## Questions & Answers

**Q: Is the effectiveness of the extractor reduced significantly when you extract from 150mm to 100mm?**
A: Good evening,
As you are only extracting predominately steam we have experienced no reduction in performance. It is also dependent upon the efficiency of the fan, motor & filters. It pays to clean the filters regularly, this is easily done in a dishwasher say, once a month if you are using the extractor every day. Hope this has helped.
Regards
Geoff

**Q: Will standard 150mm flexi hose ducting fit over the end or will i need another connector/adaptor?**
A: No the 150mm end is female so it’s designed for a pipe to slot into the hole. You could hold the hose in place with foil tape / gaffa tape or try and buy and male to male adaptor

**Q: can i attach this straight onto existing hose or do I need a metal ring clip?**
A: you will need to clip or tape in place at the 100mm end as this is a male fitting
however the 150mm end is a female fitting and will not work with 150mm flexi hose - only solid PVC pipe 
as it will sit over the pipe

**Q: Can i attach this to the kair 150mm y piece as the internal measurements for reducer are 147.30mm & external for y piece are 149.40mm?**
A: I used the 150 reducer to come of a extractor 
Hood over a cooker which is 150mm and l attached it to a flexible pipe that went out though the kitchen wall which is 100 mm
So it only works if one end is 150mm and the other end is 100mm
