MAINTENANCE ACTIVITIES
DANGER
Danger to life due to defective, dismantled and manipulated protective devices
WARNING
Danger from hot components
NOTE
Wear suitable PPE
NOTE
For a description of the safety instructions, see 2.9
The safety instructions must be observed:
• Use appropriate tools and handle with care.
• Personal protective equipment must be used to prevent injury from tools or components.
• The maintenance area must be kept clean and tidy. Objects lying around can be a tripping hazard
• If there is any uncertainty, consult the supervisor or the manufacturer.
The maintenance plan provides for the following activities:
8.4.1
CLEAN FILTER
The rotary valves used are essentially made of graphite and are subject to wear, which is reflected in the form of
carbon dust in the process air. The same interval times must be taken into account here.
8.4.2
CHECK ROTARY VANE
The X series with specially developed sliders achieves improved slider service life due to less abrasion. Attention -
The X series sliders are not compatible with the T series.
Only use original spare parts from Gebr.
Intake filter - F1
Depending on the degree of contamination of the intake air, the filter
cartridge will become clogged. It must be cleaned with compressed air
at the intervals mentioned above, but at least every 200 hours.
During cleaning, wear protective goggles and an FFP2 mask
according to EN 149:2008.
C separator filter - F2 (optional)
The rotary valves used are essentially made of graphite and are
subject to wear, which is reflected in the form of carbon dust in the
process air. The same interval times must be taken into account
here.
Intake filter - F3 (DSK variant only)
The pump generates pressure and vacuum simultaneously. If there is a
greater difference (a lot of pressure, little vacuum), the required air is
drawn in via a second intake (bypass) and cleaned by the additional
intake filter.
The filter cartridges are installed behind the front cover, which is fastened
with 3 Allen screws (A). Loosen them, remove the filter cartridges and
blow them through with compressed air from the inside to the outside.
If the filters are limited in their function (clogged, oily, greasy or
damaged) even after the cleaning process, they must be replaced.
For cleaning, remove the pre-filter from the actual intake filter and blow
off both filters with compressed air.
