Ducted Inline Extractor Fans

Everything You Need to Know About Inline Extractor Fans

Inline extractor fans are essential for maintaining proper ventilation in bathrooms, kitchens, and other spaces where moisture and odours can accumulate. They help ensure good air quality and prevent issues like mould growth and dampness.

This page will guide you through the different types of inline extractor fans, their benefits, and how to choose the best one for your needs.

What is an Inline Extractor Fan?

An inline extractor fan, also known as an inline exhaust fan, inline duct fan, or inline ducted extractor fan, is a ventilation device installed within the ducting rather than directly on the wall or ceiling. This setup allows for more flexible installation and typically results in quieter operation compared to traditional extractor fans.

Benefits of Inline Extractor Fans

1. Quiet Operation: Since the fan is installed within the ducting, usually in the attic, false ceiling, void or a separate room, it significantly reduces noise levels.
2. Flexible Installation: They can be installed in various locations, making them suitable for different room layouts and sizes.
3. Powerful Ventilation: Inline fans are often more powerful, providing better extraction rates, which is crucial for removing moisture and odours effectively.
4. Discreet Appearance: With the main unit hidden, only the ducting and grille are visible, maintaining a clean and uncluttered look.

Types of Inline Extractor Fans

• Inline Bathroom Extractor Fans: Specifically designed for bathrooms, these fans help manage humidity and prevent mould growth. Examples include the Blauberg Turbo and the Blauberg Iso-Mix.
• Inline Kitchen Exhaust Fans: These are more robust to handle grease and smoke from cooking. They ensure that your kitchen remains odour-free.
• Commercial Inline Extractor Fans: Designed for larger spaces like commercial kitchens or industrial settings, these fans handle high volumes of air and are built for continuous operation.
• Silent Inline Extractor Fans: Perfect for bedrooms or living areas where noise can be a disturbance. These fans, like the Blauberg Silent Vents and the Blauberg Bi-Turbo, operate at low decibel levels.

Inline Extractors with EC Fan Motors

Electronically Commutated (EC) fan motors represent a significant advancement in fan technology, offering several benefits over traditional AC motors:

• Energy Efficiency: EC motors are highly energy-efficient, consuming up to 50% less energy than AC motors. This efficiency helps reduce electricity costs and environmental impact.
• Variable Speed Control: EC motors offer precise speed control, allowing the fan to adjust its speed according to the ventilation requirements. This feature ensures optimal performance and energy usage.
• Longer Lifespan: Due to their advanced design and lower operating temperatures, EC motors tend to have a longer lifespan compared to AC motors.
• Quiet Operation: EC motors operate more quietly, making them ideal for residential and noise-sensitive commercial environments.
• Reduced Heat Generation: These motors generate less heat, contributing to a cooler operation and reducing the risk of overheating.

Popular models featuring EC fan motors include:

• Blauberg EC Turbo: Known for its exceptional energy efficiency and quiet operation, this fan is perfect for both residential and commercial applications.
• Blauberg Iso-Mix EC: Combines the benefits of mixed flow technology with the energy efficiency of EC motors, providing powerful yet efficient ventilation.

Purge Ventilation and Inline Extractor Fans

Purge ventilation is a concept introduced in modern building regulations aimed at maintaining good indoor air quality by effectively removing pollutants, moisture, and odours from indoor spaces. This type of ventilation involves the rapid and controlled expulsion of air from an interior space, ensuring that fresh air replaces the stale or contaminated air.

Building Regulation Requirements for Purge Ventilation

Recent updates to building regulations emphasise the importance of purge ventilation in residential and commercial properties. These regulations require that adequate ventilation systems are in place to ensure a healthy indoor environment. Inline extractor fans have emerged as a popular solution to meet these requirements due to their efficiency and flexibility.

Choosing the Best Inline Extractor Fan

When selecting an inline extractor fan, consider the following factors:

1. Extraction Rate: Measured in cubic metres per hour (m³/h) or cubic feet per minute (CFM), this indicates how much air the fan can move. For bathrooms, a fan with at least 100m³/h is recommended, whereas kitchens may require a higher rate.
2. Size: Ensure the fan size matches your ducting. Common sizes include 100mm, 150mm, and 200mm.
   Noise Level: Measured in decibels (dB), opt for fans that operate quietly if they are installed near living spaces.
3. Features: Look for additional features like built-in timers, humidity sensors, and variable speed controls, which can enhance functionality and convenience.

Installation Tips

• Location: Install the fan at a central point in the ducting system for optimal airflow. Avoid placing it too far from the area that needs ventilation.
• Ducting: Use smooth, rigid ducting to minimise airflow resistance and noise. Ensure that the ducting is correctly sealed to prevent leaks.
• Maintenance: Regularly check and clean the fan and ducting to ensure efficient operation. Dust and debris can reduce performance and increase noise levels.
