Do you need to retrofit the airflow monitor in your Class II biosafety cabinet?
Biosafety cabinets need the ability to monitor airflow and present airflow status to the user. By NSF/ANSI Standard 49 requirements, a biosafety cabinet must have audible and visual alarms that indicate a loss of exhaust airflow. The Rooster Airflow Alarm with probe sensor will satisfy these obligations, providing full-time tracking of air velocity in your exhaust system and initiating audible, visual, and remote alarms for canopy low flow or loss of exhaust.
Easy Installation – Installing the airflow alarm system is straightforward:
- Mount the sensor.
- The duct-mounted probe sensor is typically mounted on the clean side of the HEPA filter.
- The curve in the sensor probe serves as a guide to align the sensor head in the direction of airflow. Adjust the gland nut to achieve the desired probe insertion depth.
- Use the dip switches on the back of the alarm module to configure calibration settings and alarm behavior.
- Make power and wiring connections.
- Mount the alarm module.
Connectors are readily accessible at the top of the alarm module, so if preferred, it’s no trouble to make connections after mounting the Rooster.
Simple Field Calibration – Sensor calibration is performed with a single button press while your containment unit is operating. When you see the green LED, the calibration sequence is complete and your Rooster airflow alarm system is up and running, monitoring air velocities.
NSF 49 Compliance – As required by NSF/ANSI Standard 49, if there is an exhaust volume loss exceeding 20%, the Rooster will alert the operator with a visual and audible alarm.
Ask about the Rooster’s optional NSB (night setback) feature if your system reduces airflow during non-working hours for energy savings.
The Rooster airflow alarm system has flexible sensing options. A sidewall sensor is available for monitoring face velocity and a special inline sensor provides flexible mounting and backwards compatibility to other airflow monitor systems. Schools and universities often choose the inline sensor to increase the tamper resistance of the system by mounting the sensing element inside the cabinet plenum area.
