Rosenberg ER / DR
Highly efficient Rosenberg ER (230V) / DR (400V) axial fans for circular ventilation ducts are used wherever large volumes of air need to be transported at low to medium pressure. Rosenberg ER / DR axial fans have a housing made of electrostatically painted galvanized sheet steel.
Rosenberg ER / DR industrial axial fans are designed for use in air conditioning or ventilation applications. Rosenberg ER / DR wall-mounted fans are used to transport air in various types of systems, either for ventilation, cooling or exhaust, e.g. for ventilating restaurants, gyms, conference rooms, workshops, warehouses or greenhouses.
Housing
Rosenberg ER (230V) / DR (400V) industrial exhaust fans have a housing made of painted galvanized sheet steel.
Impeller
Highly efficient axial fans have aerodynamically profiled blades - from size 200 mm to 300 mm they are made of galvanized sheet steel - size 350-4.4EC made of painted steel, sizes 315 mm to 630-6 are made of plastic, sizes 630-4 to 1000 mm are cast from aluminum.
Electrical connection
The electrical connection of axial fans is made using a terminal block with IP44 protection, which is included.
