Blast Cabinet

Suction

A suction blast cabinet is mostly used for light production jobs, and general cleaning of parts and objects. A suction cabinet works by using a suction gun to pull blast media through a hose, and deliver that media to a blast nozzle, where it is then propelled at great speed into the cabinet. Suction blast cabinets are easier to set up, but it takes more blasting pressure to achieve maximum abrasive impact. Because of this, suction blast cabinets will leave a less pronounced anchor pattern than a direct pressure cabinet using the same blast media.

Lightweight Media

Manual abrasive blast cabinets that remove coatings—without damaging the surface being blasted. Perhaps this is required for inspection of fatigue points on high stress areas of aerospace components, or for cleaning automotive engine and body parts. Lightweight-Media blast cabinets are specifically designed to blast with lightweight, nonaggressive media such as plastic or sodium bicarbonate.

Pressure

A pressure blast cabinet uses a pressurized vessel (like a pressure pot) filled with blast media, which is then forced through a blast nozzle. Pressure blasting is significantly faster and more aggressive than suction blasting. For tough cleaning jobs, pressure blasting delivers higher abrasive velocity for greater impact intensity, compared to suction blasting, and can increase your production rate by as much as 300 percent.
