials
  • Pressure gauge
  • Self-relieving
  • Bowl capacity
