Hey there! As an air extractor supplier, I get asked a lot about how to reduce the noise of these machines. It's a common concern, especially when the air extractor is installed in a place where quietness matters, like a bedroom or a study. In this blog post, I'll share some practical tips and tricks to help you cut down on that annoying noise.
First off, let's understand why air extractors make noise in the first place. There are several factors at play. One of the main causes is the motor. When the motor runs, it generates vibrations, and these vibrations are transferred to the housing of the extractor, creating noise. Another source of noise is the airflow. As air is sucked in and pushed out, it can create a whistling or whooshing sound, especially if the airflow is turbulent.
Now, let's get into the solutions.
1. Choose the Right Location
The location where you install your Air Extractor can have a big impact on the noise level. Try to mount it on a solid surface. If it's attached to a flimsy wall or a surface that vibrates easily, the vibrations from the motor will be amplified, making the noise worse. For example, if you're installing it in a kitchen, mount it on a sturdy cabinet or a solid wall.
Also, keep it away from areas where people spend a lot of time. If possible, install it in a utility room or a less - frequented part of the house. This way, even if it does make some noise, it won't be as disruptive.
2. Use Anti - Vibration Mounts
Anti - vibration mounts are a great way to reduce the noise caused by motor vibrations. These mounts are usually made of rubber or other soft materials that absorb the vibrations before they can be transferred to the surrounding structure. You can easily find these mounts at hardware stores or online. Simply attach them between the air extractor and the mounting surface. They're pretty easy to install, and they can make a noticeable difference in the noise level.
3. Check the Fan Blades
Over time, the fan blades of your air extractor can get dirty or damaged. If there's dirt or debris on the blades, it can cause an imbalance, which in turn leads to more noise. Regularly clean the fan blades with a soft brush or a cloth. If you notice any signs of damage, such as cracks or chips, it's best to replace the blades. A balanced set of fan blades will run more smoothly and quietly.
4. Upgrade to a Quieter Model
If you've tried all the above methods and the noise is still a problem, it might be time to consider upgrading to a quieter model. When shopping for a new air extractor, look for models that are specifically designed to be quiet. Some manufacturers use advanced technology to reduce noise, such as special motor designs or aerodynamic fan blades. You can also check the product reviews online to see what other users have to say about the noise level of different models. Our Kitchen Ventilation Duct Fans are known for their quiet operation, so be sure to take a look at them.
5. Seal the Ductwork
Leaky ductwork can cause a lot of noise. When air leaks out of the ducts, it creates a whistling sound. Inspect the ductwork connected to your air extractor and look for any gaps or holes. Use duct tape or a sealant to close these gaps. This not only reduces noise but also improves the efficiency of your air extractor by preventing air from escaping.
6. Install a Silencer
A silencer is a device that can be installed in the ductwork to reduce the noise of the airflow. It works by absorbing the sound waves and reducing their intensity. There are different types of silencers available, such as straight - through silencers and baffle silencers. You can choose the one that suits your needs and the layout of your ductwork. They're relatively easy to install, and they can significantly reduce the noise coming from the air extractor.
7. Maintain Your Air Extractor Regularly
Regular maintenance is key to keeping your air extractor running quietly. Besides cleaning the fan blades, also check the motor for any signs of wear and tear. Lubricate the moving parts if necessary. A well - maintained air extractor will not only be quieter but also last longer.
In conclusion, reducing the noise of your air extractor is definitely achievable. By following these tips, you can enjoy a quieter and more comfortable environment.
