We’ll discuss four types of filtration that help maintain an air compressor’s longevity. Let’s dive into it and learn what they are.

Pre-Filteration:

Pre-filtration is one of the essential filtration processes for any air compressor system. It consists of the following points:

  • Pre-filtration helps prevent larger debris, dirt, dust, and water droplets from entering the system.
  • It acts as the first line of defense to filter out the large particles before further filtration stages.
  • It also helps to extend the life of filter elements, since it removes the large particles before they reach the main filters.

Coalescing Filtration:

Coalescing filtration is used for removing tiny oil droplets, mists, and aerosols that are too small for a standard particulate air filter to capture. Take a look at the essentials:

  • It is an important filtration stage, especially in compressed air applications that require clean and moisture-free compressed air.
  • It removes the particles in the sub-micron level (0.01 and smaller) from the compressed air.
  • Coalescing filtration plays an important role in keeping the air compressor’s essential components, like the compressor itself, pneumatic tools, and valves clean.

Particulate Filtration:

After coalescing filtration, remaining solid particles, such as dust and other contaminants, are removed via particulate filtration. Here are a few points to consider:

  • Sub-micron particles which have not been removed by pre-filteration and coalescing filtration, are removed by particulate filtration.
  • It helps in reducing the wear and tear on the air compressor, extending its life.
  • It can also prevent issues like air leaks, which could lead to lost pressure.

Adsorption Filtration:

The final stage of air filtration is adsorption. Let’s see the significance of adsorption:

  • This stage removes oil, vapor, and remaining odors.
  • Adsorption filtration uses activated carbon to eliminate any remaining impurities, producing clean air.
  • It helps maintain the air compressor’s performance parameters required for various applications.

Knowing the types of filtration needed for an air compressor is essential to maintain its longevity, improve the quality of the compressed air, and to ensure the safety of those using it. So, invest in the right air compressor filtration that suits your needs, maintain them properly and remember to replace them regularly to enjoy the cleanest, highest quality compressed air possible.
