Air Compressor Idea!

[4v shane]

As of right now I have a Devilbiss/Delta 6.5 horse 80 gallon compressor. I do a lot of sandblasting on a daily basis as I do powdercoating/Ceramic coating. I was pondering the idea of adding an additional tank to my setup such as a 30-80 gallon reservoir tank. I have a local shop who services compressors and sells parts and has access to rebuilt motors and pumps. My main idea was to add the additional tank for time being until he gets me setup with a larger pump and motor to make a monster compressor.


Has anyone done something like this on here? Pros? Cons? What size upgradded pump/motor should I go for?

you can never have too much air tank

well I suppose you can, you don't want to run over the duty cycle of your compressor before they're full

At the end of the day it won't help you any. When you have a small tank you can blast for 5 minutes and wait 5 minutes for it to recover. If you have a big tank you can blast for 10 minutes and wait for 10 minutes for it to fill (times are for example only). So at the end of the day you can only run the blaster for 1/2 the time available. The amount of blasting you can do in one day is determined by the capabilities of the PUMP/MOTOR and not the tank size.

I would suggest that you consider a second compressor on line with your existing one.

no neat sig line

The other option is a 2nd pump and motor tied to the same tank... 80gal tank is big enough, you just need a pump/motor combo that can put out enough CFM to keep you in supply....

Either get one bigger compressor, or get a second one, plumb them together, and adjust the low pressure setpoint on the second one 5-10# lower than then first. Then, one compressor will be a lead and the other a lag when you have additional demand.

Ask your "compressor shop" to keep an eye out for a good used 2nd rig for you.
