i-HWD2 102 - 902
The new high head ducted units i-HWD2, are equipped with a new generation EC Brush-less motor fan with continuous modulation of the air flow, which ensures the best comfort and real energy savings. The possibility of vertical and/or horizontal installation, the small dimensions and the wide range of accessories for the canalization, make these units very flexible in installation and adaptable to any type of system. Thanks to the brush-less motor and the internal insulation, i-HWD2 guarantees operation with high levels of acoustic comfort.
