## Questions & Answers

**Q: Hi i have purchased a fantronix inline bathroom fan model: ftx-tube-100-t. will this fit the outlet of the fan and the flexible ducting?**
A: These connectors are two male ends to the female ends of either rigid pipe or flexible ducting.  Most fan outlets/inlets are male ends designed to, again fit the female ends of either rigid pipe or flexible ducting.  Therefore you may need to use a short length of either.  Cutting flexible ducting is easy enough with scissors or a sharp knife through the plastic & then cutting the wire helix with pliers.  Make sure the none-return flap hinge sits horizontal & is facing the right direction & on the outlet flow of the fan, it may need to be supported some way. Personally I prefer rigid ducting.

**Q: Can it be fitter vertically? (My pipe goes vertically)**
A: The flap depends on gravity to close - I don’t believe this would work in a vertical position but I could be wrong

**Q: Which way round does it fit**
A: It opens in the direction you want the air to flow. By blowing against the flap will determine which way it should be placed. It should positioned to close when a flow of air from outside is against the flap. The flap also needs to drop to the bottom when it closes by gravity.

### ⭐⭐⭐⭐⭐ Easy to fit
*by M***R on 28 February 2022*

Very easy to fit good product and value for money

### ⭐⭐⭐⭐⭐ No more drafts
*by D***E on 13 February 2024*

Perfect seal no more back drafts. Just to note it's a vertical instalation really as it closes with gravity.

### ⭐⭐⭐⭐ Did The Job
*by S***T on 26 September 2024*

I get a lot of draft coming through the bathroom extractor so I decided to get one of these. I was pleased with the product. The tube was thick and sturdy, but the flap was lightweight and a nice snug fit inside the tube. The flap was literally paper thin with 2 off-centre pins that held it into place. I simply took the extraction tube out of the wall, cut it in half and pushed the valve into place and pushed the other half of the tube over the opposite end. This product requires no DIY skills, and the job took me about 10 mins to install. The main thing, and most important thing is, I no longer have a harsh whistling draft gushing around the bathroom. Come the winter I will save money…no more drafts, or, cold temperatures, and for that reason it’s value for money. This product does exactly what it’s supposed to do and does it simply and effectively.
