The system must be connected to an exhaust air system depending on room air and ventilation. In the event of a glovebox operation with a 50l gas cylinder, up to 10,000l of gas can flow into the premises. With a tank supply, however, much more.
If dangerous substances are used, a connection is recommended. The connections should be at the vacuum pump, the purge outlet valve, the regeneration gas outlet, the overpressure protection valves and, if purge valves are used, at their outlet valves. The specification of the exhaust air system is given in the user manual.
