Integrated with a gas sensor, the equipment monitors carbon filter saturation status to protect operators from chemical contaminants
Temperature Electronics Ltd (TEL), an electronic airflow control and monitor manufacturer and consultant, has upgraded its technologies to incorporate an organic vapour type gas sensor.
The AFA4000/E/GS airflow controller, as well as the AFA4000/1/GS and AFA4000/2/GS CAV airflow monitors are integrated with a gas sensor. This allows operators to monitor carbon filter saturation status and protect operatives from chemical contaminants.
“Our AFA4000/E/GS airflow controller and AFA4000/1/GS and AFA4000/2/GS CAV airflow monitors with integrated gas sensors enable laboratory managers to efficiently ensure the respiratory protection of users against dangerous chemical contaminates,” said TEL director Richard Eady.
Carbon filters absorb gaseous chemical contaminants but must be replacement regularly to ensure their effectiveness.
The sensor detects breakthrough, triggering an alarm to indicate the urgent need for filter replacement. This prevents saturation, which compromises filtration and causes gas to leak and risk the respiratory health of operators.
TEL’s integrated AFA4000/E/GS VAV, AFA4000/1/GS and AFA4000/2/GS CAV allow operators of filtrated type recirculating fume cupboards, hoods and cabinets to monitor filter saturation status with a dynamic graph.
The integrated units also set off an alarm when the filter has completed its manufacturer-designated hours and is due for replacement by counting the filter’s run time.
While the units can be incorporated into cupboards, hoods and cabinets during the construction stage, they can also be retrofitted into existing equipment.
