Rosenberg Zero Box - noise-insulated duct fans
Rosenberg Zero Box sound-insulated duct fans were developed specifically for use in modern ventilation and air conditioning systems and are suitable for moving air containing low levels of dust and mildly corrosive gases and vapors. The housing of the Rosenberg Zero Box duct fans is made of galvanized steel sheet. The housing is sound-insulated with 40 mm thick mineral wool panels.
Impellers
The Rosenberg Zero Box duct fans are driven by an EC or AC motor with an external rotor located inside the radial impeller. Fans up to size 250 mm have impellers with forward-curved blades; from size 315 mm, impellers with backward-curved blades are used.
Electrical connection
The electrical connection is made via a terminal block located on the fan housing.
Installation
Circular HVAC ducting, flexible aluminum ducting, or plastic ducting can be used for connection. Installation is possible in all positions.
