Air Filters

Modular Inline Air Filters for Pneumatic Systems & Industrial Automation

The Pneuforce XOF Series inline air filters are designed to remove water, dirt, rust particles and contaminants from compressed air systems, helping protect pneumatic valves, cylinders, sensors and regulators from premature wear. Featuring a compact modular design, these filters are ideal for machine builders, OEM equipment manufacturers and industrial maintenance professionals seeking reliable compressed air preparation equipment.

Built around a proven modular platform commonly found throughout industrial automation, the XOF Series can be used as a standalone compressed air filter or assembled with pressure regulators and lubricators to create a complete FRL (Filter-Regulator-Lubricator) assembly. Their compact footprint and flexible installation options make them suitable for packaging machinery, robotics, automation systems, machine tools and general manufacturing equipment.

Why Use an Inline Air Filter?

Compressed air frequently contains water, compressor oil, rust particles and pipe scale that can damage sensitive pneumatic equipment. Installing a quality inline air filter removes contaminants before they reach valves, cylinders and instrumentation, helping improve reliability and reduce maintenance costs.

Proper compressed air filtration is one of the most effective ways to extend the life of pneumatic systems while improving overall machine performance.

Modular FRL System Assembly

The XOF Series can be assembled directly with pressure regulators and airline lubricators using FRL assembly kits. This modular approach simplifies installation, reduces piping requirements and provides a clean professional appearance for machine builders and industrial users.

Modular compressed air preparation systems are widely used throughout manufacturing because they make maintenance easier while allowing future system expansion.

  • OEM machinery
  • General factory compressed air systems

Frequently Asked Questions

What does an inline air filter do?

Inline air filters remove dirt, water droplets, rust particles and contaminants from compressed air systems to help protect downstream pneumatic equipment.

Why is compressed air filtration important?

Contaminated compressed air can damage pneumatic valves, regulators and cylinders. Proper filtration improves reliability, reduces maintenance costs and extends equipment life.

What micron filter element should I use?

The standard 40 micron element is suitable for most industrial pneumatic systems. Optional 5 micron elements provide finer filtration where cleaner compressed air is required.

Can these filters be assembled into an FRL unit?

Yes. The XOF Series is designed to be assembled with pressure regulators and lubricators using FRL assembly kits.

What does FRL stand for?

FRL stands for Filter, Regulator and Lubricator. These three components are commonly combined to provide complete compressed air preparation.

How often should an air filter element be replaced?

Replacement intervals depend on air quality and operating conditions. Filter elements should be inspected regularly and replaced when contamination or excessive pressure drop is observed.

Can these air filters be used on their own?

Yes. The XOF Series can be installed as a standalone airline filter or combined with other FRL components.

What industries use modular air preparation systems?

Modular FRL systems are widely used in manufacturing, packaging, robotics, machine tools, automation equipment and general industrial compressed air systems.

How do I choose the correct air filter size?

Select the filter based on airflow requirements, port size, operating pressure and acceptable pressure drop within the system.

What are the benefits of a modular FRL system?

Modular systems simplify installation, reduce piping, improve maintenance access and provide a clean professional compressed air preparation solution.
