Fans
Fans are not included in the basic package. For the
best results, one fan per extraction unit is recom-
mended. It is also possible to connect several units
to a central fan.
To get underpressure in the ducting system and avoid
exhaust leakage, the fan should be positioned as near
the duct outlet from the room as possible.
Alternative connection for fan.
(picture 11a, 11b, 11c))
Automatic disconnection (picture 12)
Extraction units delivered with automatic disconnec-
tion have a factory adjusted wire connected to trolley,
safety coupling and nozzle.
The disconnection trigger must be fitted to the rail
according to the figures. The dimension X must be
minimum 1,0 m, but adjusting to required position
for disconnection must be made at the place of
installation.
