MOTOR FAN GROUP
Single-inlet centrifugal fan with statically and dynamically balanced plastic
impeller. The 3-speed electric motor, made to international standards,
has an overload cut-out and the run capacitor always connected. The
motor is directly coupled to the fan and cushioned with flexible mountings.
It is particularly efficient
and low noise.
DÉCOR PANEL
The décor panel has an innovative design so that the appliance may
be used in both dwellings and business premises. The white (RAL 9003)
panel is made in lightweight but strong plastic. Fixing to the load-bearing
structure is quick and easy. 4 adjustable louvers ensure best air
distribution throughout the room. Central intake grille with filter for
cleaning the air. The grille may be removed to access internal parts
without having to remove the panel from the ceiling.
ELIMINATION OF CONDENSATION
Condensate collecting system comprising:
- internal plastic tray for collecting condensation coming from the heat
exchanger;
- external auxiliary plastic tray for collecting condensation coming from
the valves and connecting pipes.
Electric pump, which is an integral part of the appliance and connected
to the external fitting.
