Air quality standard

Does your air supply need to meet the international standard for compressed air quality? ISO 8573:2001 is the internationally recognised standard; by using our air purity check service you can establish your conformity to this standard.

Where the compressed air system is supplying air to more than one application, the air treatment in the compressor house is likely to remain unchanged. However, point of use protection levels will vary depending upon the air quality requirements of each application.

To ensure your compressed air meets current standards and requirements contact for a free no obligation review.
