The basic prerequisite for safe working is to comply

The local regulations for health and safety at work
and general safety regulations also apply.

Correct use

CAV controllers of the type EN are used for con-
stant volume flow control in supply and extract air
ducts of ventilation and ventilation systems.

Do not use CAV controllers in extract air systems in
commercial kitchens unless the extract air has been
cleaned as much as possible with high-efficiency
aerosol separators; see VDI 2052.

The installation of air terminal devices in humid
rooms, areas with potentially explosive atmos-
pheres or rooms with dust-laden or aggressive air
has to be assessed for each individual case.
