Contaminants are bound to creep in and develop in any compressed air system. Air contamination can come in from or develop in:
Given the abundance of food safety standards and guidelines on maintaining clean air, regularly monitoring (with dew meters for instance) and testing the purity of compressed air is the best way to limit air contamination. That’s because the composition of contaminants in the air varies from moment to moment as does the build-up of contamination within the compressed air systems.
In addition to this, leading safety guidelines concur on the need to remove moisture wherever possible and maintaining a dew point of at least -26° C (to limit microbial growth). They also advise setting up of filtration (with a DOP efficiency of at least 99.999%) at any point where the compressed air is likely to come into contact with the product.
It must be noted that these point-of-use filters must be maintained regularly; elements must be changed at least once or twice a year in the first two stages; the replacement frequency needs to be doubled for filter elements in stage three. Dryers, air lines, and drain taps too must be regularly maintained.
