The fan uses a special compartment temperature measures, built on the motor cycle can impeller axial-flow exhaust fan forced cooling, make sure the motor temperature does not exceed the specified value. To operate at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Can play the role of ventilation and fire smoke. The product was identified as sentinel Shandong Province Fire Department fire products production. YTPY type, fire temperature exhaust fan with high efficiency, smooth running, low noise, high temperature and reasonable structure, easy to install, can be vertical, horizontal and hanging installation. The fan design has a special built-in motor cooling system air-cooled motor types; uses an advanced aerodynamic design of blades (forward-swept, forward), the noise 2. Low 8-10dB (A) 6% lower power than existing fire fans ; main duct medium temperature of 280 ℃ when more than 30 minutes of continuous operation, 150 ℃ when the long-term continuous operation. Product Attributes The fan uses a special compartment temperature measures, built on the motor cycle impeller can force the two-speed exhaust fan to cool, make sure the motor temperature does not exceed the specified value. Able to run more than 100 minutes exhaust fan at 400 ℃, long-term operation at 100 ℃. Ventilation and fire smoke can play the role of the product is divided into: ① ② atmospheric pressure single-speed two-speed ③ ④ MV MV single-speed two-speed four series. Fire exhaust fan set Location: Distance tunnel fire exhaust fan should not be too close to the side wall, so as not to affect the ventilation exhaust fan fire tunnel wall arranged for a minimum distance from 20 cm, rescue "sentinel" setting will tunnel into. Disaster different regions, make full use of deviated and both ends of the tunnel exhaust fan fire rescue station designated as the wind and smoke into the new channel, cross ventilation openings must maintain positive pressure state, to prevent flue gas flow channel. air from the ventilation system to a secure tunnel through the cross-channel tunnel accident direction to fire special exhaust fan, inhibit the flue gas into a cross-channel and tunnel accident did not occur to meet the evacuees facing fresh air into the tunnel cross passages and safety, while ensuring that When the waiting area needed fresh air. According to different regions within the tunnel accident Disaster different ventilation mode. "sentinel" Disaster ventilation scheme implemented when the train rescue point in the "sentinel" range for all of the cross-channel contact Settings can be inverted to obtain a fresh wind from the fan inside the secure tunnel. htfc exhaust fan exhaust fan _ _ Jinnan District Chenyu air conditioning services provided by Wu Cheng Chen Yu Air Conditioning Equipment Co..
