Can An Inexpensive Blast Cabinet be a Good Tool?

Can An Inexpensive Blast Cabinet be a Good Tool?

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.

What is a blasting cabinet dust collector?

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:

How Important is a Separator Reclaimer?

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.

3 Potential Issues with an Inexpensive Blast Cabinet

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:

  1. Less costly cabinets often clean at a very slow rate. This is because they produce very low frictional heat and use smaller gun sizes. Operators must run inexpensive cabinets longer to clean a part than they would in a more powerful machine.
  2. Dust collector maintenance means halting your work. It’s important to consider how often you’ll want to stop blasting to clean your dust collector. This is one of the more expensive components on a blast cabinet, and cheaper machines often cut corners on the dust collector to bottom out on price.
  3. Often low cost blasting cabinets are not made by the same manufacturer from year to year resulting in high wear parts that are hard to replace when you want and need them.

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!

Something Else to Consider

Abrasive blasting cabinets are addicting. Once you see how well your cabinet works, you’ll find all kinds of reasons to use it. Here are just a few:

  1. Removing paint, rust, and dirt without damaging the infrastructure
  2. Surface etching glass (makes for great personalized gifts!)
  3. Drilling holes in glass or tiles or tempered glass
  4. Restoring old tools
  5. Applying tungsten disulfide coatings
