Is the effectiveness of the extractor reduced significantly when you extract from 150mm to 100mm?

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

Will standard 150mm flexi hose ducting fit over the end or will i need another connector/adaptor?

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

can i attach this straight onto existing hose or do I need a metal ring clip?

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

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?

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
