A blast cabinet is an enclosed, purpose-built space where the workpiece is blasted safely, with the abrasive automatically recovered and recirculated — without dust and abrasive dispersing into the rest of the workshop. It’s the right solution for parts worked repeatedly, for better process control, and for significantly lower abrasive consumption compared to open-air blasting.

Types of blast cabinets

Choosing a cabinet depends on part size, workload and the desired level of automation:

Manual (glove-box) cabinets — suitable for small and medium parts: the operator works through gloves fitted into the cabinet wall, with visibility through impact-resistant glass, while fallen abrasive is automatically recovered from the cabinet floor and sent back to the gun.
Walk-in cabinets — large enough for the operator to actually walk in with the part, or to blast large parts (metal structures, industrial components), with appropriate respiratory protection equipment.
Automatic turbine cabinets — for series production: the part is loaded through a handling system, and turbines propel the abrasive continuously, with productivity well above manual blasting.
Compressed-air cabinets — simpler and more affordable to invest in, suitable for smaller volumes or parts that vary in shape.

What a blast cabinet is made of

Abrasive recovery and recirculation system — the cabinet floor is angled or fitted with a conveyor that collects fallen abrasive and sends it back into the circuit, through a separator that retains dust and impurities.
Dust filtration / extraction system — maintains visibility inside the cabinet and reduces dust released into the workshop when the door opens.
Interior lighting and impact-resistant glass — for continuous visual control of the process, without stopping blasting.
Part access door — sized according to the dimensions of the parts being worked.

Cabinet vs. open-air blasting

Open-air blasting (without a cabinet) is only possible in specially built enclosures, due to the risks of propelled material and dust. A cabinet solves this by design: it recovers the abrasive (lower cost per part), retains the dust (a cleaner, safer work environment), and allows continuous work regardless of outside conditions.

How to choose the right cabinet

A few practical criteria: the maximum size of the parts you work with determines the cabinet size; production volume decides whether a manual cabinet is enough or an automatic turbine system makes sense; the type of abrasive used influences the required recirculation and filtration system; and available workshop space and budget remain, as usual, the real limits of the decision.

Applications

Blast cabinets are used extensively in auto repair shops (wheels, engine parts, body panels), in restoration workshops, in metalworking for preparing parts before painting or welding, and in series production where finish consistency matters as much as work speed.

The Vibroblast team helps you choose the size, propulsion type (compressed air or turbines) and recirculation system that fit your application.
