In Line Extractor Fans

In line extractor fans provide powerful and discreet ventilation by positioning the fan within the duct run rather than directly on the wall or ceiling. They are particularly useful for bathrooms, toilets, utility areas and other applications where effective air extraction is required over a ducted route.

In Line Extractor Fans for Effective Ducted Ventilation

In line extractor fans are installed within the ducting system, allowing the fan itself to be positioned away from the room being ventilated. This makes them a practical choice where strong extraction, flexible positioning and discreet installation are important.

Because the motor can be located within a ceiling void, loft space or another suitable part of the duct run, an inline extractor fan can also help reduce the level of fan noise heard directly within the room.

Where Are In Line Extractor Fans Used?

Inline fans are commonly used for ducted ventilation in bathrooms, toilets, utility rooms and other areas where stale or moisture-laden air needs to be extracted to an external termination.

They are particularly useful where the distance between the room and outside wall makes a conventional wall-mounted extractor fan less suitable, or where the installer wants the visible room vent separated from the fan motor.

Choosing the Right Inline Extractor Fan

The correct fan depends on the required airflow, duct diameter, total duct length and resistance created by bends, grilles and other components within the ventilation system.

When comparing models, consider:

  • Air extraction rate
  • Duct diameter
  • Length and layout of the duct run
  • Noise level
  • Timer or switching options
  • Humidity control where available
  • Installation location
  • Required environmental or IP rating

Duct Size and Airflow

Matching the fan to the correct duct size is important for efficient ventilation. Longer duct runs, multiple bends and restrictive external grilles can increase resistance and reduce airflow, so the complete ventilation route should be considered when selecting a fan.

Quieter and More Discreet Ventilation

One of the main advantages of an in line extractor fan is the ability to position the motor away from the occupied room. When installed correctly, this can provide effective extraction while reducing the amount of mechanical fan noise heard at the room vent.

Timer, Humidity and Switching Options

Depending on the model, inline extractor fans may be available with different control options including basic switching, run-on timers and humidity-based operation. Check the individual product specification to select the control method required for the installation.
