It also keeps your chimney flue free from critters, birds, rain, snow, leaves, debris, etc.
• How it works: Turbo fans use the principles of natural wind and air convection to improve indoor ventilation by accelerating parallel airflow into the vertical direction. Warm air rises and cold air falls, causing the fan to rotate, allowing heat, odors and dust to be efficiently discharged from the room. Energy saving, no electricity bill, reduces your electricity bill.
• Easy to install: Supplied fully assembled and ready for installation. One person easily completes the installation, saving time and effort. Create a sense of security for your friends, family and yourself.

• Non-powered roof vents: Rotating turbines can also be installed on roofs, sunrooms, and other areas where air does not circulate. Equipped with a durable ball bearing base, it requires only a small amount of wind to make it rotate automatically and is silent when rotating. No power supply is required to effectively exhaust heat, odors and dust from the room.
