Working principle: use natural wind force and indoor and outdoor temperature difference to cause air heat convection, drive the turbine to rotate, so as to use centrifugal force and negative pressure effect to exhaust air
Effect: high precision, high speed, rain proof, fast air exhaust, large angle smoke baffle, cut off lampblack, and prevent lampblack from flowing backwards
Material: stainless steel, scratch and corrosion resistant, higher density, long service life
Details: galvanized bearing, compact blade, thickened stainless steel, free clamp, to prevent gaps in installation
