Our range of CAV airflow monitors and VAV airflow controls utilise a unique airflow sensor that is used to measure face velocities or duct velocities. The sensor has no inherent drift and provides stable accurate readings over many years of operation without the need for recalibration.
The AFA500 and AFA1000 series of airflow monitors are specifically designed to ensure the safety of users of industrial fume cupboards, educational fume cupboards, fume hoods and biosafety cabinets. Over 400,000 airflow monitors can be found in laboratories across the world and the name TEL is synonymous with high performance and safety.
The AFA1000/E series of VAV airflow controllers are designed to provide VAV control and ensure the safety of users of industrial fume cupboards, educational fume cupboards, fume hoods and biosafety cabinets. Our VAV control systems are helping organisations meet carbon reduction targets, reducing energy usage by up to 85%, reducing operating costs and, at the same time, carbon footprint. A full retrofit solution is also available on existing CAV systems.
Companies can maximise energy and cost savings and provide even greater safety for fume cupboard operators by introducing TEL’s innovative auto sash controller. It has been specifically designed to close the sash automatically when the operator is not present in front of the fume cupboard.
