I can tell you a 3 horse is barely enough for blasting.

You will need a pair of them if you want to sustain more than 20 seconds blasting

Most of us are in the same boat.

You want a good size tank, 100 L +

Belt drive.

The best Fad you can get for your money.


My experience, I have a branded belt drive 3hp comp with a 100 L tank and a fad of around 11 cfm. And it runs flat out on a little bench top blast cab, crushed glass as the medium.

It's great for brackets and bits but works the compressor hard.

as above you need 2.

I have a sip 3HP AND a 2hp small compressor (clarke £100) and it lasts 30 mins working.





Thanks

have a look at the water blasting there is a kit on Ebay that attaches to a jet was needs to be above specific pressure though keep the dust down
