In a cleanroom, you can typically find three types of airflow patterns: laminar, turbulent and a combination of both.  All of these airflow patterns use high quality HVAC units, as well as HEPA or ULPA filters.


  • Laminar: The air flows in flat layers, typically from the ceiling straight down to the floor.
  • Turbulent: The air flows in different currents through the room from filtered air ducts and is absorbed back through grilles in the walls or support columns.
  • Mixed: Uses both laminar and turbulent airflows, typically sectioned off for different areas of the cleanroom.


Rooms with a higher need for cleanliness typically choose laminar flow, whereas rooms that don’t handle critical processes typically opt for turbulent or mixed airflow.  Contact us today to learn more about the proper kind of airflow for your cleanroom.
