2. Machine description 

 
The 

Blastrac

  blast  cleaning  machine  2-20DT  is  a  downward  blasting  machine  with  a  closed  abrasive  circuit 

exclusively  designed  for  the  pre-treatment  of  dry,  frost  free  horizontal  surfaces.  The  bouncing  impact  of 
metallic  abrasive  onto  the  surface  to  be  treated  thoroughly  removes  surface  contaminants,  coats  of  paint, 
sealants and thin coatings. The intended use of this machine is blast cleaning of the following surfaces: Steel, 
concrete, stone and asphalt. The machine may not be used for other purposes. The manufacturer will not be 
liable for damage resulting from incorrect usage, in these cases the user assumes all risks. 
A  suitable  filter  unit  must  be  connected  to  the  machine  in  order  to  separate  the  dust  from  the  abrasive.  A 
specially designed Blastrac dust collection system ensures dust-free operation of the machine and clean air at 
the workspace.
