One of the most important aspects of cleanroom design is HVAC and airflow in the room. In addition to incorporating a robust HVAC control system and HEPA filters, many cleanrooms also include pressurization. Positive pressurization is particularly beneficial to rooms that handle sensitive processes.
Air typically flows down from the ceiling through HEPA filters, sweeps the floor and is exhausted through grilles in the wall. The air is then pumped back up to the ceiling where it is sent back through the HVAC units. Continue reading Cleanroom Pressurization
Cleanrooms are used for many different processes ranging from the production of medications to creating microchips. Although the cleanrooms look similar to normal rooms with features like walls and doors, they are actually quite different. One of the main differences that set cleanrooms apart from other rooms has to do with airflow.
In a standard office, HVAC units typically produce two to ten changes of air per hour. Continue reading The Cleanroom Difference
