从China供应商批发进口20inch Natural Power Roof Air Ventilator — FOB条款

The 20inch natural power roof air ventilator operates on the principle of thermal convection, transforming horizontal airflow into vertical movement to enhance indoor ventilation efficiency. The model AP20inch features a turbine diameter of 630mm with a ventilation diameter of 500mm, and the total unit height measures 520mm with a base plate diameter matching the ventilation opening at 500mm. The system utilizes 25 stainless steel blades engineered to capture natural wind energy and convert it into rotational force, eliminating the need for electrical power consumption during operation.

The ventilator body is constructed from stainless steel, providing resistance to corrosion, moisture, and environmental degradation in industrial and commercial settings. The listing specifies American UBC bearings for the rotating assembly, which are pre-lubricated and designed for maintenance-free operation under continuous use. All supporting brackets are manufactured from stainless steel to ensure structural integrity in harsh conditions including high humidity environments, coastal installations, and facilities with chemical exposure. The unit is designed for installation on flat or slightly sloped roof surfaces where natural wind patterns can drive the turbine rotation.

This roof ventilator is suitable for installation in warehouses, manufacturing facilities, workshops, sports stadiums, tennis halls, assembly areas, garages, paper mills, galvanization plants, and coating factories where effective heat removal and air exchange are critical. The target buyers include facility managers, industrial plant operators, and construction contractors seeking passive ventilation solutions that reduce energy costs while maintaining air quality. Prospective importers should verify the specific stainless steel grade used in the blade assembly and bearing housing, confirm the packaging details for sea freight, and establish whether the supplier provides installation hardware or mounting kits as part of the standard shipment.
