Description

The VESDA VLI filtration system effectively reduces the level of pollution in the air sample before it enters the detection chamber, which dramatically extends the operational life of the detector in harsh and polluted environments. It is fully monitored, therefore it provides consistent sensitivity over the entire operation life of the detector.
To maintain the operational integrity of the detector, it is recommended that the Secondary Foam Filter be replaced every 2 years, or when a filter fault occurs or more often for environments that experience high levels of contamination.
