Products; fire exhaust fan installed in the production of it can be directly connected to the wind pipe or wall mounting roof exhaust fan, and it can be installed in the form of vertical or horizontal, so it saves a large extent covers area. In addition, it also can be run continuously at 300 ℃ high temperature for 60 minutes or more, under 100 ℃ temperature conditions for 20 hours / time is not damaged, it is widely used in high-level civil, oven, underground garages, tunnels and other occasions. Exhaust fan fire wide range of applications: it can be based on different requirements of senior civil construction, the use of variable speed drives in the form of multi-speed exhaust fan the fire, in order to achieve one machine (ie, when used through ventilation and fire temperature exhaust) purpose; leaf type into Axial (HTF-Ⅰ, Ⅱ) and mixed flow (HTF-Ⅲ, Ⅳ), so fans of the series has a wide range of performance parameters. Require special attention to the noise when users are higher, can be made into a silencer-type fan. 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. Accident tunnel ventilation system to supply air from the direction of a secure tunnel to cross the channel by inhibiting the flue gas into a cross-channel and the accident did not occur in the tunnel exhaust fan, meet new evacuees facing into the wind tunnel cross passages and safety, while ensuring that waiting area needed fresh air in the tunnel area in accordance with the different 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 settings can be contacted reversing fan made from fresh wind tunnel safety temperature exhaust fan fire |.
