The DVG/F smoke extract fans are
used in case of fi re to extract smoke
gases from rooms, and also during
normal working conditions for stan-
dard ventilation. Smoke-free escape
ways increase the chances to rescue
people in case of a fi re. Extraction
of hot gases reduces damage on
building and equipment. The casing
is manufactured from seawater
resistant aluminium. The base frame
consists of pre-galvanised steel. The
fan has a backward-curved radial
impeller made of steel sheet. Motor
outside air stream is air cooled. The
fan is equipped with IEC motors in
IE2 effi ciency (single speed with
exception 8-pole) respectively IE1
effi ciency (two speed motors), with
protection class IP 55, insulation
class F. Thermal motor protection
PTC serially built-in. For two speed
fans (up to 4 kW) two speed switch,
S-DT2 GKT resp. DKT is available
as accessory (in this case thermal
contact must be ordered; not suitable
for PTC). In case of fi re two speed
switch and motor protective devices
must be bridged to guarantee func-
tional capability (connection direct
to mains). For speed control use only
combination of frequency converter
and appropriate all pole sine fi lter
(hot tested at LGAI with converter
and sine fi lter). If frequency conver-
ter is used in case of fi re, PTC must
be bridged and switching on max.
speed even after eventual short sup-
ply cut off assured. Operating over
50 Hz is not allowed. 60 Hz units on
request. Frequency controlled units
may need additional EMC protection
(available on request).
