System Sensor DST5 Metal Sampling Tube for DNRE and D2E, Duct Widths 4' to 8'

Designed to provide fast, reliable smoke sampling inside air handling systems, the System Sensor DST5 Metal Sampling Tube is an essential accessory for commercial duct smoke detection and monitoring. The DST5’s durable metal construction and 5' length make it ideal for HVAC applications with duct widths from 4' to 8', delivering consistent air sampling and early warning of smoke before it spreads through a building. Built for integration with System Sensor duct smoke detectors and the InnovairFlex product line, this sampling tube helps simplify installation and maintenance while meeting industry expectations for security, surveillance and life-safety monitoring. Ul-listed compatibility and a low-profile 1" depth/height make the DST5 unobtrusive in tight plenum spaces while remaining easy to access for periodic cleaning. For facility managers and integrators, the DST5 reduces false alarms and supports reliable detector performance across commercial and institutional HVAC systems. Add the DST5 Metal Sampling Tube to your duct detection layout to enhance HVAC smoke monitoring — order or consult with your distributor to specify for your project.
