Specifications
1.rainproof,no power,2.neck tube angle endue to be installed on 0-22.5 degree slope
3.imported bearing,quality assurable
specifications:
1. the special neck tube angle can make the roof fan installed on 0-22.5 degree slope,very easy install.
2. curved blades are the best results of scientific calculation and it can strictly ensure that no rainwater intrusion.it can start work when the breeze up to 0.2metre/s or the temperature gap up to 0.5 degree.
3. central axis with fine steps,the turbine blades never deformed and extend the life.
4. Imported bearings ensure the quality.
5. UBC high precision bearing system is fully closed and can permanantly self-lubricating,it can start work even if the breeze is less than 2km/hour
6. it is driven by natural wind or the air convection of indoor and outdoor tmeperature gap,exhausted the not fresh air by centrifugal force and negative pressure.
