Axial Flow Fire Smoke Exhaust Fan HTF Series AxialFire Smoke Exhaust Fan P39

Product Features:

• High balance accuracy: Utilizes steel impellers with rigid structure meeting maximum speed requirements. Axial fan blades undergo static and dynamic balance testing, achieving residual unbalance within AMCA204 standard G2.5 balance grade.
  
• Excellent fire resistance and high temperature durability: According to GA211-2009 "Fire Smoke Exhaust Fan High Temperature Resistance Test Method," capable of continuous operation for over 30 iminutes at 280°C in typical building applications.
  
• Wide application: Suitable for smoke extraction, ventilation and exhaust in high-rise buildings, underground garages, subways, tunnels, etc.

Technical Parameters

	Shell: Surface quality of the fan box The casing of Yingda fans is made of high-quality Q235 hot-rolled carbon steel plates from Benxi Steel, which features high strength and corrosion resistance. The company is equipped with advanced laser cutters for material cutting, ensuring that the surface of the plates is free of scratches and has a bright appearance. The inner layer of the board is coated with anti-corrosion and anti-rust paint, and the outer layer is made of high-grade gray. With two layers of paint, it ensures that the equipment will not rust for a long time under outdoor working conditions.
	Motor Yingda fans are equipped with complete motor production facilities and dedicated motors for fans, all of which have passed ISO9001, high-temperature 3C fire protection certification,explosion-proof certification and energy efficiency labels. The motor should be closely matched with the fan load and adopt a B3 installation structure. The motor protection class is IP54, the insulation class is F, and the temperature rise class is B. The motor bearings should be of ball type and self-lubricating type. The motor power reserve coefficient should be taken at 110% to enhance the safety of the fan's operation.
	Impeller The blades of Yingda fans are designed through multi-objective optimization based on the principles of aerodynamics. The wheel hub is formed by stamping processing. The connection between the impeller and the blades is made by riveting or welding after positioning with a template, which has the advantages of correct installation Angle and small deviation. Each impeller has undergone static and dynamic balance tests. The impeller should undergo static and dynamic balancing to reach the G2.5 balance grade of the international standard.
	Motor junction box As the motor is located inside the fan, the supplier should provide a motor junction box that leads the wiring to the outside of the fan, and equip the correct type of junction box respectively according to the application of fire-fighting type, explosion-proof type, general type, etc.
