Instruction Manual R5 PB 0003 D_EN_en 5 | 28
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 solids from entering, the machine is equipped with an inlet screen (IS).
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 damages to the machine!
Risk of damages to the environment!
●Make sure to follow all instructions described in this manual.
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic and non-ex-
plosive 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 capable of maintaining ultimate pressure, see Technical Data [➔23].
Permitted environmental conditions, see Technical Data [➔23].
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 starter unit or a variable speed drive.
The machine can be equipped with a soft-starter.
2.4 Standard Features
2.4.1 Motor Thermal Protection
Single-phase motors are equipped with a thermal protection switch to protect the machine against
overload. Three-phase motors are not equipped with a thermal protection switch.

3 | Transport
6 | 28 Instruction Manual R5 PB 0003 D_EN_en
3 Transport
NOTICE
In 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 immedi-
ately 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 [➔23] or the name-
plate (NP).
●Check the machine for transport damage.
If the machine is secured to a base plate:
●Remove the machine from the base plate.

Storage | 4

4 Storage
●Seal all apertures with adhesive tape or reuse provided caps.
If the machine is to be stored for more than 3 months:
●Wrap the machine in a corrosion inhibiting film.
●Store the machine indoors, dry, dust free and if possible in original packaging preferably at
temperatures between 0 ... 40 °C.

Instruction Manual R5 PB 0003 D_EN_en 9 | 28
●Contact your Busch representative, the motor should be derated or the ambient temperature
limited.
5.2 Connecting Lines / Pipes
●Remove all protective covers before installation.
●Make sure that the connection lines cause no stress on the connection of the machine; if neces-
sary use flexible joints.
●Make sure that the line size of the connection lines over the entire length is at least as large as
the connections of the machine.
In case of long connection lines, it is advisable to use larger line sizes in order to avoid a loss of effi-
ciency. Seek advice from your Busch representative.
5.2.1 Suction Connection
NOTICE
Ingress of foreign objects or liquids.
Risk of damage to the machine!
If the inlet gas contains dust or other foreign solid particles:
●Install a suitable filter (5micron or less) upstream from the machine.
Connection size(s):
– G1/8
Depending on the specific configuration ordered, other connection dimensions may apply.
5.2.2 Discharge Connection
CAUTION
The discharge gas contains small quantities of oil.
Risk to health!
If air is discharged into rooms where persons are present:
●Make sure that sufficient ventilation is provided.
NOTICE
Discharge gas flow obstructed.
Risk of damage to the machine!
●Make sure that the discharged gas will flow without obstruction. Do not shut off or throttle the
discharge line or use it as a pressurized air source.
Connection size(s):
– Without connection. The discharged gas is released to the ambient of the machine.
Depending on the specific configuration ordered, other connection dimensions may apply.

The maintenance intervals depend very much on the individual operating conditions. The intervals
given below are considered as starting values which should be shortened or extended as appropri-
ate. Particularly harsh applications or heavy duty operation, such as high dust loads in the environ-
ment or in the process gas, other contamination or ingress of process material, can make it neces-
sary to shorten the maintenance intervals significantly.
Interval Maintenance work
Weekly ●Check the oil level, see Oil Level Inspection [➔15].
●Check the machine for oil leaks - in case of leaks have the
machine repaired (contact Busch).
Monthly In case of an inlet filter being installed:
●Check the inlet filter cartridge, replace if necessary.
Every 2000 hours or every 6
months
●Change the oil and the exhaust filters (EF).
Every 5 years ●Have a major overhaul on the machine (contact Busch).
