The principle of ventilation and cooling of sanhe exhaust fan
The technology derived from Europe, standard and manufacturing process is wholly in accordance
with the European CAD/CAM. Exhaust fan is installed in one side and evaporative cooling pad is
Installed in the other side, then heat and exhaust inside will be taken away because of negative
Pressure and fresh and filtered air will be pumped into through pad to make the air cool down
by natural physical phenomenon----evaporation.
The combination of exhaust fan and evaporative cooling pad can sustain the factory temperature
in less than 30 and make the factory air change 80--90times per hour, no matter how high
the original temperature is.
The combination of exhaust fan and evaporative cooling pad:
1) sanhe 1380 exhaust fan with 6 square meter of evaporative cooling pad can meet 500 --550m³.
2)sanhe1220 exhaust fan with 5 square meter of evaporative cooling pad can meet 450--500m³.
3)sanhe1100 exhaust fan with 4 square meter of evaporative cooling pad can meet 400--450m³.
4)sanhe900 exhaust fan with 3 square meter of evaporative cooling pad can meet 350--400m³.
application:
Our exhaust fan can be used in almost all places which need ventilation and cooling.
