Choosing the Rated Speed:
The rated speed should be set to correspond to the volume to ventilate or the surface area of the
premises.
For the Cube model:
Surface area of the
space to ventilate* (m²)
0 to 12
12 to 48
48 to 60
60 to 66
66 to 76
76 to 84
84 to 108
108 to 136
136 to 152
152 to 160
For the Urban model:
Surface area of the
space to ventilate* (m²)
0 to 24
25 to 48
49 to 56
57 to 65
66 to 75
76 to 88
89 to 102
103 to 118
119 to 138
139 to 160
The above data comes from measurements made in a laboratory, so discrepancies with these
measurements may be observed.
* for premises with an unchanging ceiling height of 2.5 m.
