How do you actually vacuum ... blasting material?

With heavy equipment. This is because the material, which is usually in the form of beads, inevitably has to have a certain weight in order to remove layers of paint or corroded residues from steel components, for example.


High performance for heavy-duty operation

This is why a company that refurbishes components for the shipping industry uses a particularly powerful vacuum cleaner from the Ruwac programme. Rust as well as algae and mussels are removed with the blasting system, which works with steel balls. Because the components are very large, this does not take place in a cabin, but in a specially equipped hall.

This means that the blasting material, which is often shattered when steel (shot) hits steel (component), is deposited on the hall floor together with the removed deposits and must be removed from there. This is where a Ruwac DA 5150 M comes into play, which was developed from the ground up for such "heavy duty" applications. This applies to the suction power, which is correspondingly high, and also to the ability to pick up heavy and/or abrasive suction material. In addition, the solid sheet steel housing is also very resistant to mechanical stresses.


Disposal of large quantities

Another feature is the disposal of large quantities: The central filter/separator unit of the DA 5150 M can be adjusted in height and thus adapted to different disposal containers. As the application described here produces large quantities of heavy suction material after each blasting process, a drum with a stable trolley is used, which can be emptied using a tilting device if required.

The extraction system is equipped with an equally robust pre-separator. The direct drive of the side channel blower creates the conditions for high energy efficiency. The dust class M filter unit retains not only blasting material but also finer dusts, and various hoses also connect the central extraction system to sources of dirt and dust in other halls of the company.
