Stainless Steel Roof Turbine for House Chimney/Attic Exhaust Vent, Round Ball Shaped Air Exhaust Cap, Non Power Ventilation Grille Cover (Size : Dia.300mm)

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 SteelDia.100-200mm - Suitable for pipe, clamp installation.Dia.300mm - 450mm- 90° fixed feet installation.Dia.500-600mm - Adjustable angle. Base plate installation(With Blue metal base).Features :- 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.Package List :- 1× Roof Turbine (Includes Accessories).Notice :- The edge area of \u200b\u200bthe stainless steel vent is sharp, please be careful!- Please wear gloves when installing!- 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.

• 【Wide Application】Suitable for chimneys, farms, factory roofs, ventilation ducts, warehouses of vent pipes/hoses, bathroom vents & extractors, air conditioning units, kitchen fans & vents.
• 【No Noise & Rainproof】Roof vent turbine has low noise during spinning. Encrypted blade clearance is small enough to prevent rain from entering the ventilation . Also keeps out birds and rodents.
• 【Stainless Steel Roof Turbine】Made up of thickened stainless steel material, rainproof, anti-rust, high hardness, and durable, easy to clean.
• 【No Power Chimney Cap】The use of natural wind and indoor temperature difference caused by air heat convection to push the turbine to rotate, so as to use centrifugal force and negative pressure effect to expel indoor fresh air.
• 【Easy to Install】100-400mm is no need to assemble, you just take it out and install it where you need it; 450-800mm needs to be assembled, and you need to be patient to complete it. Including all installation accessories.
