Explosion-proof fans are ventilation and cooling devices specifically designed for environments containing flammable and explosive gases, vapors, or dust. Their core feature is the ability to prevent themselves (including the motor, blades, casing, switches, etc.) from becoming an ignition source, thus avoiding explosions or fires. They are primarily used in petrochemicals, pharmaceuticals, aerospace, automotive manufacturing, paint and coatings, and research laboratories.
① Complies with the national GBT 3836.1-2021 explosion-proof standard, featuring a dual-core explosion-proof system combining flameproof and intrinsically safe technologies. Key components utilize a spark-free design to ensure active safety, completely mitigating risks from the energy source and creating a safe production environment;
② Equipped with cutting-edge explosion-proof technology, certified to national IIB standards. ① T1-T6 stringent certification, the cutting-edge explosion-proof system can handle a variety of complex and high-risk gas conditions, ensuring stable and safe operation in diverse hazardous gas environments;
② The fan body and key components widely use high-strength aluminum alloy and special stainless steel materials. These materials not only possess excellent lightweight and corrosion-resistant characteristics but also effectively suppress static electricity accumulation and resist high-intensity impacts through precise structural design, eliminating potential combustion and explosion risks caused by material issues;
③ The motor and electrical cavity adopt a fully enclosed, explosion-proof dedicated structure. Even if internal sparks or explosions occur, the precise flange gap and robust casing can isolate flames and high temperatures, effectively preventing the spread of explosion energy to the outside, thus ensuring the safety of the external hazardous environment;
④ Equipped with a specially made all-copper wire explosion-proof motor, using H-class and above insulation materials, it has super overload capacity and temperature rise control technology, ensuring low temperature rise even under long-term high-load operation, fundamentally eliminating the risk of spontaneous combustion caused by motor overheating;
⑤ The fan blades are optimized and designed using aerodynamic simulation software, adopting multi-wing or backward-curved blade types. This not only achieves a perfect balance of ultra-large airflow and air pressure but also effectively reduces operating noise and energy consumption, demonstrating energy-saving and efficient professional-grade performance;
⑥ Key rotating parts use imported high-quality sealed bearings and long-lasting lubrication technology, possessing excellent dustproof, moisture-proof, and wear-resistant properties, ensuring that the fan can still achieve tens of thousands of hours of trouble-free stable operation under harsh working conditions, with durability far exceeding ordinary equipment;
⑦ The surface is treated with special electrostatic spraying or electrophoretic coating, giving it IP55 and above high-level protection capabilities, allowing it to easily cope with extreme industrial environments such as humidity, salt spray, acid and alkali, and dust, demonstrating strong environmental resistance;
⑧ Our company provides a comprehensive after-sales service network covering most areas of the country, ensuring worry-free use for users (Note: excluding a very few remote towns);
⑨ We provide multi-faceted free technical services, including video, telephone, and online video tutorials, intuitively demonstrating equipment performance and operation methods, helping users quickly master operation methods and troubleshooting.
