"Foshan Berio Electromechanical Equipment Co., Ltd. (KAKU South China Branch) is a subsidiary established by Taiwan KAKU in Mainland China's South China region, 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 certified with IP55? 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 not 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效果. b. Fully enclosed terminal cover design of KAKU axial fans: This design prevents water and dust from entering the fan interior, avoiding short circuits caused by water intrusion into the circuit. c. Fully enclosed design of the built-in lead area: The fully enclosed lead 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, whereas traditional stators (silicon steel sheets) have partially exposed areas, which easily allow dust intrusion and basically offer no waterproof protection. Therefore, KAKU axial fans are the only fans in China certified by the SGS testing機(jī)構(gòu) with an IP55 rating, making them more suitable for humid and dusty environments. Their dustproof 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 Website: http://www.berio.com.cn Phone: 0757-22119679 "
