SHANTHI Aircooler in palladam A roof exhaust fan is a type of ventilation system designed to remove hot, stale, or polluted air from a building or industrial facility. Installed on the roof, these fans help improve air quality and maintain a comfortable and healthy indoor environment by allowing for the continuous exchange of air. Roof exhaust systems are commonly used in both residential and industrial applications. Key Features of a Roof Exhaust Fan: 1. Airflow Management: The primary function of a roof exhaust fan is to expel hot air, moisture, odors, smoke, or pollutants from inside a building to the outside, helping to maintain a balance in airflow. This helps reduce humidity and prevents the buildup of contaminants inside. 2. Temperature Regulation: In industrial and commercial settings, roof exhaust fans are often used to expel heat from machinery, reducing the temperature inside the building and preventing overheating. 3. Energy Efficiency: Roof exhaust systems typically use less power than air conditioning units, making them a cost-effective way to improve ventilation and reduce energy consumption. 4. Types of Roof Exhaust Fans: Axial Roof Exhaust Fans: These fans use blades that push air in a specific direction and are suitable for situations where large volumes of air need to be moved with less resistance.
