Understanding Negative Airflow Rooms: How to Optimize Indoor Air Quality and Ventilation

Negative airflow rooms are designed to create a pressure differential that prevents contaminants from escaping into adjacent spaces. This design is particularly crucial in settings like laboratories, hospitals, and industrial facilities, where controlling the flow of air is vital for safety and regulatory compliance. In a negative airflow room, the air pressure is lower than in the surrounding areas, ensuring that any airborne pathogens or pollutants are contained within.

Tips for Designing Negative Airflow Rooms:

1. Ensure proper sealing: Use airtight materials and techniques to prevent leakage and maintain the negative pressure.

2. Utilize high-efficiency particulate air (HEPA) filters: These filters can trap particulates and improve air quality.

3. Monitor airflow: Regularly check the pressure differential with manometers or pressure gauges to ensure compliance with design specifications.
