💡 How to keep a heavy duty motorized ventilation damper running smoothly through seasonal weather changes
This handy system depends on tight seals and consistent motor torque to block unwanted drafts
- Inspect the galvanized finish regularly to stop surface rust from gumming up the pivot pins
- Wipe down the silver coating every few months to prevent salt buildup near coastal job sites
- Verify the ninety degree opening clears fully so your exhaust fan never pushes against restricted airflow
