The applicable national regulations must be complied with.
This instruction applies to all models: Comply with the applicable national regulations
for type class of the cabinet.

7. VENTILATION

All safety cabinets have an air intake spigot and an air outlet spigot. The exhaust air
duct (suction side, spigot diameter see Appendix) is connected to the air outlet spigot.
The exhaust air duct conveys the exhaust air to a non‑hazardous area outside the
building. The intake air is drawn from within the installation area. Please refer to the
nationally applicable rules, regulations and laws regarding the specified number of
changes of air and the ducting of the exhaust gas. The function of the ventilation must
be tested at regular intervals (see the section "Servicing").
Safety cabinets to EN 14470‑1 can also be operated without technical exhaust air (for
Germany this means compliance with TRGS‑510 and also the relevant nationally appli‑
cable rules, regulations and laws).
Please note the following points regarding operation without technical exhaust air:
ɽ To avoid the build‑up of electrostatic charges, the cabinets must be effectively earthed.
ɽ An area within a radius of 2.5 m around the safety cabinet and up to a height of 0.5 m
above the floor is considered to be a zone 2 explosion hazard area.
ɽ As required by the Accident Prevention Regulations (BGV A8), provide notices clearly
identifying the zone 2 explosion hazard area using the following warning symbol:
The position of the air intake and outlet spigots are shown in Appendix (see sketch).
