Roof fan noise barrier where to sell
Restaurants, cold stores, hotels or some entertainment will inevitably install the fans in the roof, such as exhaust fans, blowers, ventilation fans, induced draft fan, etc., they play the role of air flow, keep the indoor fresh air Or the combustion has an important role, but the installation of the fan is often accompanied by a strong noise, for the surrounding residents is unacceptable, it should be the rest of the time, the fan is still whirring operation, complaints of businessmen Countless. Fan off the big need, as long as the fan around the installation of the roof fan noise barrier, noise protection measures can be done.
Hanks roof fan noise barrier design: 1,
Hanks sound barrier type, there are perforated sound barrier, blinds sound barrier, concave and convex sound barrier, under the arc under the straight sound barrier, split angle sound barrier, curved sound barrier, mixed sound barrier , Straight flat sound barrier, the material on the FRP, PC board, spray plate, and other optional.
2,
Hanks roof fan insulation barrier with weather resistance, water resistance, heat resistance, anti-ultraviolet, will not be due to rain water temperature changes in performance or quality abnormalities. Surface galvanized treatment, anti-corrosion life in more than 15 years.

Roof fan noise barriers Noise reduction mechanism:
The noise reduction mechanism of the fan barrier is in the noise propagation, so that the sound waves are blocked by the barrier, resulting in reflection, projection and diffraction, the role of the barrier is to block the spread of direct sound, isolated transmission sound, and the diffraction sound has sufficient attenuation The The noise reduction effect of the sound barrier is related to the wavelength of the acoustic wave, the size of the barrier itself, the distance between the barrier and the noise source and the receiving point.
