High-Efficiency Centrifugal Roof Exhaust Fan: Powerful Ventilation Solution

Our high-efficiency centrifugal roof exhaust fan is designed with an upper exhaust design with a backward centrifugal aluminium impeller. The fan’s circular arc venturi tube ensures smooth airflow, and the impeller is meticulously balanced to meet international standards (ISO 1940G2.5). The robust aluminium alloy construction of both the fan casing and impeller provides exceptional durability and resistance to corrosion.
The fan’s motor is carefully matched to its load, offering reliable performance and energy efficiency. The motor is strategically placed outside the airflow to prevent dust and grease buildup, ensuring long-lasting operation. The motor is rated IP44 for protection against water and solid objects, and it has a B insulation class and ball bearings for added durability.
The fan cover and outer housing are made of thick aluminium plating, providing superior strength and protection against harsh weather conditions. The design prevents water leakage, even in heavy rain or snow. The drive mechanism support plate is made of galvanised steel for corrosion resistance and structural support, ensuring the smooth operation of the drive components without excessive vibration.
The flashing and air inlet are integrated to prevent water seepage, and the flashing has mounting holes for secure attachment to the roof flashing structure. A sturdy anti-bird grill made of cold-drawn iron wire protects the fan outlet from obstructions.

Fan Performance and Testing
The fan’s performance parameters are tested in accordance with Air Movement and Control Association Standards 210 and 310. These tests are conducted on the entire fan to ensure accurate performance data.

Applications:
Our belt-driven centrifugal roof exhaust fan is ideally suited for installation on the roofs of industrial and mining plants, civil buildings, shopping malls, and other venues where efficient air extraction and exhaust are required.
