Instruction Manual R5 RA 0063 F Compact_EN_enProduct Description​ | 2

2.1

Operating Principle

The machine works on the rotary vane principle.
The oil seals the gaps, lubricates the vanes and takes away compression heat.
In order to avoid reverse rotation after switching off, the machine is equipped with a non-return
valve (NRV).
In order to avoid solids from entering, the machine is equipped with an inlet screen (IS).
The oil filter cleans the circulating oil.
Exhaust filters separate the oil from the discharged gas.

2.2

Intended Use
WARNING
In case of foreseeable misuse outside the intended use of the machine.
Risk of injuries!
Risk of damage to the machine!
Risk of damage to the environment!
● Make sure to follow all instructions described in this manual.
The machine has a compact oil separator and is designed for the installation in a chamber packaging machine at max. 50 Hz.
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic, non-ignitable 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 designed for indoor installations. For outdoor installations, consult your Busch representative for special precautions.
The machine is capable of maintaining ultimate pressure, see Technical Data [➔ 29].
Version with float valve (standard):
The machine is suitable for continuous operation.
Version with oil return valve:

Instruction Manual R5 RA 0063 F Compact_EN_en

5 | 36

2 | Product Description​
During operation oil accumulates at the bottom of the upper chamber of the oil separator,
which cannot flow down into the bottom chamber, as long as the machine runs. After 10 hof continuous operation near ultimate pressure, in case of operation in rough vacuum, after
a shorter time:● The machine must be shut down for at least 15 min➔

The oil can run down from the upper chamber of the oil separator into the bottom
chamber.

The machine is suitable for continuous operation up to 100 mbar.
Permitted environmental conditions, see Technical Data [➔ 29].

2.3

Start Controls
The machine comes without start controls. The control of the machine is to be provided in thecourse of installation.
The machine can be equipped with a soft-starter.

2.4

Optional Accessories

2.4.1

Gas Ballast Valve
The gas ballast valve mixes the process gas with a limited quantity of ambient air to counteract thecondensation of vapor inside the machine.
The gas ballast valve has an influence on the ultimate pressure of the machine, see Technical Data[➔ 29].

2.4.2

Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The inlet filter
is available with a paper or polyester cartridge.

2.4.3

Level Switch
The level switch monitors the oil level in the oil separator (OS).

WARNING
Suspended load.
Risk of severe injury!
● Do not walk, stand, or work under suspended loads.

WARNING
Lifting the machine using the motor eye bolt.
Risk of severe injury!
● Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine as shown.

NOTICEIn case the machine is already filled with oil.
Tilting a machine that is already filled with oil can cause large quantities of oil to ingress into
the cylinder. Starting the machine with excessive quantities of oil in the cylinder will immediately break the vanes and ruin the machine!
● Drain the oil prior to every transport or always horizontally transport the machine.
● To find out the weight of the machine, refer to the chapter Technical Data [➔ 29] or the nameplate (NP).
● Make sure that the eye bolt(s) (EB) is/are in faultless condition, fully screwed in and tightened byhand.

● Check the machine for transport damage.
If the machine is secured to a base plate:● Remove the machine from the base plate.
