2.1 Operating Principle
The machine with tri-lobe rotors work on the principle of oil-free gas transport.
Two identical lobes rotate in opposite direction in the casing, transporting fixed volume
of air with each turn. There is no contact between the rotors and also between rotor and
casing, therefore process does not require oil in the working area. The machine trans-
ports the gas without increasing the pressure.
Gas is compressed in the machine outlet by the gas that has already transported (blowers
with external compression).
2.2 Application
The machine is intended for transport of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is suitable for continuous as well as intermittent operation.
Permitted environmental conditions, see Technical Data [►31].
NOTICE
Chemical compatibility of the process gases with the machine component materials.
Risk of corrosion inside the blower working area which can reduce performance and its
lifetime!
• Check if the process gases are compatible with those following materials:
- Cast iron
- Steel
- Aluminium
- Fluoroelastomer (FKM/FPM)
• In doubt, please contact your Busch representative.
