2.1
Operating Principle
The machine works on the impulse principle,i.e. Kinetic energy is transferred from
the impeller to the conveyed medium and then is converted into pressure.
The change in pressure is made without the use of any lubrication whatsoever.
NOTICE
Lubricating a dry running machine (process chamber).
Risk of damage to the machine!
•
Do not lubricate the process chamber of the machine with oil or grease.
2.2
Application
The machine is intended for the suction and/or compression of air and other dry, non-
aggressive, non-toxic, non-flammable and non-explosive 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 GOORUI.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is not capable of maintaining ultimate pressure. The minimum allowed
ultimate pressure is to be read from the nameplate of the machine.
By means of process control and/or vacuum relief valves it must be made sure that the
minimum allowed ultimate pressure will not be under run.
Permitted environmental conditions, see Technical Data [►16].
2.3
Optional Accessories
2.3.1
Pressure relief Valve
The pressure relief valve controls inlet pressure when the machine is used on
vacuum duties.

2.3.2
Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The
inlet filter is available with a cartridge.
2.3.3
Silencer
A silencer at the discharge connection (OUT) can be provided to reduce the exhaust gas
noise.
