Detailed Description
Features and Applications
The design of the HTF axial flow smoke exhaust fan is unique, with a fully enclosed high-temperature motor built-in and equipped with a dedicated motor cooling system. The axial flow and mixed flow impeller structures are optimized using CAD software with multiple objectives. Through a multi speed drive form, it achieves dual use of one machine (i.e. commonly used for supply and exhaust ventilation and high-temperature smoke exhaust for fire protection). After being equipped with an electric control box, it can be remotely automatically controlled. It has the advantages of excellent high-temperature resistance, high efficiency, small size, and easy installation (horizontal, vertical, and lifting can be used), and is widely used in high-rise buildings, drying rooms, underground garages, subways, tunnels and other occasions for fire smoke exhaust and supply ventilation. According to the standard clause 4.4.3.7 of GA211-2009 "High temperature resistance test method for fire exhaust fans", it can operate continuously for more than 30 minutes without any abnormalities under high temperature conditions of 20 ℃, and has been recognized and adopted by fire departments in major cities across the country. The relevant products have passed the mandatory 3C certification of the country.
