What is a duct fan?
Duct fans are fans mounted between ventilation duct sections that move air along the duct. Because the fan is located inside the duct or between two duct sections, it is invisible in the living space, providing both an aesthetically pleasing and quiet ventilation solution. Bathroom and toilet shafts, kitchen exhausts, office and retail ventilation, and basement and storage areas are the main areas of use.
Category contents
- Inline duct fans: Compact models that connect directly to round ducts.
- Metal-housing centrifugal duct fans: For applications requiring high pressure in long duct runs.
- Plastic-housing duct fans: Lightweight and economical, for residential applications.
Values such as 100, 160, and 200 mm in product names indicate the duct diameter, while m³/h values indicate the flow rate.
Selection criteria
The duct fan diameter must match the diameter of the duct it will connect to. When selecting flow rate, duct length, number of elbows, and grilles must be taken into account; in long runs with many elbows, centrifugal (snail-type) duct fans generate higher pressure. If noise level is important, the fan can be placed in the middle of the duct run, away from the occupied area, and a silencer can be used. In systems where multiple rooms will be ventilated by a single fan, the total flow rate must be calculated correctly.
Installation and maintenance
The fan must be mounted firmly with clamps in the direction matching the airflow arrow on the housing. Flexible connectors can be used to prevent vibration from being transmitted to the duct. Having the fan in an accessible location will make future cleaning and replacement easier. In kitchen exhausts, cleaning intervals should be shorter due to grease buildup.
Frequently asked questions
What is the difference between a duct fan and a bathroom exhaust fan?
A bathroom exhaust fan is typically mounted on a wall or ceiling surface. A duct fan is placed inside the duct and can ventilate more than one point.
What if the duct diameter is different?
A connection can be made with suitable reducer fittings. However, reducing the diameter decreases the flow rate.
Does a duct fan make noise?
Fan noise diminishes along the duct. A silencer can be added for even quieter operation.
Can speed be controlled?
Speed control regulators can be used on suitable models.
Can it be used in a kitchen exhaust?
It can be used with models suitable for greasy air and regular cleaning.
How should the end opening to the outside be sealed?
It is recommended to fit a backdraft damper and a grille at the duct end.
