Advantages of  Ampelair  type 500  no power ventilation         

                                       
Ampelair type 500 natural ventilator is mainly composed of   turbo head, waterproof substrate and a diameter of 500mm variable angle tube neck .

1、High-efficiency ventilation

According to the wind mechanic principle designed arc-shaped turbine blades and excellent low friction force bearings, even though in light winds it can rotate  continuously  to exclude the indoor - polluted air .

2、Strong and corrosion-resistant stainless steel body airframe

High-quality stainless steel body can withstand a long period of hard weather and resist  against indoor-corrosive gases .Low friction force sealed bearings and durable lubrication need no maintenance.

3、Easy installation

Because of the use of a unique rariable angle tube neck design, Ampelair ventilators can apply to different  angle (0o-22.5o) Roofing, greatly reduces installation costs.

4、Environmental protection, energy saving, no need  electricity

After natural ventilation is installed, only the natural wind can make it  work continually wiht  high sensitivity  , durablity and no noise.
