• 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.
• Sturdy stainless steel construction: choose the size according to the outside diameter of your chimney. Our chimney caps are made of thickened 304 stainless steel, which is water and heat resistant. Sturdy design, no need to worry about frame deformation in bad weather. Can be used outdoors for years to come, saving you replacement costs.
• Roof vents: Rotary 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.
• 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.
