A KDK 8-inch in-line duct fan, delivering 519 CFM — installed inside the ducting itself rather than at the wall or ceiling, for internal bathrooms or kitchens that don't have a direct outside wall, or long duct runs that need extra push.
Do I need an electrician?
Yes — this installs inside ductwork, not as a simple wall/ceiling swap, so it needs an electrician or HVAC installer to fit correctly. It's the right solution when a standard wall or ceiling fan can't reach an outside wall.

FAQ
-
How much air does this move?
519 CFM (882 m³/h) — strong enough to push air through longer duct runs where a standard fan would struggle.
-
When would I need this instead of a regular exhaust fan?
When your bathroom or kitchen doesn't have a direct outside wall, or the duct run is too long for a standard fan to push air through effectively.
-
Can I install this myself?
No — this needs an electrician or HVAC installer since it fits inside the ductwork.
-
What's the duct size for this model?
200mm (8 inches) — confirm your ducting matches before ordering.
