HTF fire high temperature exhaust axial fan

HTF fire axial flow fan is usually equipped with double speed motor, in normal time, the motor runs at low speed for ventilation, once fire happens, the motor will be changed for high speed operating automatically through electric control system and remove the smoke rapidly within half an hour.

A HTF Type Fire High Temperature Exhaust Axial Flow Fan

Summary of 1.HTF type fire high temperature exhaust axial flow fan 1.1.HTF type fire high temperature exhaust axial flow fan, Its basic form is axial flow structure, High temperature resistant motor, Equipped with a special motor cooling system, According to the GA211-2009< test method of high temperature resistance of fire exhaust fan, For more than 60 minutes ℃ continuous operation at a medium temperature of 300, 100℃ Continuous operation for 20 hours/times at temperature without damage, Ventilation and smoke exhaust can be used. 1.2. Classification of products by installation: horizontal and roof type (W type). :: Air pressure according to air volume: atmospheric pressure type 1, II type (double speed); medium pressure type (impeller is inclined flow type) has II,IV type (double speed); Low pressure type has D1,D: type. :: Single speed, double speed, frequency conversion (using frequency conversion motor, Frequency controller, Frequency conversion, To suit different conditions, The adjustment frequency is recommended to be locked at 25 Hz~50 Hz). 1.3. To meet the noise requirements of different locations, Fan can be equipped with different length muffler, Can also be made into a coating type. 2.HTF Working Conditions of Axial Flow Fan with High Temperature and Exhaust Smoke

Working temperature :-20~+60℃(continuous operation); High temperature resistance :100℃(20 hours continuous operation), 300℃(60 minutes of continuous operation); Wet medium conditions: air (dust content not exceeding 100 mg/㎡); Working Power: Three-phase ,380 V/50Hz.:<90 per cent;

Application of 3.HTF Fire High Temperature Exhaust Axial Flow Fan

Fan can be widely used in high-rise buildings, oven, underground garage, tunnel and other ventilation and exhaust places.
