Why Every Extraction System Should Have an Airflow Monitor – And How Fumex Can Help

In workplaces where Local Exhaust Ventilation (LEV) systems are critical (workshops to laboratories and universities) maintaining effective airflow is essential to employee safety and regulatory compliance. One of the most effective and simple tools to ensure your LEV system is working properly is to fix an Airflow Monitor.

At Fumex Ltd, we offer both digital and analogue airflow monitors to give businesses peace of mind and that their LEV systems are working effectively.

Why Airflow Monitoring Matters

The Health and Safety Executive (HSE) states:

“There isn’t a specific legal requirement to have airflow indicators or similar fitted to an extraction system. But as an employer, you do by law have to make sure your LEV system keeps working properly.”

One of the main reasons LEV systems fail is a drop in airflow. This could be due to a build-up of dust or debris, damaged ductwork, or fan malfunction. When airflow drops below the certified level, hazardous substances are no longer effectively captured putting workers at serious risk.

An airflow monitor gives you a clear, continuous indication that your system is functioning correctly, helping you catch problems early before they become dangerous… or expensive.
