Product Details
The Edwards SD-T18 18-inch Sampling Tube is engineered for use in duct smoke detection systems requiring accurate air sampling in medium-width ducts. Designed specifically for ducts up to 18 inches wide, this tube allows smoke detectors to monitor airflow effectively and detect smoke particles before they spread throughout the building.
Because the tube channels airflow directly into the sensing chamber, it plays a vital role in ensuring early warning and code compliance in HVAC-based fire detection systems.
