Function principle
With side-channel compressors, the impeller rotates contact-free in the compres-
sor housing.
The conveyed media is suctioned through the inlet (1) and accelerated spirally in
the direction of rotation of the side channel.
The conveyed media is accelerated by the centrifugal force in the radial blades in
the direction of the side channel (2) inner wall, and from there is again supplied to
the impeller (3). As such, the conveyed media is supplied with kinetic energy in the
direction of rotation and the pressure increases.
Due to the reduced cross section on the interruptor, the conveyed media is
stripped from the blades and expelled via the outlet (4).
Side-channel compressors always show a pressure difference and as such, can
be used as vacuum pumps or compressors.

Storage
NOTICE
Mechanical damage and corrosion!
Failure to adhere to the storage conditions can lead to mechanical damage
and corrosion or can shorten the re-greasing interval.
1. Adhere to the storage conditions.
2. The maintenance intervals of the ball bearings (Maintenance [➙38]) become
shorter as the time of storage increases.
1. Connect all suction vents so that no dirt or solid particles can enter.
2. Turn the rotor once per year so as to avoid permanent standstill marks.

Measures after long-term storage
Replace ball bearings and radial shaft seal
!When the length of storage until assembly is exceeded by 4 years for the
storage conditions provided in Storage [➙18].
1. Replace the rolling bearing.
2. Clean adjacent bearing areas for open ball bearings and re-grease.
3. Replace and grease the radial shaft seal.
If the bearing conditions vary (Storage [➙18]), a reduced ball bearing service life
is to be expected.

Value ≤1 kΩ per volt of measured voltage: Dry winding.
Mounting conditions
At the place of assembly,
▪Adhere to the Permitted conditions for use [➙43].
▪No outlet air from other machines in the suction area of the motor fan or auxil-
iary ventilator.
▪Provide ventilation facilities, so that the permissible Maximum temperatures
[➙43] are not exceeded.
▪Sufficient room is provided for installation and removal of pipelines and main-
tenance and repair work, particularly for removing and installing the G-BH8.
▪Even, horizontal and stable installation surface or baseframe provided, whose
dimensions and load-bearing capacity are designed for the G-BH8.
▪The maximum tolerance for the evenness of the assembly surface is 0.5 mm
[0.197 in].
▪External oscillations >1.5 mm/s [0.06 in/s], shock loads, linear or rotary accel-
erations are not permitted.
▪When installing outdoors, protective measures against the effects of weather
such as rain, direct sunlight, lightening, snow or ice (e.g. a protective roof)
must be provided.
▪External mechanical loads are not permitted on the G-BH8 and its attach-
ments (e.g. piping without support, ascending the G-BH8 and its attachments)
▪For installation in enclosed spaces and for conveyed media other than air,
leaks from the G-BH8 must be considered.
▪When operating without silencers and direct extraction from the environment
or direct discharge into the environment, effective noise protection measures
must be provided.
Reduction of oscillations and noises
Noise emissions and vibrations can be reduced by the following measures.
▪Do not set up the G-BH8 in set-up areas that conduct or radiate sound.
▪Equip installation surfaces with intermediate layers of noise damping material.
▪Use additional silencers (accessory).
Always construct the G-BH8 flexibly on spring elements.
