• Frame in extruded aluminium profi le; removable panels in galvanized steel sheet; all this brings to an excellent aesthetic impact. Weatherproof cover in galvanized steel sheet.
• The blower is fi tted using suitable support feet and is completely isolated from the casing by anti-vibration mounts and gaskets.
• Acoustic lining in self-extinguishing technopolymer.
• Double inlet blower, forward curved, with direct drive built-in asynchronous motor, singlephase or three-phase, IP20, class F, particularly suitable for speed regulation (using the suitable speed regulators shown in this catalogue).

The fans of the BOX-D series are particularly designed for air extraction, supply or fi ltration. Their main characteristic is the low noise level which makes them ideal for urban environments (apartments, houses, bar, restaurants, gymnasiums, offi ces) and industrial sites where
the noise is a problem. The low noise level is due to their plenum lined with acoustic material, that allows a remarkable reduction of noise level, inevitably generated by the fan. The blower consists of a double inlet forward curved centrifugal fan with built-in motor.
