So if you put an inline fan halfway along the duct, are you effectively able to use more duct length with it than you would be able to if you put the same fan at (or near) one end?

It's 1m of flexi then 8m of rigid

The Vent Axia has a constant trickle, plus a pullcord that turns on the boost which takes it up to 60 L/s. So the Vent Axia just needs a permanent live connection. My existing fan is wired to a light switch (but with no lights on the circuit). Would it be ok to just wire the existing live from...

No it's already installed

Thanks both. Flameport, am I right in thinking that outlet pressure is not something manufacturers will be able to tell you? It will depend on the specific installation and you'd have to measure it after the install is done?

Thanks John. That fan has basically the same flow rate as the Vent Axia. By better ducted, do you mean that it's better cos it's an inline fan? Or just better manufactured? (I can't find a maximum ducting length in their technical specs.)

Hi, I'm having an extractor fan fitted for an internal bathroom (with shower). The duct length to reach the outside wall is 9m (ducting is under floor) and is 100mm wide. I've found a fan - the Airflow Icon 30 - which has a flow rate of 33l/second and which teh manufacturer says can work over...
