Data sheet
Calculating damper blade excess lengths:
•
Ü1 = ½ · H - L1 + 105 mm; Ü2 = ½ · H - L2 - 107 mm
•
If Ü1
≤
0 or Ü2
≤
0, there is no damper blade excess length!
If protective grilles are mounted directly on the casings
,
then Ü1 or Ü2 should be at least -20 mm, which equates to a
20-mm freedom of movement. Hence,
L1
≥
½ · H + 125 mm
and
L2
≥
½ · H - 87 mm
should be applied!
L2
≥
W(D) + Z is also necessary!
Here,
W
= thickness of the wall,
D
= thickness of the ceiling.
Z
is the
necessary casing excess
length.
