EC Duct Fan KHAG(S)
With the new KHAG(S) EC duct fan series, Rosenberg has set a new benchmark in terms of performance, energy efficiency and acoustics. The further development of the duct fan series combines flow optimisation with an innovative sound insulation concept and a practical range of models.

Convincing even without making a big fuss
Optimised power density
The air flow rate has been significantly increased thanks to the further development of the motor impellers and the aerodynamic adaptation of the housing. Compared to the previous generation, the new models achieve a significantly higher delivery rate, depending on the type.
Important: Due to this increase in performance, the nominal data regarding power consumption and noise level change. A precise operating point design is therefore essential and can be easily carried out in the RoVent10 selection programme.
Improved sound insulation
For duct dimensions up to 700 x 400 mm, four-sided insulation has been implemented. This significantly reduces the heat radiation from the housing.
Noteworthy: even the standard version achieves a sound level that is comparable to or, in some cases, better than the soundproofed versions of the previous generation. This makes the new KHAG(S) fans certainly among the quietest duct fans in their class on the market.

Application example: Efficient ventilation solution in office buildings
A typical application for the new KHAG(S) EC duct fans is the controlled ventilation of office buildings.
Acoustic performance plays a crucial role, especially in open-plan offices: large volumes of air must be conveyed without the noise affecting working comfort. Thanks to four-sided sound insulation and optimised impellers, the new KHAG(S) fans deliver high air performance with minimal housing radiation.
In addition, the energy-efficient design ensures that operating costs remain low – an important factor for both operators and facility management companies.
