FDM06-L-L2 Overflow Type for Positive and Negative Pressure Airflow Monitoring｜Guarding the Invisible Boundary of Airflow Direction
In critical environments, airflow direction matters more than pressure level — it determines whether contaminants are blocked or carried outward.
In pharmaceutical, semiconductor, and other precision environments, air must flow in a defined direction to maintain cleanliness and safety. When positive and negative pressures become unbalanced, reverse airflow may occur, causing particles or contaminants to spread. The FDM06-L Overflow type adopts a hot-wire airflow sensing principle that directly detects extremely small airflow velocity and direction, rather than merely measuring differential pressure values. Through real-time airflow monitoring, engineers can clearly determine whether the space remains under positive or negative pressure and quickly adjust ventilation and filtration systems to ensure airflow control within critical environments always stays in a safe and stable range.
