Backward-curved belt driven double inlet box fan

Belt driven double inlet box fans built in compliance with the ATEX Directive 2014/34/EU and suitable for environments where the presence of flammable gases makes it necessary to ensure correct air extraction avoiding the risk of explosion, in particular in ATEX certified systems in category 3, zone 2, (3G). They are suitable in installations where air replacement or filtration must be carried out and for installations that require high performance in terms of flow rates and especially pressures. Particularly quiet, they are ideal in both civil and industrial environments where noise is an issue. Suitable for clean air with temperatures from -20°C to + 40°C-
