Stainless Steel Non Power Roof Turbine Ventilator, 4/6/8/10/12/16 Inch Rainproof Chimney Exhaust Vent Cap Round, Attic/Farm/Factory/Chicken Coop/Kitchen Roof Vents

Roof Turbine solves the air backfilling caused by high winds and low air pressure, and avoids filling the home with oil smoke and odor. When the wind speed is 200 km/h and the rainfall is 200mm/h, the ventilator is still running intact without water leakage.Specifications :Material : Stainless SteelSize: Sizes AvailableFeatures :- No energy power, high speed, high precision, high density- Rainproof, anti-rust, high hardness and long service life.- Ensure Air Circulation: Provides maximum protection without hindering the performance of the chimney.- Enough strong to withstand 200km/h wind speed and 100KG load without damage and deformation.Easily Installation:Dia.110-200mm - Suitable for pipe, clamp installation.Dia.300mm-400mm - 90° fixed feet installation.Package List :1× Roof Turbine (Includes Accessories)Notice :- Please wear gloves when installing!- The edge area of \u200b\u200bthe stainless steel vent is sharp, please be careful!- Stainless steel produces magnetism during cold working. the greater the degree of deformation, the greater the magnetism. Therefore, It is normal that the magnet can be attracted.

• 【No Noise & Rainproof】: Roof vent turbine has low noise during spinning. Blades arranged closely, helps keep wind, rain and snow from entering outdoor dryer vents, also keeps out birds and rodents.
• 【No Power Chimney Cap】: The use of natural wind and air heat convection caused by the temperature difference between indoor and outdoor to drive the turbine to rotate, and exhaust the old indoor air.
• 【Wide Application】: Suitable for chimneys, farms, factory roofs, ventilation ducts, warehouses of vent pipes/hoses, bathroom vents & extractors, air conditioning units, kitchen fans & vents.
• 【Easily Installation】: 110-200mm is no need to assemble, can be installed with clamps to prevent gaps; 250-400mm needs to be assembled, can be installed with 90° fixed feet.
• 【Stainless Steel Roof Turbine】: Made of high quality 304 stainless steel material, galvanized bearings, zero energy, zero noise, anti-rust, corrosion resistance, weather resistant, durable and long service life.
