Airflow Alarm Makes a Positive Impact on Fume Hood Safety

Do you want to improve laboratory safety?

Airflow Alarm, three sensor types

If your fume hood does not have a means to verify airflow, or uses a legacy magnehelic gauge, the addition of the Rooster Airflow Alarm is recommended. A properly functioning fume hood is often the most important engineering control in a laboratory; the Rooster Alarm continuously tracks fume hood face velocity to help make certain that containment is adequate, and employees are protected.

Unlike the outdated method of inferring air velocity and thus fume hood performance from the differential pressure reading of a magnehelic gauge, the Rooster Alarm measures air velocity within a fume hood. It provides audible and visual alarming, and actuates a relay, to alert users to low airflow conditions. The Rooster’s flashing green LED indicates safe air velocity and operation within the calibrated range, while a flashing red LED indicates unsafe airflow.

With a single press of a button while the containment unit is operating, the fume hood monitor can be calibrated at known safe airflow or at the alarm trip point. If calibration at known safe flow is selected, the airflow monitor will alarm when there is a 20% loss of flow, in accordance with NSF/ANSI 49 requirements.

Whether you’re remodeling a fume hood, or installing a new one, include the Rooster Airflow Alarm. It’s a small step that makes a big impact.

If a digital readout of fume hood air velocity is desired, our color touch screen airflow monitors display air velocity and temperature measurements in real time.
