Abrasive Blasting 101
Updated February 2022: When deciding which abrasive blast cabinet to buy and how much money you’ll spend, it’s likely you’re asking yourself if you can make do with an inexpensive blast cabinet.
Inexpensive blast cabinets typically come with fewer machine features, a smaller dust collector storage area, decreased blower air movement and increased maintenance needs. It’s very rare these cabinets include a separator reclaimer to clean the abrasive as it’s recycled. As a result, your recycled abrasive is reused along with anything removed from the part being cleaned – paint, dirt, etc.
The dust collector on any blasting cabinet is the most important feature. When the dust collector fails the mess then gets out of control. If you want to educate yourself more about dust collectors, we recommend reading the following:

That’s up to the operator’s discretion. Using a machine without one means rather than recycling abrasive over and over, you have to throw it away to maintain visibility. Not having a separator reclaimed would be comparable to not having an oil filter on an automobile – it’s possible to do, but you’re going to have to change your oil more frequently.
Are low-cost blasting cabinets a bad investment if they are simply a cabinet, trigger gun, vacuum blower and a light bulb? Consider these three potential problems:
ProTip: If you have a larger compressor know that using a gun with two times the cfm flow will blast the parts in 1/3rd the time, double again and it’s 1/9th the time. This continues because while almost all cabinets blast at 80 psi, siphon delivery and not pressure pot delivery, the increased frictional heat created by a larger gun delivering more abrasive really shortens blast time. If you are cleaning nine times faster you want a much larger dust collector – which is always missing from a low-cost cabinet!
