Inline Extractor Fans
Inline extractor fans are a discreet yet powerful way to improve airflow and remove unwanted moisture and odours from enclosed spaces. Ideal for bathrooms, kitchens, utility rooms and commercial environments, these fans sit within your ducting usually in the loft or ceiling void, keeping the fan out of sight while maintaining strong performance.
At CM Electrical, our inline extractor fans are reliable, designed to suit both domestic and commercial applications. Whether you're after a high-power system for a busy household or a quiet model for a more subtle installation, we have options to suit every requirement.
Why Choose an Inline Extractor Fan?
Inline fans are especially useful where wall or window-mounted fans aren't practical, or where a neater finish is desired. These fans are usually connected to ducting that runs from the extraction point (such as a bathroom ceiling) to an external vent, making them ideal for rooms without direct external walls.
They also tend to be more powerful than standard axial fans and can extract air over longer distances. This makes them perfect for larger bathrooms, multi-room systems or where the extraction point is far from the exterior wall or roof vent.
Key Features to Look For
Airflow Capacity: Choose a fan with the correct airflow rating (measured in m³/h) based on room size.
Noise Level: Inline fans are usually quieter since they’re mounted away from the living space.
Timer or Humidistat Control: Some models feature built-in sensors for automatic operation.
Ducting Size Compatibility: Available for 100mm, 125mm, 150mm and larger ducting setups.
Ease of Maintenance: Many fans feature removable impellers or covers for easier cleaning.
FAQs
What is an inline extractor fan?
An inline extractor fan is a ventilation unit installed within ducting—typically in a loft or ceiling void, rather than directly on a wall or window. It draws air from a room through ducting and vents it outside, offering a discreet and efficient way to manage moisture, odours and stale air.
Where should I install an inline extractor fan?
Inline fans are ideal for bathrooms, utility rooms, kitchens and commercial spaces. They're especially useful where direct external wall access isn’t available, or when a quieter, hidden system is preferred. They are usually mounted in a loft or ceiling cavity, connected to ducting between the room and the external vent.
Are inline fans better than standard extractor fans?
Inline fans can offer higher airflow performance and quieter operation, particularly in large or high-moisture areas. Because they’re installed away from the room, they’re less noisy than wall or ceiling-mounted axial fans. They’re also more versatile in ducted systems that span long distances.
Do inline extractor fans need to be vented outside?
Yes, all extractor fans including inline models, must vent the extracted air to an external outlet. This ensures that moisture and odours are properly removed from your property, preventing mould, damp and other indoor air quality issues.
Can I install an inline extractor fan myself?
While some experienced DIYers may choose to install inline fans themselves, it’s generally recommended to have a qualified electrician or installer handle the job. Proper installation is essential for safety, especially if the fan is connected to bathroom electronics or integrated with lighting.
Do I need a timer or humidity sensor with my inline fan?
Timer and humidity sensors improve efficiency by running the fan only when needed. Timers allow the fan to run for a set period after the light is switched off, while humidistats activate the fan when moisture levels rise, ideal for bathrooms or wet areas.
