𝗧𝘂𝗿𝗯𝗶𝗻𝗲 𝗔𝗶𝗿 𝗩𝗲𝗻𝘁𝗶𝗹𝗮𝘁𝗼𝗿 𝗶𝗻 𝗽𝘂𝗻𝗲 A turbine air ventilator with a base plate is a type of ventilator that uses the wind to create a natural flow of air, which helps to remove hot and stale air from a building or enclosed space. The ventilator has a turbine-like structure that rotates as the wind blows, creating a negative pressure that pulls the hot air out of the building. The base plate is a mounting plate that is used to secure the ventilator to the roof or other surface. It provides a stable foundation for the ventilator and helps to prevent it from moving or being damaged by wind or other weather conditions.
