Max. permissible dynamic load of the G-BH100 due to vibrations from outside:
Vibration frequency Vibration value
< 6.3 Hz Vibration displacement s ≤ 0.16 mm
6.3 Hz ... 63 Hz Vibration velocity v
eff
≤4.5 mm/s
> 63 Hz Vibration acceleration a ≤ 2.55 m/s²
2 Surface sound pressure level (EN ISO 3744), measured at a distance of 1 m [3.28 ft] at an operating point of ap-
prox. 2/3 of the permissible total differential pressure with the pipes / hoses connected and without vacuum or
pressure limiting valve.
3 Permitted only with: unobstructed cooling ,
an operating voltage of 24 V ,
a speed reference value of 10 V and
left-handed rotation of the G-BH100.
The indicated temperature refers to the gas intake temperature. It is assumed that the gas intake tem-
perature equals the ambient temperature of the
G-BH100.
IMPORTANT: For the max. permissible total differential pressure at temperatures other than +15°C
[+59°F]see
"Fig. 3", page 9.
In case of increased throttling inside the suction or delivery pipe a pressure relief valve must be provided .
In case of reduced speeds by means of a lower speed reference value the max. permissible total differ-
ential pressures change as well
.
4 Vacuum operation: extraction of air
having the indicated temperature at the suction branch and a pressure of 1013 mbar
at the delivery branch
.
5 Compressor operation: compression of air
having the indicated temperature at the suction branch and a pressure of 1013 mbar
at the delivery branch
.
6 Max. permissible speed due to the mechanical components and the design of the unit.
7 For: operation within the permissible operating range ,
the max. permissible dynamic load due to vibrations from outside and
fastening by means of rubber / metal elements (available as accessories).
