Powerless Air Ventilators, also known as passive ventilation systems, offer several benefits: 1. Energy Efficiency: Since they don’t rely on electricity or other sources, they consume no energy, making them highly energy-efficient and environmentally friendly. 2. Cost Savings: With no need for electricity or ongoing maintenance, powerless ventilators can lead to cost savings over time compared to powered alternatives. 3. Reliability: As they don’t rely on external power sources, they can operate consistently without interruptions caused by power outages or battery depletion. 4. Reduce Noise: Powerless ventilators are usually quieter than powered ones, providing a more peaceful and less disruptive environment. 5. Low Environmental Impact: By not consuming electricity or producing emissions, they contribute to reducing greenhouse gas emissions and overall environmental impact. 6. Passive Cooling: Passive ventilation can help cool indoor spaces by promoting natural airflow, which ca
