Wall-mounted fresh air does not need a suspended ceiling, just make a hole in the wall.
In addition to the matching of air volume, the pressure of the fan should be greater than the pressure formed by the pipe and the tee elbow, and the purifier should be determined according to the fan and smoke exhaust volume. >>>More
In fact, I don't understand what you mean by this, the new fan of the ceiling is generally the pipe in the ceiling, one end is connected to the machine and the other end is outside.
I think that the brand of Yuanda ceiling fresh fan is better, energy-saving and environmentally friendly, with better performance and more repurchase rate.
If you buy a ceiling fresh fan, not only should the fresh air effect be good, but also intelligent, so that it is good to use, I personally recommend Rongken fresh air, the fresh air effect of their ceiling fresh air fan is good, and according to the indoor air quality, automatically adjust the wind speed, enter the mode that matches the current environment, very intelligent.
