 Negative Pressure Isolation Rooms maintain a flow of air into the room, thus keeping contaminants and pathogens from reaching surrounding areas. The most common application in the health industry today is for Tuberculosis (TB) Rooms. The infectivity of TB is extremely high and these rooms are essential to protect health workers and other patients.
The CDC recommends 6-12 air changes per hour (ACH) for TB Rooms. An ante room is always recommended, as this provides a barrier between the TB Room and hallways and limits the impact of opening doors and traffic. The exhaust air is filtered through the HEALTHY AIRTM with the advanced eHEPATM filter before being introduced to the outside of the room, or partially recirculated within the room. The high energy eHEPATM effectively kills and eliminates any harmful microorganisms, thus making the exhaust harmless.
The exact air pressure differential which is required to be maintained is nominal only, as it merely indicates the airflow direction. It is sometimes stated as 0.001"wg, but this is not a pressure which is practical to measure, and therefore other criteria are given such as maintaining an inward velocity of 100 fpm, or exhausting 10% of the airflow, or exhausting 50 cfm more than the supply. The exact criteria will always be dependent on both the size and the airtightness of the subject facility.
