Outer casing (A)
Casing in hot galvanized sheet metal with plastic ex-
ternal coating.
It can be easily disassembled for complete accessi-
bility of the unit.
The air discharge grid, which is part of the casing, is
adjustable and positioned on top.
Fan assembly (B)
Consists of a particularly quiet tangential fan. The
aluminium fan blades are statically and dynamically
balanced and are fixed directly to the motor shaft.
Electronic motor (C)
The motor is installed on the right side of the unit,
is a three phase permanent magnet DC brushless
electronic motor, with low energy consumption,
electronically driven and controlled with current
reconstructed according to a BLAC sinusoidal wave.
The inverter board that controls the motor opera-
tion is powered by 230 Volt, single-phase and, with
a switching system, it generates a three-phase fre-
quency modulated, wave form power supply.
The electric power supply required for the machine
is therefore single-phase with voltage of 230 V and
frequency of 50-60 Hz.
