Explanation of the abbreviations and pictograms
Wn = nominal width
Hn = nominal height
Sn = free air passage
E = integrity
I = thermal insulation
S = smoke leakage
60/120 = fire resistance time
Pa = pascal
o -> i = meets the criteria from the outside
(o) to the inside (i)
i <-> o = fire side not important
AA = automatic activation
multi = multi compartment
1500 = pressure level 3 (1500Pa)
ved = vertical duct
hod = horizontal duct
vew = vertical wall penetration
V = volt
W = watt
V AC = Volt alternating current
V DC = Volt direct current
E.TELE = power supply magnet
E.ALIM = power supply motor
Auto = automatic
Tele = remote controlled
Pnom = nominal capacity
Pmax = maximum capacity
DAS MOD = modular product
OP = option (delivered with the product)
KIT = kit (delivered separately for repair or
upgrade)
PG = connection flange to the duct
GKB (type A) / GKF (type F): "GKB" stands
for standard plasterboards (type A accor-
ding to EN 520) while "GKF" plasterboards
offer a higher fire resistance for a similar
plate thickness (type F according to EN
520)
Cal-Sil = calcium silicate
ζ [-] = pressure loss coefficient
Q = air flow
∆P = static pressure drop
v = air speed in the duct
Lwa = A-weighted sound power level
ME = motorised
H = habitat
aesthetic solution
-
superior air tightness (tested at 1500 Pa)
optimal free air passage and minimal pressure loss
