Gas disch arge / Pressure connec-
tion
The conveying direction of gases is indicated by an arrow at the
gas inlet or gas outlet.
In case of compressor operation:
• Make sure that the pressure line fits to the pressure connection
of the side channel blower
• Make sure that the pressure connec tion is connected to a
pressure-tight flexible hose or pipe.
In case the side channel blower will be used for pressure applica-
tion and is likely to run against a closed outlet for more than a few
seconds:
•Provide a pressure relief valve.
In case of vacuum operation:
The following guidelines for the discharge line do not apply, if the
aspirated air is discharged to the environment right at the side
channel blower.
• Make sure that the discharge line fits to the gas discharge /
pressure connection of the side channel blower.
Pre parin g of pipe conne ction
When a pipe is connected to the side channel blower appropriate
the connection diameter of the side channel blower, no damage of
the pipe is expected by vibrations of the machine.
• Make sure, that temperat ure-affected longitudinal expansions of
the pipe will be compensated, if necessary use bellows
• Make sure that the pipe will cause no stress on the side channel
blower's connection, if necessary use bellows
• Make sure that the line size of the pressure line over the entire
length is at least as large as the gas inlet / suction connection of
the side channel blower
In case the length of the pressure line exceeds 20 m it is prudent
to use larger line sizes in order to avoid a loss of efficiency and an
overload of the side channel blower.
• Make sure that the discharge line either slopes away from the
side channel blower or provide a liquid separator or a drip leg
with a drain cock, so that no liquids can back up into the side
channel blower.
In case of doubt seek advice from your AIRTECH representative!
Silencer
Single-stage and multi-flow machines are delivered with preassem-
bled silencers.
For multi-stage machines, the pressure-side silencer is supplied
loose for packaging-related reasons and must be installed by the
operator using the supplied fastening material (screws/threaded
bolts and nuts).
Pipe connecting
• Connect the suction line .
• Connect the pressure line .
• Make sure that all provided covers, guards, hoods etc. are
mounted.
• Make sure that cooling air inlets and outlets are not covered or
obstructed and that the cooling air flow is not affected adversely
in any other way.

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
suction 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 suction or pressure lines. Bleeding excess air will let
the side channel blower run cooler and draw less power.
