Temperature exhaust fan blade surface treatment prevents wear under normal circumstances a large exhaust fan, we learned of the blade surface temperature exhaust fan can carburizing, plasma welding, spraying carbide, ceramics and paste process. Common advantage of these methods is to increase the hardness of the top exhaust fan blade surface, which to some extent, improve the wear resistance of the blade, but a variety of methods have their disadvantages. HTF (A) -W series roof exhaust fan with molded axial flow impeller, built high temperature motor (arrangement specialized motor cooling systems), rain hood, the base pan of water. High temperature performance, high efficiency, small size, easy installation, and other advantages. High temperature: The fan is designed with special motor cooling system. Main air duct medium temperature of 280 ℃, it can be more than 30 minutes of continuous operation. 150 ℃ when long-term continuous operation. Small size and lightweight light: the amount of wind centrifugal fan with less accounted for two-thirds of the space. Lighter than half. Simple structure: The fan can use vertical and horizontal hanging installation according to the requirements of building construction. Power three-phase 380V, 50HZ. Temperature exhaust fan, air conditioning Shenglong (certified), Tangshan exhaust fan ventilation and air conditioning provided by the Texas Shenglong plant. Texas Shenglong ventilation and air conditioning plant (www.fengguan666.com) (www.dzsltfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
