Purpose and how to use? Relationship to other products?

Use Aer Sampling's modified lubricated vacuum pumps to get the recommended sampling rate of 0.75±0.25 scfm and to avoid floating the valves in dry gas meters (a problem with diaphragm pumps).

The recommended sampling rate has been carefully selected by experts so that it is optimized on the following factors:
Maximizing the catch (on filters)
Minimizing the weight of the sampling train/setup
Sufficient heat transfer to condense 50% water
Able to operate at a pressure drop of around 15 inHg (if filters get dirty)
