Some time ago, my wife bought me a Harbor Freight Media Blaster. I told her my little 8 gallon compressor wouldn't last 1 minute with the blaster, so we have been keeping an eye out for a new compressor.

 

She has a Home Depot store credit card and it was offering some promotionals, so we took advantage of it.

 

Now, my blaster says it needs 10 CFM@ 90 PSI to operate, so here were my options:

 

#1  60 gallon, 155 PSI, and 11.5 CFM @ 90 PSI  $489.00

OR

 

#2  80 gallon, 155 PSI and 14 CFM @ 90 PSI $849.

So what would you do???

If you can afford, go for the largest one you can.  The numbers those blaster manufacturers put out are way off.  You need all the air you can get and then some.

I don't see any duty rating on the largest one even, so see if it is rated continuous duty.  VERY important when blasting as you usually keep it humming for long times.

I would go for the larger one. It is just short of whay you would need to run a DA sander for a long time but will do well for the media blaster. Good luck.

Get the bigger one,  the smaller unit would not keep up and its annoying having to constantly stop sandblasting waiting for a compressor to catch up. ...I have a RK 5hp compressor 18CFM @90 and it gets time to rest when when I'm using my HF pot blaster.
