[Shop-talk] Looking to buy a compressor

[Pat Horne]

I’m in central Texas with a 60 gallon compressor with a small point of use water precipitator at my blast cabinet. EVen draining the tank daily the precipitator About every 10 minutes. There is also a Dick sander running on the same compressor. The compressor cycles so I’m using about 10 CFM. Much more water than I’d like. 

Currently 93° & 45%

Peace,
Pat

Howdy,

Are you painting or in a super high humidity environment or something?  My experience with compressors is that mostly I can remember to drain the tank every now and then and it all "just works" without any elaborate coolers / separators / whatever.

YMMV.

It all depends on what air tools you are using.  It is possible that you couldn't run a sand blast cabinet through it.  But you could hook up the high volume users to bypass the cooler and save the dry air for the tools that need it.
