For suction of clean and dusty air. These two-stage fans provide a high efficiency allowing to save electric power thanks to the special impellers with overturned blades. They are used to oxygenate impure waters, for pneumatic conveying, in cement factories, foundries, mills, pasta factories, dying factories (in wool rapid drying), in ceramics factories (pneumatic cleaning of work premises), in chemical, siderurgical and metallurgical industries where fans with low and medium flow rates and very high pressure are required.
