Chemistry Roots pump vacuum unit VACUUBRAND

The combination of oilfree chemistry diaphragm pumps with roots pumps allows for a pumping unit series with greatly increased pumping speed and an ultimate vacuum that is improved by one order of magnitude in comparison to diaphragm pumps. VACUUBRAND roots pumping units distinguish themselves with high specific corrosion-resistance. Due to the dry, oilfree operation and high pumping speed especially in the pressure range of 50 - 0.2 mbar the roots pumping units can pump large quantities of vapour.

VARIO roots pumping units have automatic workload-dependent motor speed control. This allows for operation also at high pressure levels (> 50 mbar) with limited heat release.
