Optimized Ventilation


Reduce Air Change Rates, Save Energy

Traditionally, laboratories are designed with a fixed number of air changes per hour (ACH), usually between 6 and 12, but sometimes up to 18 for a vivarium. This type of design uses a pre-determined setpoint and typically results in over-ventilation. According to ANSI Z9.5, 2022, the ventilation rate may vary based on measurements of specific contaminants at selected locations in the room or in the exhaust duct connected to the room.


Reducing ventilation in laboratories based on environmental sensing offers opportunities for energy conservation. This approach can safely reduce lab air change rates to as low as 2 ACH when the lab air is “clean” and the fume hood exhaust or room cooling load requirements do not require higher airflow rates.


AntrumX™ allows laboratories to use dynamic ventilation systems, as specified in ANSI Z9.5, based on real-time information to vary ventilation rates while providing a safe and information-based approach to dilution ventilation. With AntrumX, it isn’t necessary to set a constant ventilation rate. Instead, a range of rates can be used, with real-time values determined according to sensed operating data.


AntrumX’s patented technology uses zero moving parts to draw air from the zone to the monitoring panel. That means zero loud, maintenance-intensive pumps and zero contaminated air samples pumped back into the building.
