Guys, I have an Ingersoll Rand 200 liter compressor and the tag says it's a 9Bar unit.
My friend Ashley and I got a soda blasting setup and I think he said we need 200CFM
to run the machine effectively.

From the info I provided could anyone tell me if my compressor is adequate?.
I don't have a clue.
Thanks all.

Mike;

9 bar is just the pressure- you'll have to look on the compressor data plate or in the manual to find out what the volume (CFM) is. Over here the CFM is usually specified at 90 psi.

Yep, it's all about how fast the pump can replenish.

Mikey,
If a system says it requires 200CFM to operate, then you need a compressor which can deliver 400CFM FAD (Free Air Delivery) otherwise your compressor will be running its heart out (WOT situation  grin )

Also with a Soda setup you need to think about a drier/de humidifier setup otherwise the soda will clog up. DAMHIK

Are you sure on the 200 CFM, that's a hell of a lot of air. I have never seen over 65 CFM personally. Most compressors range in the 15-25 area.

The inside diameter of the soda blaster nozzle will determine how many CFM you need. There should be a chart with the instructions for the machine.

 I think my mate Ashley bought without doing his research.
By the look of delivery pipe we'll need a big industrial compressor.
I get about 5 minutes using the die grinder before the motor kicks in so
I figure my machine won't work. grin

All great advice and I'll pass it on, thanks so much. cheers

It will work, Mike. You will simply have to stop blasting every once in a while to let the compressor build up pressure in the tank. The size of the tank is a factor-- When you first start blasting, a large tank will allow you more time before you need to pause. If you can find a smaller nozzle it would help.

Thanks Neil, Ash bought the unit and asked if I'd get into a little business with him
stripping cars.
 You could do quite well considering what other charge for sand blasting.

He didn't want to take the machine to the body shop where he works as an estimator
because the semi skilled guys there would ruin it in ten minutes.

I have a feeling it won't work too well but he's bringing it around for a test next week.
I would have checked with the manufacturer before buying we'll see.

The shop compressor is in the first pix.  It is a 7 gallon 1/2 horsepower one.  A side spigot is attached so I can hook up an 18-inch long shunt line.

The portable compressor I take to the races is in the second photo.  It is a three gallon 1/2 horsepower job.  The shunt connects to it, like shown, when I want to run them both at the same time.  Then I have a 1 HP 10 gallon compressor.

You might just need a little one and a shunt to get what you need.  The small one is handy to have for other projects when it is a pain to take the big guy.

I have a 5 hp 80 gallon in my shop. If I get carried away in my little Harbor Freight blast cabinet it will run non stop and I have to wait on it to catch up. For all intensive purposes this is about the biggest "common" compressor you can buy at a typical store. Lowe, Sears, etc.

Most "home" style compressors will not have enough CFM to operate a blaster like that for very long (like more than a couple of minutes at best).

We have a 75 HP compressor at work, and two 50 HP compressors.  Just looking at the fittings and "commercial" appearance of that blaster, I'm guesstimating that you would need in the range of 20HP to keep blasting continuously.
