Differential pressure between two rooms prevents dust, particulates, and pathogens from entering or exiting one room and going into the other. Depending on the relationship between rooms, one room will be under positive pressure when referenced against the other. This positive-negative pressure relationship between two spaces is the main idea behind clean rooms and isolation rooms. To ensure the differential pressure relationship is maintained, a measuring device must be used.
Room pressure monitors and room status monitors measure, display, and transmit the differential pressure reading between two rooms. In general, room pressure monitors only monitor differential pressure. On the other hand, room status monitors monitor differential pressure and additional parameters such as relative humidity, temperature, air change, or door status. They are both used in critical applications that require critical low differential pressure relationships. Continue reading “What are Room Pressure and Room Status Monitors?”
Educational facilities, or public and private institutions devoted to teaching students, differ in physical size and level of education programs. These institutions can range from preschool to university levels, all of which need proper heating, ventilation, and air conditioning (HVAC) systems and indoor air quality.
The purpose of a healthcare isolation room is to prevent patients with contagious illnesses from spreading to others or to keep immunocompromised patients safe from exposure to airborne pathogens. As such, there exist two types of isolation rooms, either positively or negatively pressurized.
