Each type of HVAC system falls into one of two categories: ducted or ductless. A ducted system utilizes a primary unit to propel air through a network of ducts, regulating the temperature of a building. Conversely, ductless systems operate without air ducts and employ alternative mechanisms to disperse conditioned air within a given area.

A ductless exhaust provides a short channel for the airflow to pass through, while a ducted exhaust provides a pathway to move the air far away.
With cooker hoods they suck in air... the air has to go somewhere. so it can either can back in the room (recirculated, usually through filters) or they can be ducted out. where ducting is the pipes that take it away.I haven't heard of a machine that is non ducted but i can assume that there isn't an attachment to connect ducting to.

A ducted RC airplane has both the motor and 'propellar' within the body. Technically, the 'propellar' is more of a multi-bladed or faceted fan, and the part of the body within which it's contained is referrred to as the 'duct'. The whole assembly is then referred to as a 'ducted fan' RC plane, which has been subsequently referred to as a ducted RC plane. A non-ducted RC plane would be a conventional plane that you might be used to seeing, with the propellar plainly visible.
Ducted fans can be purchased at most any hardware store such as Ace, Home Depot or Lowe's. There is also a website called Ductedfans that also carries the fans.
