Rosenberg Launch New Energy Saving EC Centrifugal Fan: DRAG
Our supply partner,
Rosenberg, has recently launched a new EC centrifugal fan in a scroll casing.
The DRAG fan brings EC technology, energy efficiency and speed control to our range of double inlet forward curved centrifugal fans. Due to the different positions available for the mounting stand and the DRAG’s compact design, it is very versatile even in confined spaces.
Key Features – DRAG EC Centrifugal Fan
the DRAG is available in all 90° mounting positions
it uses an energy saving EC
( external rotor motor read our EC technology guide) ( that exceeds IE4 Super Premium Efficiency What is an external rotor motor?) (a standard set by the International Electrotechnical Commission) it benefits from infinitely smooth integrated speed controlling and integrated motor protection
its impeller is specifically designed for high efficiency centrifugal air movement
the high number of blades on the impeller mean that is it optimally designed to minimise noise
the DRAG motorised impeller is statically and dynamically balanced according to DIN ISO 21940-11 with quality level G2.5
the scroll casing is made from galvanised sheet metal and is fluidic optimised
maintenance free ball bearings closed on both side with long-term lubrication
ModBus RTU Interface is integrated
Protection Class IP54
( read our ingress protection guide) the DRAG is available in two sizes; 250mm and 280mm
constant pressure and constant temperature control can be achieved using a pressure / temperature sensor or controller
Typical Applications of the DRAG
Rosenberg’s double inlet centrifugal DRAG range were specifically developed for process air technology and air conditioning. It is typically applied in settings such as:
Air Handling Units
Renewable Energy Sources, e.g. Wind Turbines
What does DRAG stand for?
D = double inlet R = radial fan A = high efficiency impeller G = EC motor
