Hi, 

 

We are using a small qty of compressed air - Direct contact and working to achieve classification 1:2:1 for Particulates, Water and Oil. does anyone have any ideas on the benchmark parameters for Micro and what organisms we should be looking to test for? 

 

Thank you

I have found it very hard to find standards for micro counts for the air as well.  Not sure what products you are making but there was an article related to Microbial Quality of the Air in Meat and Dairy Plants that provided a few different standards in the article; pg 10 "The APHA recommendation of aerobic count and yeast and mold count to be less than 100 cfu/m3. In addition to APHA others proposed recommendation are according to Kang and Frank [7] maximum levels of mesophilic aerobic bacteria of air could be 180-360 cfu/m3 and yeast and molds could be 70-430 cfu/m3 for in milk processing plants. According to Krzysztofik [32], the permissible level of aerobic count of air in meat industry should be less than 500 cfu/m3 by settle plate technique."

The article is titled "Analysis of Microbial Quality of the Air in Meat and Dairy Plants by Impaction Technique"  https://bepls.com/be...oct_2018/2.pdf

We follow the above APHA recommendation for our facility and we have been audited many times against it and never had an issue.
