Roots pump vacuum unit
max. 45 kPa, max. 3200 m³/h | RBU series NEDERMAN

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.
Reliable in operation
Our RBU units are equipped with a highly efficient roots type
pump with safety functions such as temperature control, safety
valve, back flush valve etc. Other features contributing to reliability
are gears in an oil bath and a generously dimensioned motor.
Higher efficiency gives lower energy costs
When vacuum is stronger than -30 kPa / 120 in. W.G., the RBU
has 30-35% higher efficiency compared to centrifugal fans or
side channel fans (turbo pumps). This gives effective suction at a
lower cost.
