hi all,
we have an electrical motor operated portable compressor in our lab (Bristol 2.4-40) inorder to produce compressed air for a pneumatic gun. it runs well and doesn't seem to have any mechanical problem. however we have not inserted the purifier catridge(carbon molecular sieve) in the purifier due to non-availability. is it mandatory that the purifier should be used in the model? regards,

It's highly recommended. If, however, you have a very long line from the compressor to the gun - I doubt that any major dirt will end up inside the gun. Does this gun require pneumatic oil? If not, you can screw a small inline filter right on the intake of the gun. If it does require oiling, install the same inline filter at on end of the hose.

Dear Markiz, thanx for your post. the purifier catridge that was missing in the compressor was intended to prevent particles of size greater than 10 microns. as you said, we do have a considerably long line between the compressor and the gun. but how does this eliminate the possible use of a purifier? Our gun doesn't use pneumatic oil. Would the use of the small inline filter be advisable? regards, vijeesh vijayan

I don't know the particulars of your air system or how often you use the gun, but if there is no filter or drip trap anywhere on the line you probably have moisure in the air in addition to dirt. Better safe than sorry. Small inline filter (10 micron is sufficient) srews right into the inlet of the gun. It costs peanuts and will keep water and dirt out of the gun. Good luck.
