Natural Smoke & Heat Ventilation

Natural Smoke & Heat Ventilation

Natural Heat & Smoke Ventilation can help save equipment, the building, and most importantly, workers’ lives in the event of a fire. A fusible link opens the vent automatically in the event of a fire; allowing the smoke to escape the building. Some of these devices are not used for general building ventilation.
