SHANTHI AIRCOOLER IN PALLADAM A roof exhaust fan is a mechanical ventilation system typically installed on the roof of buildings to help expel hot air, moisture, and odors from the interior. These fans are often used in attics, warehouses, factories, and residential homes to maintain air quality, reduce heat buildup, and prevent the accumulation of moisture, which can lead to mold or mildew growth. Key Benefits of Roof Exhaust Fans: 1. Temperature Control: Helps reduce heat buildup in the attic or upper parts of a building by expelling warm air. 2. Moisture Control: Reduces humidity, preventing mold and mildew growth. 3. Energy Efficiency: Improves energy efficiency by reducing the load on air conditioning systems during hot weather. 4. Air Quality: Helps remove stale air, odors, and other pollutants from indoor spaces. 5. Protects Roofing Materials: By reducing heat and moisture, roof exhaust fans help prolong the lifespan of roofing materials. Types of Roof Exhaust Fans: 1. Powered Roof Exhaust Fans: These are motor-driven fans that require electrical power to operate. They are often more effective in large spaces or areas with heavy air buildup. 2. Passive Roof Ventilation (Roof Vents): These are static vents or turbine vents that rely on natural airflow to push hot air out of the building. These do not require power. 3. Solar-Powered Exhaust Fans: These fans are powered by solar energy
