Air Compressor Filters

Our compressed air filters are engineered to reduce leaks, blockages, and moisture, ensuring efficient, long-lasting compressor performance.

Lower Operating Costs

The right filter significantly reduces energy consumption and maintenance expenses by efficiently removing contaminants from the air stream.

Enhanced Air Purity

Atlas Copco filters meet the most stringent air purity standards, ensuring optimal performance for your air systems and pneumatic equipment.

Extended Equipment Lifespan

Our cutting-edge filtration solutions prolong the service life of air systems and equipment by preventing contamination-related wear and tear.

How do I find the right air compressor filter for my application?

The first step is to find out which type of contaminant(s) you have to protect your system from and determine the air purity class required for your application.

 

Identifying the contaminants in your system and determining the required air purity class for your application. Atlas Copco offers a wide range of compressed air filters specifically designed to tackle various threats. Use the table below to select the optimal compressed air filter based on the contaminants present in your system. This ensures your air filtration system operates efficiently and protects your equipment from harmful substances.

Why choose Atlas Copco’s range of air compressor filters?

Atlas Copco’s dedicated filtration team is always looking for ways to give you competitive edge. Our new generation of compressed air filters features several innovations that make your air compressor system more efficient and its operation easier. Here are just three examples:

The ideal filtration technology

To ensure that your system is optimally protected, our filters use different filtration technologies – each designed to take on a specific threat to your airstream. They include:

Wrapped media for wet particles: Wrapped media are known for their durability in wet and oil-contaminated environments. Our patented Nautilus technology combines multiple wrapped layers to offer constant air quality at the lowest pressure drop, even in the harshest working conditions.

Pleated media for solid particles:Pleating is the optimal technology for capturing dry particulates in compressed air. Pleated media have a large surface area and therefore ensure a longer filter service lifetime and lower pressure drop.

Macro-structured activated carbon: Macro-structured activated carbon has a larger surface compared to the typical carbon filter media, giving it a superior adsorption capacity and a steady performance over a longer time.

Cyclone for water: The use of centrifugal forces secures a proper separation of liquid water droplets in the air flow.

In addition to outstanding filters, you also get the revolutionary built-in bypass that allows you to service your filter without disrupting the air flow.

To you that means big investment savings by eliminating the need to install an expensive external piping bypass, lower operating and energy costs as well as reduced maintenance times.

Service indicator

To ensure constant air quality, a service indicator allows for an easy check of the filter’s running hours differential pressure, and the maintenance status. It can even send a remote alert.

This table provides information about compressed air filters and their general applications.

Which filter for which purity class?

Another way of finding the right filter is to look at your application to determine the air purity it requires according to the international ISO 8573-1:2010 standard. The table below shows the various ISO 8573-1:2010 air purity classes and the Atlas Copco filters and dryer-combinations that meet these classes. To learn more about ISO 8573-1:2010, read our comprehensive blog article on ISO classes for compressed air quality.
