Performance Parameters: When selecting a fan, pay attention to core indicators such as air volume (m³/h), air pressure (Pa), power (kW), and noise (dB). For example, a chemical workshop needing to remove corrosive gases requires an explosion-proof axial flow fan with an air volume of 8000 m³/h, an air pressure of 300 Pa, and a power of 2.2 kW.
Material Requirements: Select materials based on the operating environment. For example, in coastal areas, 316L stainless steel is required to resist salt spray corrosion; in high-temperature environments, high-temperature resistant motors (such as H-class insulation) are necessary.
Safety Certification: For explosion-proof scenarios, confirm whether the fan has passed international certifications such as ATEX and IECEx, and the protection level must reach IP65 or higher.
Maintenance Convenience: Prioritize products with access doors and flange connections for easy cleaning and component replacement. For example, a power plant selected a fan with a hinged access door and a flange outer diameter of 560 mm, reducing a single maintenance time to 30 minutes.
