Correct use
CAV terminal units of type EN-Ex are used for con-
stant volume flow control in ventilation and air con-
ditioning systems. They can be used for supply air
and extract air systems in the following areas with
potentially explosive atmospheres:
II 2G Ex h IIC T6 Gb
II 2D Ex h IIIC T80 °C Db
Do not use the CAV terminal unit with an electric
actuator!
In kitchen exhaust air systems, CAV terminal units
may only be used if it is ensured that the extract
air is cleaned as well as possible by highly effective
aerosol separators, observe VDI 2052.
Installation in humid rooms and rooms with dust-
laden or aggressive air has to be assessed individu-
ally.
