2.1
Operating Principle
The machine works on the one-stage, twin-screw pump principle.
Two screw rotors rotate inside the cylinder. The pumped medium is trapped between the cylinder
and screw chambers, compressed, and transported to the gas outlet. During the compression pro-
cess, the two screw rotors do not come into contact with each other or with the cylinder. There is no
need for a lubrication or an operating fluid in the compression chamber.
The COBRA BA is fully air-cooled thanks to an integrated fan in the protective hood.

The machine is intended for the suction of air and other dry, toxic, non-aggressive and non-explo-
sive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the machine
and is permissible only after a consultation with Busch.

The machine is suitable for continuous operation but limited to a suction pressure of
≤
150 hPa abs.
