DANGER
Risk of explosion by venting with air.
Depending on the application, venting can cause explo‑
sive mixtures to form or other hazardous situations to
arise.
>
>
Never vent processes with air which could form an
explosive mixture.
>
>
In the case of flammable substances, use
only inert gas for venting, e. g., nitrogen
(max. 1.2 bar/900 Torr abs.).
The diaphragm pump and controller have
no
direct ventilation
connection. You can connect different venting valves, e. g., the
supplied
VACUU·SELECT
®
Sensor
with integral venting valve.

Alternatively you can use a larger valve,
e. g., a
VB M‑B
(#20674217) for faster
venting.
