[Shop-talk] Looking to buy a compressor

[DAVID MASSEY]

 Not much you can do other than move.  ;-)
Perhaps some sort of automatic drain will make the task less arduous.  The compressor here at work has a solenoid valve that is actuated for 5 or so seconds every time the compressor cycles off.  Set and forget.

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%

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.

The transmission cooler I’m looking to use is a "stacked plate” design, and has a pressure rating of 200 PSI.  It says it has a 29,200 BTU rating:

I do plan to put a small box fan to blow through it as well.
Here are some pictures, but these all seem to be between the compressor and tank, mine will be mounted on the wall after the tank.

Good point.  I hadn't thought of air flow rate.  Hook several in parallel?

 That's a clever idea.  It is an excellent heat exchanger and is good for the pressure.  But it could restrict air flow.  Most are just a long, serpentine tube with fins.  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.

I’d be concerned with using a transmission cooler for an aIr cooler because they are not designed for pressure use. I wouldn’t think a trans cooler would need to be rated at more than 10psi. 

An air conditioner condenser would probably be better.  It even has "condenser" in the name.... _______________________________________________
