Ducted and Non Ducted Ceiling Exhaust Fans

Non-ducted fans are generally very simple in design and work by moving air/steam from a room to the roof-space above it. They often do not have the ability to be ducted in any way, and are often a cheap solution if there is little need for steam to be completely removed from the roof-space (ie if you have a tiled roof with natural ventilation).

A ducted fan on the other hand are generally more complex, possessing motors designed to pull the air/steam from a room and direct it sideways above the ceiling through an opening in the motor housing. Ducting can then be attached to this opening so that the steam in the room can be evacuated where desired.
