Question: What protocol do you recommend for monitoring contaminants in compressed air?
Answer: Any recommendation is dependent upon the intended use of the air. In applications where compressed air does not come in direct contact with the food being prepared, less expensive compressors with oil are used. In this case, filtration of the final air being supplied is typically done at the point of use (a box maker, case packer, wrapping machine, etc.). It is also common to have a moisture trap at the point of use to minimize the amount of oil or moisture that could affect equipment components.
