HTF (A) fire temperature exhaust axial fans characteristics and application HTF (A) fire temperature exhaust axial fan using advanced CAD-aided design system, is the more optimized design of new products developed roof exhaust fan, has High efficiency flat curve characteristics conducive to energy conservation. Optional molded axial flow impeller, built-in high-temperature motors, arranged a special motor cooling system. Selection of two-speed direct-drive motor, to one machine (ie usually send row when using high-temperature exhaust ventilation and fire), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, high efficiency, small size, easy installation (horizontal, vertical, lifting may be), etc., are widely used in high-rise buildings, drying room, underground garages, subways, tunnels and other occasions to send fire smoke and exhaust ventilation . Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ high temperature continuous 100 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, has been approved for use by fire departments in major cities nationwide. Fans of the series can be installed in accordance with the requirements of occasions, peripherals silencer box, made HTF (A) -X box-shaped exhaust fan fire. Fire exhaust fan set Location: Distance tunnel fire exhaust fan should not be too close to the side wall exhaust fan fire htf avoid affecting ventilation exhaust fan fire tunnel wall arranged for a minimum distance from 20 cm exhaust fan, rescue. " sentinel "setting will tunnel into different regions Disaster kitchen exhaust fan, exhaust fan fire full advantage of both ends of the inclined shaft and tunnel rescue station designated as the wind and smoke into new channels, cross ventilation openings must be maintained in a positive state, to prevent 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 tunnel accident did not occur to meet the 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 turbines within a secure tunnel from the kitchen exhaust fan |.
