Hi Hongjun:
You can buy oil free compressors. One company that you could check for
that is Kaeser (www.kaeser.com).
No matter which type of compressor you decide to buy (oil, oil free or
rotary screw), I recommend to install it with an air aftercooler-dryer
unit, a separator, an oil remover, particle filters, etc. Close to the
NMRs you can install a Balston type dryer. The minimum requirements of
the compressor will depend on the quantity of NMRs in your Lab.
If the plans are to continue using the same compressor check if it has
some of the items showed above. If the answer is yes, replace all of
them because it takes less time and add the items not present. With
respect to the oil used for the compressor change it to synthetic oil
(generate less oil vapors).
Regards,
Jose
