Q&A
Q: What is the XOMA08 make up air damper?
A: It’s an automatic 8″ round duct make up air damper set designed to bring fresh air into your home when your range hood exhausts air outside, helping balance indoor air pressure and improve ventilation.
Q: How does it work?
A: A feather switch senses airflow from your hood and automatically opens the damper when the hood is running, closing it when not in use to prevent unwanted actives.
Q: Is it easy to install?
A: Yes — it’s designed for 8″ round duct systems and can be mounted horizontally or vertically in your ductwork.
Q: What is the construction and finish?
A: Made from stainless steel for durability and outdoor suitability.
Q: Does it require power or control?
A: No external power is needed — it operates fully automatically via airflow sensing.
Q: Do local codes require make up air dampers?
A: In many areas, high‑CFM range hoods above ~400 CFM require a make up air system — this unit helps meet that requirement. (General HVAC understanding)
Maintenance Tips
-
Check the damper operation regularly — ensure it opens and closes smoothly with airflow changes.
-
Wipe stainless steel surfaces with a mild, non‑abrasive cleaner and soft cloth to remove dust and prevent corrosion.
-
Inspect linkage and moving parts occasionally for debris or buildup that can hinder movement.
-
Avoid harsh chemicals and abrasive pads that can scratch or dull the stainless finish.
-
Lubricate pivot points lightly (per manufacturer guidance) if movement feels stiff.
-
Verify proper sealing when the damper is closed to maintain balanced make‑up air performance.
