Extra power when your dust collection system needs it

RBU roots pump high vacuum unit

As standard supplied with vacuum and discharge silencers, universal valve including vacuum regulator, safety valve and back flusch valve. Inlet diam. 200 mm. (8 in.) discharge at diameter 200 mm. (8 in.) Applications: cleaning, sqwarf removal, grinding, sanding, welding. Also in instlalations where extra extraction power is needed, e g heavy material or long piping system. Extra power is required when larger and heavier pieces need to be taken care of or need to be transported through long pipelines. Nederman RBU units work uninterruptedly with strong suction and a maintained efficiency. This is the perfect vacuum source in larger systems where powerful vacuum is required to balance for large pressure drop in long pipes or hoses. Many of the Nederman RBU units can operate continuously at -45kPa / 180 in. W.G. and are the optimal vacuum source for heavy cleaning and heavy on-tool extraction. The unique quality of the RBU unit is the combination of an extraordinary suction capacity and a low noise level. This is due to successful design with a 3-lobe roots type blower fitted with unique inlet and outlet silencers, all housed in a heavy insulated acoustic enclosure.
