Vacuum blasting
In vacuum blasting, the dust and abrasive is immediately sucked back from the surface within a brush head. In this way, dust-free blasting is achieved without causing any nuisance to the surrounding area due to blasting media. However, the working speed is lower than for open blasting and therefore this method is mainly used for spot-repairs, welds and in-situ blasting.
The blast chain
Besides a good blast pot, it is important that the suction unit has the right capacity for the chosen blast media, the blasting pressure and the distance to the object to be blasted. The filter of the suction unit must also be suitable for providing the right vacuum over a long period of time. Gritco units have all these professional features and are further characterised by their simple operation and easy dust removal.
Selecting the right abrasive and grain size are essential aspects to ensure long-term, dust-free operation and an efficient working speed.
The compressor capacity must be matched to the compressed air requirements of both the blast pot and the suction unit (in the case of a fully pneumatic design). It is crucial that the compressed air is dry and clean to avoid blockages and machine problems.
