Noise levels are kept remarkably low at 35 dB(A), thus the fan’s operation won’t disrupt daily activities.   

The fan incorporates critical safety measures such as an IPX4 outdoor protection rating and a 145°C thermal fuse to enhance durability and prevent overheating. 

With dimensions of 250 × 250 × 163 mm and a cut-out size of 200 × 200 mm, the fan fits neatly into standard wall openings. Its 1.4-kg weight helps ease the installation. Rang Dong recommends this model for rooms with a volume of 22.5 m³, or a size approximately of 3 × 3 × 2.5 meters, to achieve optimal ventilation performance. 

Exceptional Features 

One of the strongest advantages of this wall-mounted exhaust fan lies in its aerodynamic engineering.  

The fan blades and motor are researched, designed, and simulated with precision to deliver stable performance over long periods. The optimized structure keeps the airflow consistent at 270 m³/hour, enabling rapid removal of moisture, heat and unpleasant odors from confined areas. 

The fan’s high airflow capacity enhances indoor comfort and contributes to improved air quality by expelling pollutants and excess humidity. Hence, it helps create a fresher environment that supports respiratory well-being and reduces the risk of mold growth, an important factor for modern homes to consider. 

Operating at an ultra-quiet 35 dB(A), model QHGT01.1C provides smooth, comfortable ventilation without disturbing surrounding spaces. 

Another standout feature is the fan’s extremely quiet operation. Thanks to the optimized blade design and the use of high-quality ball bearings, the fan produces minimal noise even during extended use. The feature makes it suitable for spaces where noise control is important, such as bedrooms, office areas and study rooms. 

Durability is also a key advantage. The robust motor design and protective sealing contribute to a long service life, even in humidity-prone environments such as kitchens and bathrooms.   

The fan maintains stable operation while requiring minimal maintenance, reflecting Rang Dong’s commitment to reliability and product longevity. 

Applications 

Model QHGT01.1C is suitable for a wide range of everyday applications.  

In kitchens, the fan efficiently removes cooking fumes, steam and lingering odors, helping maintain a pleasant atmosphere. In bathrooms and restrooms, it quickly eliminates humidity, preventing condensation and supporting hygiene. 

Rang Dong’s wall-mounted exhaust fan delivers a strong airflow, effectively removing humidity and odors. 

Besides, the fan is ideal for laundry rooms, storage spaces and utility areas where moisture and stale air commonly accumulate. For small offices or enclosed workspaces, it contributes to improved ventilation, which provides better comfort and productivity.  

Thanks to its quiet operation and compact structure, the wall-mounted exhaust fan can also be installed in bedrooms or study areas, where maintaining a calm and well-ventilated environment is essential.  

Overall, Rang Dong’s model QHGT01.1C provides flexible and practical ventilation solutions for both residential and commercial settings.
