QUESTION

How often would you suggest I take an oil mist sample at the ACG’s sample support port?


ANSWER

The frequency of routine sample testing depends upon the level of usage of the compressor, how close to the design limits it is used and the scale of impact that contaminated gas would have on the compressed air system to which it is attached. As a minimum we would recommend performing an oil mist sample test at least once every three months, to coincide with the calibration checks of the other sensors in the ACG.

 

Another good practice is to perform an oil mist sample test when the water, CO or VOC sensors alarm as they may be indicating a compressor problem, particularly if the source of the alarming contaminant is not obvious.
