The Clean Air Solution You Need

Does your commercial or industrial application require your compressed air to meet the highest air purity standards?

Both oil-free and oil-flooded compressors can be designed with downstream mechanical filtration in order to remove all impurities in the air. However, oil-free compressors don’t introduce oil or other lubricants into the air compression process, providing an additional safeguard for highly sensitive applications.

What is Oil-Free Air?

Compressed air purity is defined by ISO 8573.1 purity classes, with oil-free applications requiring Air Quality Classes 1 or 0.

  • ISO Class 0 is based on the specifications of the particular application, below the ISO Class 1 maximum total oil concentration, which can be achieved with both oil-free and oil-flooded compressors.
  • The ISO 8573.1: 2010 table outlines the standards for each of the compressed air purity classes. The table contains the maximum contaminant levels for each of the compressed air quality classes along with the test methods and analytical techniques for each type of contaminant.

Oil-Flooded vs. Oil-Free Compressors

Depending on your application, an oil-flooded compressor may be better suited for your needs. Below are a few factors to consider when making the choice between oil-free or oil-lubricated compressors. Contact our experts to learn more about which compressor solution is right for you.

Oil-Free Compressor Benefits

Prevent Oil Contamination

Oil-free compressors help eliminate potential contamination and improve air quality as no oil or lubricant is used in the compression process.

Reduced Noise Levels

Oil-free designs often produce less noise compared to oil-lubed compressors, resulting in quieter operations.

Environmental Compliance

With their reduced energy usage, oil-free air technology can help you reduce your environmental impact and improve your regulatory compliance.

Oil-Flooded Compressor Benefits

Lower Costs

Oil-lubed compressors have a lower initial purchase price and are generally a more cost-efficient solution.

Suitable for Heavy-Duty Applications

Oil-flooded compressors are highly robust and suited for heavy daily usage or industrial applications.

Greater Air Capacity

When greater airflow is needed, oil-flooded compressors can provide significantly more cubic metres per minute of airflow.

Oil-Free Air Applications

Oil-free compressors are specifically suited to sensitive applications where exceptionally clean air is required and the potential for oil contamination poses significant risks such as financial losses.

At Chamco, our selection of oil-free compressors offers many great options for the following sensitive applications:

  • Automotives

  • Chemicals
