Operating Instructions
Radial Compressors
Safety Regulations
Please comply with Accident Prevention Regulations
VBG 16 Compressors, in particular Section IIIc
"Installation" and IV "Operation" and VBG 4 "Electrical
Installations and Equipment".
Alterations to the radial compressors may be effected
only after agreement by the factory.
Air compression will generate high temperatures at
the radial compressors:
- Install compressors in a position where hot surfaces
cannot be touched
- Or protect the area around them
- Or install warning signs.
Application
Radial compressors are used for the generation of
overpressure. Their characteristics apply up to a
height of 800 m above sea level.
When operating radial compressors, ensure that
only normal atmospheric air can be taken in.
Transport and storage
Store radial compressors in a dry place and protect
against condensate through water vapour.
Lift and transport with cranes only by using the ring
screws.

Installation
It is recommended to install the radial compressor
with easy access for maintenance.
Clearance between compressors and adjacent walls
should be no less than 10 cm of free space in order
to ensure sufficient air flow for cooling. Contact
Gebrüder Becker prior to installation under noise
insulation canopies.
Ambient temperatures must not exceed
45°C.
Assembly
Ensure correct dimensions (vs. table) of and clean
pipelines (no weld spatter, chips or similar
contamination).
Keep connections free from oil, grease, water and
other contaminants.
Remove end caps at DA and SA. Do not connect to
pipeline yet.
Motor connection
Connect radial compressor to the electricity supply
observing all applicable safety regulations. Comply
with EN 60204 T1.
Connect motor based on connecting diagram (in
terminal box) or ready-made plugs. This work should
be carried out by an experienced electrician only.
Check for connecting voltage and frequency.
Install motor circuit-breaker and set to nominal motor
current. (For data see motor rating plate).
Avoid switching of more than 10 times per hour.
Briefly start motor and check rotation (arrow on
casing). Exchange phases if rotation is incorrect.
Commissioning
Connect pressure line at DA.
Loud swinging sounds in the presure line indicate
insufficient taking-off of air. Adjust machine to take-
off more air or bleed-off air via an additional tap.
Maintenance
Regular maintenance of your radial compressor will
yield the best results. Maintenance intervals will
depend on use and operating conditions.
Before carrying out any maintanance, disconnect
motor from mains and reliably prevent unintentional
restarting.
The filter cartridges are mounted behind the casing
covers GD and have to be cleanned depending on
dust ratio. Blow out filter by compressed air from
inside to outside.
Blocked, oily or greasy cartridges must be replaced.
Blow out contaminations at the surfaces and the
motor fan using compressed air.
Exchange warm gear box oil (vs. table) initially
after 200 operating hours. Subsequently exchange
oil after 2.000 operating hours but at least once a
year.
Clean fan hood and compressor surfaces to prevent
overheating.
