Preface
Congratulations on your purchase of the Busch side channel blower.
With watchful observation of the field’s requirements, innovation and
steady development Busch delivers modern vacuum and pressure solu-
tions worldwide.
These operating instructions contain information for
–product description,
–safety,
–transport,
–storage,
–installation and commissioning,
–maintenance,
–overhaul,
–troubleshooting and
–spare parts
of the side channel blower.
For the purpose of these instructions, “handling” the side channel
blower means the transport, storage, installation, commissioning, influ-
ence on operating conditions, maintenance, troubleshooting and over-
haul of the side channel blower.
Prior to handling the side channel blower these operating instructions
shall be read and understood. If anything remains to be clarified
please contact your Busch representative!
Keep these operating instructions and, if applicable, other pertinent
operating instructions available on site.

Product Description
Use
The side channel blower is intended for
–the suction
–the compression
of
–air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a lower or higher density than air leads to an in-
creased thermal and/or mechanical load on the side channel blower
and is permissible only after prior consultation with Busch.
The gas shall be free from vapours that would condensate under the
temperature and pressure conditions inside the side channel blower.
The side channel blower is intended for the placement in a non-poten-
tially explosive environment.
The side channel blower is suitable for continuous operation, provided
that the housing can transmit heat to the environment without ob-
struction and a certain minimum gas transfer is warranted. If there is a
risk that the side channel blower may be operated against a closed inlet
or outlet for more than a few seconds, a vacuum or pressure relief
valve, respectively, shall be provided. Frequent switching on and off
leads to increased coil temperatures. In case of doubt seek advice from
your Busch representative!
The maximum allowed pressure on the pressure connection (d) is
2 bar abs. By means of process control and/or pressure relief valves it
must be made sure that the maximum allowed pressure will not be
exceeded.
Principle of Operation
The side channel blower works on the impulse principle, i.e. kinetic en-
ergy is transferred from the rotor to the conveyed medium and then is
converted into pressure.
For the two stage version:
2 stages, both working on the principle described above, are installed
in line in order to achieve a better ultimate/differential pressure.
The side channel blower compresses the inlet gas absolutely oil-free.
A lubrication of the pump chamber is neither necessary nor allowed.
Cooling
The side channel blower is cooled by
–radiation of heat from the surface of the side channel blower
–the air flow from the fan wheel of the drive motor
–the process gas
Start Controls
The side channel blower comes without start controls. The control of
the side channel blower is to be provided in the course of installation.

Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere, fre-
quent temperature changes) conserve the side channel blower immedi-
ately. In case of favourable ambient conditions conserve the side
channel blower if a storage of more than 3 months is scheduled.
●Make sure that all ports are firmly closed; seal all ports that are not
sealed with PTFE-tape, gaskets or o-rings with adhesive tape
Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in mo-
lecular thickness on the packed good and by its electro-chemical prop-
erties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! Busch uses CORTEC
VCI 126 R film for the overseas packaging of large equipment.
●Wrap the side channel blower in VCI film
●Store the side channel blower
–if possible in original packing,
–indoors,
–dry,
–dust free and

Controlling Pressure/Flow
Vacuum operation:
●In order to relieve excess vacuum or to limit the air flow use vent
valves. Do not control the vacuum or the flow by throttling of suc-
tion or discharge lines. Conveying bypass air will let the side
channel blower run cooler and draw less power.
Pressure operation:
●In order to relieve excess pressure or to limit the air flow use bleed
valves. Do not control the pressure or the flow by throttling of suc-
tion or pressure lines. Bleeding excess air will let the side channel
blower run cooler and draw less power.
