Ben, I have to disagree strongly with your advice here. Compressed air, whether clean or not, should never be directed into precision machinery. It will blow particles in the machinery into recesses between the parts, where the mating surfaces will be scored or offset from each other and the machinery's precision will be compromised. A single object with no mating surfaces (like film, or a single part from a machine) can be cleaned with clean low-pressure air, but an assembled machine made of multiple precision parts should never be cleaned this way. Ask any master machinist if you don't believe me. - -Patrick
