One. HTF (GYF) series exhaust fan fire overview of the characteristics of (1) HTF (GYF) series fire temperature exhaust axial fans, with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation Features. (2) HTF (GYF) series axial fan the fire temperature exhaust fan sold in Beijing, Tianjin, Shanghai classics, Chongqing, Zhejiang, Guangdong, Jiangsu htf-i exhaust fan fire, Shandong, Henan, Hebei, Anhui, two-speed Fire exhaust fan, Hunan, Sichuan, Liaoning, Hubei, Shaanxi, Jilin, Inner Mongolia, Shanxi, Guizhou, Heilongjiang, Fujian, Jiangxi, Yunnan, Shenzhen and other provinces (municipalities) and autonomous regions. (3) high-temperature performance: Fan tested to meet fire code standards GBJ45-82 fan with a unique design, high temperature motor built-in, configure the motor cooling system can operate continuously at 300 degree camera's high temperature above 100 minutes, 100 Photo's degree under the temperature conditions for 20 hours / times without damage, are widely used in high-level civil, oven, underground garages, tunnels and other occasions; fire exhaust fan set Location: exhaust fan fire away from the tunnel side walls should not be too close exhaust fan, so as not to affect the ventilation. fire exhaust fan arrangement minimum distance from the tunnel wall is 20 cm, rescue "sentinel" setting the tunnel is divided into different regions of disaster prevention, full use of the rescue station at the point deviated and two tunnels As the end of the exhaust fan fire into the fresh air and exhaust channels, cross ventilation openings must maintain positive pressure state roof exhaust fan fire, prevent the flue gas flow channel. ventilation system from a secure tunnel to tunnel through the cross channel to the accident the direction of air, flue gas into a cross-channel and suppress tunnel accident did not occur to meet the evacuees facing the new cross-channel air into the tunnel and security, while ensuring that the required waiting area with fresh air. According to different regions using the tunnel accident Disaster different ventilation mode. "sentinel" Disaster ventilation scheme implemented sentinel relief when the train set can be reversed in the "sentinel" range for all of the cross-channel fan made contact with fresh air from within the security tunnel. fire smoke Fan, Chen Yu-conditioning (certified), exhaust fan Zhoukou City by Wu Chen Yu Air Conditioning Equipment Co., Ltd.
