I have a skat blast from tp tools. I can do an intake or 15” wheel but that’s about it. I bought mine about 15 years ago and have used it a lot. My compressor is a 2 stage 18 cfm - 23 cfm and it just keeps up. Nozzle size determines cfm. There are times I wish I had gone bigger, but for the most part, it’s the right size.

I think my model was the 780. Just replaced the gloves last year. Also make sure you have a good water separator.
