Air Compressor Capability

[04sp500]

I have a 6 HP, 150 max PSI, with a 30 gal. tank, compressor that delivers 6.4 cfm at 90 PSI and 8.6 cfm at 40 PSI. Can I use this compressor with a blasting cabinet that requires more cfm at 90 PSI. I have been told that it will work, that I will just have to stop after a while to let it catch up. Stopping doesn't bother me as long as I am getting the same "quality blast". Any help would be appreciated.

yes

Your compressor will work fine it will just need to recover every so often.You can plumb it to another tank to gain more volume but it will also take longer to recover.Use a good quality regulator and adjust your pressure switch to come on a bit sooner if needed.

I wish i thought of useing another tank for mine. i got the same compresor 04sp500 has got. i burned up 2 pressure switch's and they are not cheap.

I have that same compressor, It really sucks having to stop and wait for it to catch up.. Get a bigger one!!

Re: Air Compressor Capability

you can also see if you can get a smaller diameter orifice for you blast gun, that will cut down the cfm that you need to use and you should blast a 60psi because much higher your blast media breaks down at a faster rate.

i don't think blast quality will vary much if you size the orifice so that it's only putting out as much air as your compressor. for example, if you can do 2 square inches a second with 20cfm, maybe you could only do 1si/s with 10cfm. the first you'd have to keep stopping for the tank to recharge, the second you wouldn't. little difference in blasting time or quality.

Quality doesnt change, The amount of time it takes you is what changes!!! Something small can still take a long time if the material is really crappy!! I want to get a bigger one because of this. I can blast for a good 10-15 then I have to wait about 10min for the tank to recharge, IT SUCKS!!! If you got the cash sell your's on craigslist and buy big one...

I just thought you guys would catch on eventually, but I had to step in when it kept on going...... Giving advice to a poster from 6 years ago is pretty much a sign no one noticed.....
