2.1 Operating Principle
The machine works on the claw principle.
The MINK is fully air-cooled thanks to an integrated fan in the drive unit.
2.2 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic
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 Busch.
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 underrun.
The machine is suitable for continuous operation.
In order to avoid reverse rotation after switching off, the machine is equipped with a
non-return valve (NRV).
Note: The non-return valve (NRV) is no reliable means to prevent suction and shall
not be used as a non-return valve or shut-off valve for the system.
In case the machine shall be maintained after shutdown:
• Provide an additional manual or automatic operated non-return valve in the suction
line.
Permitted environmental conditions, see Technical Data [ ► 21] .
2.3 Start Controls
The machine comes without start controls. The control of the machine is to be
provided in the course of installation.
The machine can be equipped with a soft-starter.
2.4 Standard Features
2.4.1 Vacuum Relief Valve
The ultimate pressure is limited by a vacuum relief valve. The vacuum relief valve is
adjusted ex-works to the minimum permitted ultimate pressure (see nameplate).
