My Personal Setup

I personally have installed a pressure style blast cabinet in my home garage shop, specifically the PSBC990 from Atlas. I chose this unit for its ability to maximize the blasting power of my already installed air compressor system, my available square footage in my garage, and the cabinet dimensions to fit what I most commonly expect to sand blast, such as wheels, subframes, and suspension components.

I also wanted something that did not require a large swinging door, so this unit is front loaded with a shock assisted upward folding door. As you can see, the inner dimension is fairly large!

My unit is paired with my 80 gallon, 5hp, 2 stage, 220v Ingersoll Rand air compressor with roughly ~16 CFM at 90psi. This air compressor is, in my opinion, the SMALLEST you would want for a sand blast cabinet of this size. I do also have PEX lines plumbed throughout my garage with a few retractable hoses and a few direct lines feeding my blast cabinets (I also have a vapor honing machine that requires air).

Take care in thinking through your future layout, not just what you have today but what you plan to need or want in the future and the space constraints you are working with today. In my case, I knew I would need a large amount of air and power. Remember this when you lay out your home shop. As you can see, they are both rather large, and take up a significant amount of prime real estate in the garage.
