Francis HTF temperature exhaust fan is a series of products, the performance of the new fan between axial and centrifugal fans between the inlet manifold is equipped with silencer, the outlet is equipped with baffles, and is designed to carry a secondary gas, help to reduce the ambient temperature of the motor. Francis temperature exhaust fan with high efficiency, energy saving, low noise, compact, light weight, small size, reliable operation, easy installation htf exhaust fan manufacturers, exhaust fan can run one hour at 300 ℃ environment, both for ventilation can play the role of fire temperature exhaust. Temperature exhaust Francis fan Uses: used in senior civil and underground warehouses, ovens, tunnel and mining enterprises and other sectors of ventilation and fire smoke. 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 both ends of the inclined shaft and tunnel exhaust fan fire rescue station designated as the wind and smoke into new channels, cross ventilation openings must maintain positive pressure state htf-i fire exhaust fan, prevent the flue gas flow channel. ventilation system blowing from the direction of the accident tunnel through a secure tunnel to cross the channel, inhibiting the flue gas into a cross-channel and the accident did not occur in the tunnel roof exhaust fan fire, meet evacuees facing the new air into the transverse channel and within a secure tunnel, waiting area while ensuring the required fresh air tunnel according to different regions use different incidents of disaster prevention and Ventilation. "sentinel" Disaster ventilation scheme implemented sentinel relief when the train, in the "fixed" range all cross-channel contact settings can be reversed to obtain fresh wind from the fan inside the secure tunnel roof exhaust fan, exhaust fan Pingdingshan, Chen Yu-conditioning services provided by Wu Cheng Chen Yu Air Conditioning Equipment Co..
