Abstract (en)
[origin: WO2008022916A1] A process gas (38), possibly comprising reactive particles (40), is suctioned into a vacuum pump device. Oxygen in form of air or pure oxygen is supplied in a controlled manner via an oxygen intake (26, 26a, 26b) into the vacuum pump device. Controlled oxidation thus takes place in the compression chamber (24) such that the dust cannot self-ignite in case of sudden ventilation.
