China ventilation fan motor factory, ventilation fan motor variety is complete, room ventilator - natural ventilator natural ventilator depends on indoor and outdoor temperature difference, air pressure and other air pressure to achieve ventilation window ventilator.Ventilators that rely on indoor and outdoor atmospheric pressure (air flow) and temperature to determine ventilation.Natural ventilator is small in volume, and the ventilation effect is affected by the environment, and the sound insulation effect is slightly poor. It can not dust the fresh air entering the room.Whether in the installation, structural design, material selection and other aspects are fully taken into account the different use of the situation, safety, high reliability;7. Insect and dust proof: there are insect and dust proof nets on the ventilation passage.
Room Ventilators - Wall Hanging Ventilators: A wall hanging ventilator is a ventilator that hangs on the wall.By drilling a hole in the wall to arrange the intake and exhaust pipes, so that outdoor air in and indoor air out.Complete organized ventilation, solve high-rise civil buildings and public building window ventilation, heating areas in winter, hot areas in summer air conditioning ventilation energy loss and other issues.It is suitable for supplementary ventilation of central exhaust system of public buildings and residential buildings which need to reduce the influence of noise at the side of urban traffic roads.Usually applied to the built, Windows are not easy to change the building.The maximum sound insulation is 51dB.It has the function of reducing or eliminating noise at the same time of ventilation and ventilation.
