The speed is 1450 rpm and the power is 4 kW. For a 4 meter hood, according to the projected surface wind speed of 0.5 ~ 0.8 m/s and the width of the hood is 1 meter, the calculated air volume is approximately:
4*1* 0.5 (0.8)*3,600 = 7,200 (11,520) m3/h
In other words, the exhaust volume of the fan must be 7,500 to 12,000 m3/h.
The speed is 1450 rpm and the power is 4 kW.
The fume hood is a device installed at the fume outlet of the water heater. It is used to reduce the impact of backflow on the combustion performance of the burner, it is beneficial for the evacuation of smoke and facilitates the evacuation of smoke; combustion gas leak when the flue is blocked.
