I've been asked by a client to put right his existing ventillation to his 2 x ensuites and main bathroom.

All 3 rooms have a separate in-line fan mounted into the same loft area but none are exhausting externally. They are pumping condensation into the loft!

The loft area is of the warm roof type and the customer is unwilling to vent these fans via roof vents.

The nearest external access point is 10m away which is too long for the small inline fans.

3 x axial fans could come in at about

 
I think as noz says the manrose cfd fans should be ok for this distance. I have used them on long distances before with no problems. I personally would put one hole out for each fan but at the end of the day you have to price it up and see what customer will pay.
