Barometric Draft Dampers

These dampers improve furnace performance by automatically opening and closing to maintain a consistent airflow despite changing environmental conditions.

Single-Acting Damper—Single-acting dampers open inward to prevent strong drafts from pulling too much heat into the chimney vent.

Double-Acting Damper—Double-acting dampers open both inward and outward to relieve pressure caused by obstructions and downdrafts.
