Extractor fans come in two main types: axial and centrifugal. Axial fans efficiently push large air volumes in settings with low-pressure needs, like warehouses and HVAC systems. Simple maintenance and cost-effectiveness make them popular. In contrast, centrifugal fans excel in moving air through complex ductwork and handling higher pressures, perfect for industrial spaces and commercial kitchens. They use a spinning impeller for right-angle air expulsion. Understanding each fan type's capabilities helps make informed choices. Discover more about their specific applications now.
Key Takeaways
- The two types of extractor fans are axial and centrifugal.
- Axial extractor fans efficiently move large air volumes with rotating blades.
- Centrifugal extractor fans use a spinning impeller for strong airflow in complex ductwork.
- Axial fans are ideal for high airflow and low-pressure applications.
- Centrifugal fans are suitable for high-pressure needs and longer ductwork.
Understanding Axial Extractor Fans
Axial extractor fans move large volumes of air efficiently. Their blades rotate like an airplane propeller, pushing air directly.
They're ideal for high airflow settings like warehouses and factories. Simple design means low cost and easy maintenance.
Common in HVAC systems, cooling towers, and wind tunnels.
Features of Axial Extractor Fans
Axial extractor fans efficiently handle high airflow with airplane-like blades. They push air directly, useful for moving large air volumes.
Simple design includes motor, blades, casing; easy maintenance, cost-effective. High RPM boosts airflow.
Varied sizes fit tight spaces, energy-efficient, quiet operation.
Ideal Applications for Axial Extractor Fans
Axial extractor fans work well for high airflow needs in places like factories and kitchens. They move air parallel to the fan's axis, expelling fumes and regulating temperature.
Simple to install, they're cost-effective for large spaces.
Axial fans enhance air quality in factories by removing dust and fumes. In warehouses, they maintain temperature to prevent heat buildup.
Commercial kitchens use them to clear heat and odors. Their straightforward design allows for easy installation and maintenance.
Choosing the right fan size and capacity is crucial to meet specific needs.
Exploring Centrifugal Extractor Fans
Centrifugal extractor fans create strong airflow and handle complex ductwork. They use a spinning impeller to pull air in and push it out sideways. These fans handle different air temperatures and moisture levels. They're found in kitchens, factories, and labs.
Centrifugal fans are bigger than axial fans but offer better pressure and efficiency. Different blade designs affect performance: backward-curved blades save energy, while forward-curved blades increase air volume.
They're suitable for places needing high pressure and adaptability.
Features of Centrifugal Extractor Fans
Centrifugal extractor fans are sturdy and efficient, ideal for duct systems with high static pressure.
They move air against resistance with powerful motors and backward-curved blades.
They're quieter than axial fans and energy-efficient, requiring less maintenance.
Available in various sizes.
Ideal Applications for Centrifugal Extractor Fans
Centrifugal extractor fans are ideal for moving air in places with complex ductwork.
They work well in commercial kitchens, labs, and factories where it's important to remove smoke, odors, and fumes.
- Commercial Kitchens: Remove smoke and smells even with complex ducts.
- Laboratories: Extract chemical fumes for a safer air environment.
- Industrial Settings: Keep air quality good in large spaces with complex ducts.
Comparing Axial and Centrifugal Extractor Fans
Axial fans offer high airflow for low-pressure needs, ideal for short distances like home or small office use.
Centrifugal fans handle high pressure for long ductwork, suitable for industrial settings or commercial kitchens.
Choose based on airflow and pressure.

How Do I Maintain an Extractor Fan for Optimal Performance?
Clean the extractor fan regularly, check for blockages, and ensure the motor functions properly.
Dust buildup can reduce efficiency, so clean the blades and grill every few months.
Ensure there's no obstruction in the ductwork, which could hinder airflow.
Inspect the motor by listening for unusual noises indicating wear.
Use a vacuum or air blower for dust removal.
Replace filters if applicable.
Regular checks ensure your extractor fan maintains optimal performance.
What Are the Energy Efficiency Ratings for Extractor Fans?
Extractor fans usually have energy ratings from A++ to D.
Look for models with an A++ rating for optimal efficiency. Check the fan's wattage, airflow rate, and noise level to determine the best fit for your needs.
High-efficiency models save energy but might cost more upfront. Compare brands like Vent-Axia and Manrose for different features and prices.
Choose a fan with a timer or humidity sensor for even greater energy savings.
Are There Smart Extractor Fans With Remote Control Capabilities?
Yes, there are smart extractor fans with remote control capabilities.
These fans offer features like app-based control, voice activation, and integration with smart home systems. You can adjust settings remotely using your smartphone, enhancing convenience.
Look for models with energy-efficient ratings (like ENERGY STAR) to save on electricity.
Smart fans often include sensors for humidity and air quality, providing automated adjustments.
Brands like Panasonic and Broan offer popular options with advanced tech features.
What Noise Levels Are Typical for Extractor Fans?
Typical noise levels for extractor fans range from 20 to 40 decibels for quieter models, while louder ones can reach up to 70 decibels.
When choosing an extractor fan, consider if you need a low-noise model, especially for areas like bedrooms or offices.
Fans with brushless motors often operate more quietly.
Check for sound ratings in product descriptions.
Compare brands like Panasonic or Broan, which offer models specifically designed for quiet operation.
Can Extractor Fans Be Installed DIY, or Is Professional Help Needed?
You can install extractor fans yourself, but it depends on your skills and the complexity of the installation.
Basic wall-mounted fans might be a manageable DIY project with some tools and instructions.
However, if you're dealing with ductwork, electrical connections, or ceiling-mounted models, professional help ensures safety and compliance with local building codes.
Inadequate installation can reduce efficiency and increase noise levels.
Always use a voltage tester when dealing with electrical components.
Wrapping Up
Axial and centrifugal extractor fans each have their perks. Axial fans are great for spaces like bathrooms and kitchens where you need lots of airflow with low pressure. Centrifugal fans shine in more challenging setups, like ducted systems or commercial spaces. Go with an axial fan for easy installation and energy savings. If you need high power for complex systems, a centrifugal fan is your go-to. Think about what you need most when picking your fan.
