Description
Edwards SD-T8 8-inch Sampling Tube
The Edwards SD-T8 8-inch Sampling Tube is designed for use with duct smoke detectors in HVAC systems with narrow air ducts. It helps deliver consistent airflow to the sensing chamber, allowing early detection of smoke and other combustion particles. At just 8 inches in length, the SD-T8 is ideal for smaller duct applications where space is limited, yet code compliance and system reliability remain essential.
Because of its compact size and compatibility with Edwards detectors, this sampling tube provides a simple yet effective solution for efficient smoke detection in tight spaces.
Built for Accurate Airflow Sampling
The SD-T8 is engineered to collect air samples from inside the duct and channel them into the smoke detector’s chamber. This ensures that the device can respond quickly to changes in air quality, even in short or low-volume ducts. The sampling holes along the tube’s length help draw a balanced airflow across the cross-section of the duct.
Unlike longer tubes, the SD-T8 offers a more compact footprint while maintaining reliable sampling performance. As a result, technicians can use it in confined mechanical rooms, low-clearance ceiling spaces, or short duct runs.
Durable and Easy to Install
Constructed from corrosion-resistant material, the SD-T8 performs reliably in demanding HVAC environments. Its rigidity ensures that it resists vibration and thermal stress, both of which are common in air-handling units.
Installation is quick and straightforward. The SD-T8 mounts directly into Edwards duct detector housings without requiring modifications. It includes an end cap that helps control airflow and prevents pressure loss, contributing to accurate detection and minimal maintenance.
Best Fit for Tight Duct Configurations
This sampling tube is ideal for use in schools, small offices, or retail environments where duct dimensions are minimal. Since it’s purpose-built for compact ducts, it allows engineers and contractors to design efficient systems without compromising on protection or performance.
The Edwards SD-T8 8-inch Sampling Tube provides efficient airflow sampling for compact duct installations. Its durable construction, easy installation, and accurate performance make it a reliable component in Edwards duct smoke detection systems. For projects requiring tight-space integration and reliable smoke detection, the SD-T8 offers both practicality and peace of mind.
