How the fireplace cap works: The turbo fan uses 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, driven by wind, no electricity bill, reducing your expenses. Protects fireplaces and chimneys: Chimney hoods installed on top of fireplaces can withstand weather changes, protect chimneys from rain and moisture, and prevent powerful winds from entering the interior of ducts, chimneys, stoves, etc. to avoid adverse effects on smoky houses. It also keeps your chimney flue free from critters, birds, rain, snow, leaves, debris, etc. Roof vents: Rotary turbines can also be installed on roofs, sunrooms and other areas where air does not circulate.
