System Sensor AX-DST5 Metal Sampling Tube, 5' Length

The System Sensor AX-DST5 is a 5-foot metal sampling tube designed for use with duct-mounted smoke detectors in HVAC systems. It extends into the air duct and uses strategically positioned sampling openings to draw representative air samples toward the connected smoke detector. The tube is suitable for duct widths from 4 to 8 feet and is compatible with conventional and intelligent System Sensor duct smoke detector applications. Its durable metal construction supports reliable operation in commercial and industrial HVAC environments. The DST5 is UL listed and provides a practical solution for extending duct smoke detection coverage across wider air-handling ducts.
