If you’re preparing for the annual certification of your biological safety cabinet (BSC) or an initial certification because you have a new or just repaired fume hood, it’s an ideal time to install the Rooster Airflow Alarm to monitor BSC airflow. It provides real-time tracking of air velocity, which allows you to detect any airflow issues immediately. The BSC airflow alarm system alerts users with audible, visual, and remote alarms when airflow drops to 20% of the calibrated operational flow, in accordance with NSF/ANSI 49 requirements for Type A1, A2, and B cabinets.
The airflow monitor has flexible sensing options. Its probe sensor is preferred by users looking to meet NSF/ANSI 49 requirements, and is typically inserted into the exhaust duct, on the clean side of the HEPA filter. The sidewall sensor is well suited for monitoring sash airflow and for applications where the exhaust flow stream is hot or dirty. Additionally, to update airflow monitoring in BSC retrofit situations, a special inline sensor is offered.
Quick and easy to install and configure, the Rooster BSC airflow alarm features a single-step calibration where you press a button with the critical containment cabinet operating. When the status LED on the front face of the alarm is green, it indicates safe airflow and healthy operation. Red indicates that the air stream is below user-defined threshold levels, and the audio alert announces in conjunction with the visible alert. Connect to the airflow monitor’s NO or NC alarm relay output for remote signaling.
For users who want to see measured values and airflow status in real time, the next-gen Rooster Monitor100 addresses this requirement. Monitor100’s color touchscreen display works with or without gloves, and full-screen background colorization conveys the current state.
