## Questions & Answers

**Q: Does the damper work when the air is pulling as opposed to pushing?**
A: it only allows the air to flow in one direction, whether that be on the vacuum or pressure side of the fan. I installed mine on the cold-air-return side of the furnace (vacuum side) and on the vacuum side of a duct fan to pull cold air from the house towards my basement wood stove.

**Q: Will the 12.5 inch work with a 10 inch diameter exhaust fan and duct work?**
A: The 10 inch is the diameter of the opening,works with the 10 inch duct

**Q: Will it rust because of rain when exposed outdoors？**
A: Aluminun doesn't rust

**Q: The max 245mm diameter model is for a 10" pipe, however the selections don't offer a 10" model only a 12" model.  Is this a typo?**
A: Bigger is often better
