Foshan Belio Electromechanical Equipment Co., Ltd. (KAKU South China Branch) is a subsidiary established by Taiwan KAKU in Mainland China's South China region. It is responsible for the sales of KAKU's existing products and the promotion and trial marketing of new KAKU products in the South China market. There are many counterfeit KAKU products on the market. To protect your customers' interests, please choose genuine KAKU products. Why is the KAKU (KA2072HA2B) axial fan the only fan in China that has passed IP55 certification? The first "5" in IP55 represents the dust protection level, and the second "5" represents the waterproof level. The higher the number, the higher the protection level. Other brands of fans on the market have never undergone IP rating tests. Their dust protection can only reach level 3, and they have no waterproof function, so they can only be labeled as IP3X. KAKU fans adopt the following special treatments to achieve waterproof and dustproof effects: a. Special design for surface heat dissipation: The bottom side of the KAKU fan frame features a finned凹凸 design to increase the heat dissipation area. Additionally, magnesium alloy fan blades are used to enhance heat dissipation efficiency. b. Fully enclosed terminal cover design: This design prevents water and dust from entering the fan interior, avoiding short circuits caused by water intrusion into the circuit. c. Fully enclosed built-in wiring area design: The fully enclosed wiring area effectively prevents the intrusion of water and dust. d. Fully enclosed design at the junction of the KAKU fan blade and stator: The unilateral gap is ≤0.3mm. In contrast, traditional stators (silicon steel sheets) are partially exposed, making them prone to dust intrusion and offering basically no waterproof protection. Therefore, the KAKU axial fan is the only fan in China certified by the SGS testing機構(gòu) as IP55. It is more suitable for humid and dusty environments, and its dust and waterproof parameters fully meet the IP55 protection等級 standard. Commonly used KAKU axial fan models include: KA1238HA2B, KA1725HA2B, KA1505HA2B, KA1606HA2B, KA1806HA2B, KA2206HA2B, KA2208HA2B, KA2072HA2B, KA2509HA2B.
