Inline Flue-Gas Exhausters
Increase airflow through exhaust duct to improve furnace performance. Create a cutout in your duct, insert the blower wheel, and mount the housing to the duct. All have an open dripproof motor enclosure for relatively clean, dry, indoor locations. They cannot be used for sidewall venting applications.
Optional safety switch (sold separately) prevents furnace from firing if exhausters fail.

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.
