Surface preparation with an abrasive sandblaster is the operation of forcibly propelling a stream of abrasive material (i.e glass beads, korunt, steel grit, etc) against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants such as paint or rust.
One of the main challenges in any surface preparation operation with a sandblaster is to keep the
blasting media from contaminating the surrounding work environment.
Surface preparation needs to be carried out in an enclosure. This is
most often done in a dedicated blasting room, separated from other
operations, so work pieces need to either be moved to
and from the blasting room, or encapsulated, leading to increased
Surface preparation with vacuum sandblasters
The Nederman vacuum sandblasters are productivity boosters, thanks to the design of the vacuum head along with the continuous, non-pulsing stream of the blasting abrasive. You'll cover larger surfaces faster and save money with less downtime and abrasive costs. With the vacuum sandblasters you can operate continuously and re-use the same abrasive several times, depending on the type of abrasive. During the surface preparation the Vacuum sandblaster collects the dust in plastic bags. Efficient pre-separation of abrasive with automatic reverse air jet filter cleaning provides for long lasting filters.
