Rosenberg EC-Unobox

Rosenberg EC-Unobox ventilation boxes are flexible compact fans designed for small and medium air flows. The Rosenberg EC-Unobox fan housings consist of two chambers made of aluminum profiles and sandwich panels made of galvanized sheet steel. The housing of the Rosenberg EC-Unobox ventilation boxes is soundproofed and thermally insulated with 20 mm non-combustible mineral wool. The direction of the air flow can be changed at any time by replacing the panels. This flexibility allows maximum adaptation to demanding construction conditions.

Rosenberg EC-Unobox ventilation boxes up to a diameter of 450 mm have plastic impellers with backward-curved blades and side walls made of galvanized sheet steel. Rosenberg EC-Unobox fans from a diameter of 500 mm have highly efficient impellers with backward-curved blades made of aluminum. Rosenberg EC-Unobox radial fans are driven by an external rotor motor housed inside the radial impeller. The motors of Rosenberg EC-Unobox radial fans are equipped with a terminal box with IP54 protection.

The housing of the Rosenberg EC-Unobox fans consists of a frame made of hollow double-chamber aluminum profiles with plastic corner pieces and sandwich panels made of galvanized sheet steel with 20 mm thick noise and heat insulation made of non-combustible mineral wool.
