The side wall axial flow fan is a type of axial flow fan. It is named so because it is mainly installed on the side walls of buildings for ventilation and air exchange.
Edge structure features: Edge wall axial flow fans, such as suspended exhaust fans, usually adopt square or circular shell designs, which are convenient for installation on concrete walls, brick walls, or light steel profile wall panels. Their impellers are mostly forward-swept blades, and are paired with external or internal rotor fan-specific motors for direct connection transmission. The structure is compact and the operation is reliable.
Edge structure features: Edge wall axial fans are usually equipped with square or circular housing designs, which facilitate their installation on concrete walls, brick walls, or light steel profile wall panels. The impellers of these fans are mostly designed in a way that allows for easy installation. The performance parameters of the edge wall axial fans are as follows: The impeller diameter typically ranges from 220mm to 900mm, with the air volume ranging from 1500m³/h to 25000m³/h, and the air pressure ranging from 40Pa to 250Pa.
Working principle: The motor drives the impeller to rotate, causing the blades to generate rotating airflow. Under the action of the impeller, the airflow accelerates and forms a high-speed airflow that is then discharged from the fan outlet, achieving the function of ventilation and air exchange.
Product features: It has the characteristics of large air volume and low noise. The forward-swept blade design effectively reduces the separation of airflow from turbulent flow and improves the efficiency in low-pressure conditions. At the same time, the entire fan unit usually adopts a maintenance-free design. The motor directly drives the impeller without any transmission components. It is paired with permanently sealed self-lubricating ball bearings, which reduces maintenance costs.
The suspended exhaust fan with side wall axial flow is widely used in factory and enterprise workshops, as well as in civil and commercial construction projects for side wall ventilation and air exchange. Additionally, according to customer requirements, explosion-proof fans can be manufactured, which are used in places with flammable and explosive gases.
Optional accessories: Usually, a 45° rainproof cover and insect-proof net are routinely equipped. It can also be equipped with a 90° rainproof cover and insect-proof net. A gravity-type check valve can also be selected to isolate the internal and external air when the fan is not running.
