Based on their installation structure, axial flow fans are mainly divided into several common types: wall-mounted, duct-mounted, floor-standing, and ceiling-mounted, adapting to the ventilation needs of different sites. Wall-mounted axial flow fans have a simple structure and a thin body, primarily embedded in wall openings, and are often used for direct exhaust ventilation in workshops and warehouses. They are easy to install and do not occupy indoor space. Duct-mounted axial flow fans are compatible with ventilation duct systems, allowing for axial air delivery via ductwork. They offer concentrated airflow and low resistance, suitable for systematic ventilation scenarios such as ducted air supply and equipment exhaust. Floor-standing fans have a stable base and a larger airflow, suitable for open-plan ventilation and cooling in large factories. Ceiling-mounted fans are concealed within the ceiling, offering a clean appearance, and are often used in office buildings, computer rooms, and other indoor ventilation scenarios where aesthetics are important.
Based on materials and corrosion resistance, axial flow fans can be divided into three categories: ordinary carbon steel, stainless steel, and fiberglass corrosion-resistant. Ordinary carbon steel fans, after being painted for rust prevention, are low-cost and structurally robust, suitable for ventilation environments in dry, non-corrosive conventional factories, and are commonly used in civil and general industrial projects. Stainless steel axial flow fans offer superior rust and moisture resistance, excellent weather resistance, and are suitable for high-humidity environments such as basements, aquatic product workshops, and damp processing workshops, and are not prone to rust or damage during long-term operation. Fiberglass anti-corrosion fans possess extremely strong acid and alkali resistance and corrosion resistance, specifically designed for harsh working conditions involving corrosive waste gases, such as chemical, electroplating, and pickling processes. They effectively resist corrosive media erosion, and their durability far exceeds that of ordinary metal fans.
Based on their function and explosion-proof characteristics, axial flow fans include two core models: ordinary and explosion-proof. Ordinary axial flow fans have a simple structure and stable operation, suitable only for conventional ventilation scenarios without flammable or explosive gases, meeting daily ventilation, heat dissipation, and dust removal needs. Explosion-proof axial flow fans have undergone explosion-proof structural modifications. The motor, impeller, and body accessories are all designed to be explosion-proof. They will not generate sparks during operation, effectively eliminating the risk of ignition and explosion. They are specially designed for use in high-risk locations such as oil and gas workshops, chemical warehouses, and spray painting workshops where there are flammable gases and dust. They are dedicated ventilation equipment to ensure the safety of ventilation operations in flammable and explosive conditions.
