No Powered Wind Force Roof Wind Ventilator

Structure of natural force ventilator

1 Turbine head
26, 32, 42 vanes is the optimum result of scientific calculation
Special middle shaft and shaft clip design
Full sealed high performance Japanese bearing
2. Variable angle tube neck
Change the angle of tube neck according to different roof inclination (0~22.5°), keep the strict verticality of turbine head to the ground.
The baseboard is made of stainless steel or color steel according to the different wave deformation of roof color steel plate.
3 Excellent performance
(1).Unique variable angle tube neck, which makes the installation on 0~22.5° roof very convenient.
(2).High efficiency exhaust ability is 25% better than the products of the same type (refer to exhaust efficiency comparison table)
(3).Unique vane design, no water leakage.
(4).Unique movable bearing and shaft clip, make the bearing exempt from longitudinal pull and prevent the vane from permanent deformation.
(5).Full sealed Japanese high quality bearing, firm and durable, no need to maintain, no noise.
(6).Can bear the wind speed of 200 kilometers/hour and rainfall of 200mm/hour without being damaged or water leakage.
