• Stainless steel: The roof turbine ventilation is made of thickened stainless steel material, which does not rust, is waterproof and durable. Also easy to clean.
• No noise and rainproof: the roof ventilation turbine rotates silently. The encrypted wing spacing is small enough to prevent rain from entering the ventilation system. Also keeps birds and rodents away.
• Rotating chimney cap: thanks to natural wind and thermal air convection, which is caused by the difference between indoor and outdoor temperature, the turbine is rotated and the used indoor air is removed.
