AwiVac
10.3 Mechanical Connection
There are three mechanical hose connections for 4/6mm on the outer side of the housing of the AwiVac
(optionally, other connection versions are also possible).
- Connection 1: Analysis gas inlet from gas analysis system
- Connection 2: Analysis gas outlet to gas analysis system
- Connection 3: Exhaust air
The exhaust air is usually conducted outside, and this outlet must be designed exactly like in the case of
the exhaust air from the gas analysis system. You can find more information specifically on exhaust air in
chapter (
DANGER
gas may escape from the exhaust gas pipe of the AwiVac during normal operation. This gas may be
combustible and toxic. This may lead to fire, explosion and poisoning. Do not release the exhaust gas
inside the building.
WARNING
The exhaust pipe of the AwiVac is required for a safe pressure limitation. The gas must be able to
drain off. When discharging into closed gas rooms and lines, make sure that 1 l / min does not build
up a pressure of more than 200 mbar in order not to exceed the permissible pressure of 400 mbar on
the integrated precision pressure regulator.
WARNING
Sample gas can escape at the exhaust connection of the AwiVac. When introducing sample gas into
gas-carrying lines, the possibility of creating an explosive atmosphere must be taken into account.
Either feed into an Ex zone 1 or into an area in which the gas flows continuously.
NOTE
The exhaust pipe of the AwiVac is necessary for the pressure limitation. An introduction into areas
with negative pressure interferes with the proper gas flow to the measuring device. The exhaust air
must not be combined with the exhaust air from the gas analysis system.
