NOTE
We have carried out a risk assessment for the Multiboxes. However, it can only apply to the Multibox itself. After
installation of the Multibox, we recommend carrying out a risk assessment of the total sys-tem. In this way, you have
the guarantee that there is no risk potential from the system.

Intended use
The Multiboxes (MUB) are intended for installation in ventilation systems. They can be installed both in channel systems and also with
free suction via an admission nozzle and a suction-side contact protec-tion grid. Free blow-out via a contact protection grid is also pos-
sible following prior consideration dur-ing design.
•
The Multiboxes are suitable for the conveying of clean air, air with a low dust and grease content, media up to a max. air density of
1.3 kg/m3 and an admissible moisture of max. 95%.
•
The maximum admissible operating data on the name plate apply for an air density p = 1.2 kg/m3 (sea level) and a maximum air
moisture of 80%.
•
The multiboxes are suited for the following range of ambient and conveyed goods temperatures:
–
MUB
from -20 °C to +50 °C
–
MUB (UL) from -30 °C to +50 °C
–
MUB/F
from -20 °C to +55 °C, 400° C/120 min
–
