Fume cupboard manufacturers now have access to a new airflow controller with integrated gas sensor, enabling laboratory managers to efficiently monitor carbon filter saturation status and protect operatives against chemical contaminates.

UK-based specialist electronic airflow control and monitor manufacturer and consultant, TEL, has upgraded its energy-efficient AFA4000/E VAV (variable air volume) airflow controller to incorporate an organic vapour type gas sensor. 

Carbon filters absorb gaseous chemical contaminates and TEL’s integrated AFA4000/E/GS solution enables laboratory managers using filtrated type recirculating fume cupboards, hoods and cabinets to monitor filter saturation status via a dynamic graph.

When saturation occurs, filtration is compromised and gas escapes.  The sensor detects breakthrough, triggering an alarm to highlight the urgent need for filter replacement to ensure the respiratory protection of users.

The integrated unit also counts the filter’s time-run, sounding an alarm when it has fulfilled its manufacturer-designated hours and is due for replacement.

In addition to incorporating the unit into cupboards, hoods and cabinets at initial construction stage, manufacturers may retrofit it into any existing equipment, allowing laboratory managers to improve the safety and efficiency of their facilities cost-effectively.

Said TEL’s director, Richard Eady: “Our AFA4000/E/GS airflow controller with integrated gas sensor enables laboratory managers to efficiently ensure the respiratory protection of users against dangerous chemical contaminates.”
