SHANTHI AIRCOOLER IN COIMBATORE A roof exhaust refers to a ventilation system or device installed on the roof of a building, designed to remove stale air, heat, moisture, and pollutants from inside the building. This system helps maintain air quality, reduce indoor humidity, and prevent the buildup of heat. Roof exhausts are commonly used in residential, commercial, and industrial buildings to improve energy efficiency and ensure healthy indoor air quality. Key types of roof exhaust systems include: 1. Roof Vents: Simple passive exhaust systems that allow hot air to naturally rise and escape. 2. Power Exhaust Fans: Active systems that use electric fans to pull air out of the building. 3. Kitchen and Bathroom Exhausts: Often installed to remove moisture, smoke, and odors from specific areas like kitchens or bathrooms. 4. Attic Ventilation: Helps prevent attic heat buildup and moisture issues that can damage a home’s roofing system. 5. Industrial Roof Exhausts: Larger systems used in factories or warehouses to remove fumes, smoke, or other contaminants. The choice of roof exhaust system depends on the building’s needs, the local climate, and the level of ventilation required.
