8 Description
2.2 Function
An electrically operated diaphragm pump generates
the vacuum necessary for aspiration.
The appliance can optionally be powered by a re-
chargeable internal power pack or can also be sup-
plied by an external direct voltage source with 12.0
- 13.8 V.
Use the vacuum control to set the desired vacuum,
which is continuously variable between –0.05 bar
and –0.8 bar. You can read off the set value on the
pressure gage.
The aspirated material passes through the aspiration
tube into the collection canister.
Re-usable collection canister
The re-usable collection canister is fixed to the side
of the motor unit and directly connected to the suc-
tion port of the motor unit.
A replaceable hydrophobic bacteria filter in the
secretion cover prevents bacteria and droplets of
moisture from finding their way into the motor unit
and passing into the environment via the muffler.
The bacteria filter is designed for multiple re-use and
sterilisation.
Important Do not immerse the bacteria filter in disinfectant liq-
uid, as this adversely affects its hydrophobic proper-
ties.
