Roof Rotating Vent Cap, 304 Stainless Steel Turbines Ventilator Vents Roof Wind Turbines Cap Vent, Exhaust Cap Roof Flue Vent, Round Ventilation Exhaust Heat Dissipation(110mm/4.3in)

Roof VentilatorZero consumption:Using natural wind and air-heat convection caused by the temperature difference between indoor and outdoor to drive the turbine to rotate,In this way, centrifugal force and negative pressure are used to discharge the stale air in the room. Features:--Rotating cover for ventilation pipes, chimneys and air extraction. The protective gear provides a maximum protection without affecting the performance of the chimney.--The rotor antissinking air current is suitable for most standard chimney pots to prevents wind and increase ventilation.--The hat is designed to rotate with the wind, so the more wind blows, the more the leaves rotate, and the strongers the wind from the inside out.--Can be installed on slopes of 0-22.5 degrees, flat or inclined, with high exhaust efficiency. Specifications:Name: Roof VentilatorMaterial: 304 stainless steelAdvantages: discharge indoor hot air and dirty air, purify the indoor environmentPrinciples: Utilize natural wind and indoor temperature difference, air -to -flow drives turbines rotation. Eliminates the old air in the room with centrifugal force and negative pressure.Application: For the ventilation of exterior walls such as bathrooms, kitchens, warehouses, residences, apartments, etc.Size: 110mm/4.3in , 160mm/6.3in , 200mm/7.9in , 250mm/9.8in , 300mm/11.8in , 350mm/13.8in , 400mm/15.7in , 450mm/17.7in , 500mm/19.7in , 600mm/23.6in Package Contents:--1 x Stainless steel top cover (With Accessories) Note:--Due to light and personal differences in color understanding, there will be small color differences in kind.--Due to different measurement methods, the error is generally 1-3 cm and the error range is not within the quality range.
