Furnace Draft Dampers
Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain a consistent airflow despite changing environmental conditions.
Single-acting dampers open inward to prevent strong drafts from pulling too much heat into the chimney vent.
Double-acting dampers open both inward and outward to relieve pressure caused by obstructions and downdrafts.
