Home sandblaster for 2.5hp/9.6cfm compressor?

[VeeReihenmotor6]

Hi,
Can anyone recommend a sandblaster that would work for small home projects for my compressor?

May well be trying to achieve the impossible as it isn't great for airtools generally.

Alternatively any standalone diy style sandblasters would be good to hear.

Cheers

To add this was something I was looking at - my compressor specs do fall into the lower range required but don't want to waste £130 if it is going to be pants.

Blasters usually require a high volume of air at a sustained high pressure which small compressors are usually incapable of delivering.

Your compressor says it displaces 9.6cfm.
AFAIAC using the displacement figure is a con which leads people to believe the compressor is more powerful than it really is.
The important figure is Free Air Delivery & that will be around 1/2 to 2/3 of the displacement figure.

I doubt your compressor will be up to it, but ask the supplier.

I suspect you would be better off getting a catapult to fire the sand at the parts with.

Sorry for the sarcasm, but no it won't work.

Even if you are technically within the spec required, you will be nowhere near with that compressor.

You want around 100 psi for sand blasting, and 10 - 20 cfm for a small DIY setup.

Don't take the compressure CFM figures at face value. They're usually quoted as the maximum flow rate at no pressure. Divide that by a factor of ten or so to guess the flow rate at 100 psi. In other words that little compressor may be good for 1 cfm at 100 psi if you're lucky. That's about 5 - 10% of what you'd need for a small sand blasting setup.

I have run a blaster like that from the kind of compressor the OP describes - the way the blaster acts as its own air tank helps, but it does run out of puff and you can't use it continuously for any length.

So it rather depends what your demands will be. For small bits and patient use, it works fine.

Cheers Dave, that's good to hear. I had read that type of sandblaster was good for lower power compressors. I don't mind being patient, I really just want to clean small engine fastners at my leisure and a couple of larger items now and again. I don't mind if it takes time - just want to get surface rust off where wire wheels can't go. Do you reckon that sort of use is doable?

I may well upgrade the compressor one day.

I use a small compresser with a 200ltr supplementary tank which works OK.

Yes, I think you'll be fine for that.

One thing to consider for fasteners etc is a vibratory bowl, which is much slower but decidedly less messy and noisy.

Great tip on the bowl, I did not know such a thing existed. That could be perfect and save a hell of a lot of mess.
