Wall mounting is the most common installation method for axial flow fans, widely applicable to scenarios requiring wall ventilation such as factories, warehouses, and basements. Before construction, standard installation holes must be pre-drilled in the wall according to the fan's outer frame dimensions. The edges of the holes must be flat and regular to avoid unevenness affecting the fit. During installation, the entire fan is embedded into the wall hole, ensuring the fan body is perpendicular and horizontally centered to the wall surface, without any tilting or offset. Then, the four corners of the fan body are secured using the matching expansion bolts. Gaps are filled and sealed with sealant or insulation cotton to prevent air leakage and reduce vibration and noise during operation, ensuring ventilation efficiency.
Dual-channel installation is mainly suitable for various ventilation duct systems and is often used for equipment exhaust, duct supply, and ventilation in confined spaces. This installation method requires a precise match between the fan and the ventilation duct diameter. Before installation, check the flatness of the duct joints and clean out internal debris and dust to prevent foreign objects from entering the fan impeller during operation. During installation, the fan is tightly connected to the pipeline at both ends via flanges. All fixing bolts are tightened evenly to prevent localized loosening that could lead to air leakage and vibration. To reduce operating noise and pipeline resonance, flexible connection damping components can be installed at the fan-pipeline connection point, while ensuring the pipeline remains straight without bending or deformation.
Floor-mounted installation is suitable for large-scale, high-volume axial flow fans, commonly used in large-area workshop ventilation, machine room cooling, and site air exchange. Before installation, the ground must be leveled to ensure the foundation is flat, solid, and has sufficient load-bearing capacity for equipment operation. Soft ground requires pre-hardening and reinforcement. After placing the fan stably in the designated position, adjust the unit's level to ensure even stress distribution and prevent tilting or swaying. Then, secure the unit with anchor bolts. In some cases, a vibration-damping base can be added to effectively buffer vibrations generated during fan operation, preventing equipment displacement, component wear, and improving operational stability.
Ceiling-mounted installations are commonly used in concealed ventilation scenarios such as shopping malls, offices, and computer rooms, saving floor space and maintaining a clean and aesthetically pleasing environment. This installation method relies on the building's ceiling joist structure, requiring prior confirmation of the ceiling's load-bearing capacity to ensure it can support the entire weight of the fan and prevent the risk of it falling off. During construction, first fix the dedicated hoisting rods, accurately calibrating the rod spacing and levelness, then suspend and secure the fan, tightening all hoisting fasteners. After the fan is installed, connect it to the ventilation outlet, while reserving maintenance space for future equipment cleaning, bearing maintenance, and troubleshooting. After installation, a trial run is necessary to ensure there are no issues such as shaking, abnormal noise, or air leakage before putting it into use.
