Heavy-duty extractor fans are large ventilation devices used to eliminate unpleasant odors, smoke, and humidity and let fresh air enter a space. They create a negative pressure zone in addition to removing the items mentioned from a room. In contrast to standard extractor fans, heavy-duty ones can handle a higher volume of air and are appropriate for larger facilities and industrial settings.
Centrifugal extractor fans
Indoor and industrial heavy-duty extractor fans with a centrifugal design comprise an impeller, a housing unit, an electric motor, and some mounting elements. They let fresh air into a space by using centrifugal force to move air from the inlet side through the housing unit to the discharge side, eliminating air from a space.
Axial heavy-duty extractor fans
Heavy-duty axial extractor fans are generally made up of an impeller, a motor, a housing unit, and some mounting elements. They work by allowing the air to flow through the blades perpendicularly. They then push the air out horizontally. In places that require the ventilation of a high volume of air at a low pressure, they are suitable for use.
Mixed flow heavy-duty extractor fans
In places that require the ventilation of a high volume of air at a low pressure, they are suitable for use. The housing unit of a mixed-flow heavy-duty extractor fan is comprised of a motor, an impeller, and some mounting elements. While the motor rotates the impeller, which moves the air, the other components support and protect the fan. Compared with other types of extractor fans, mixed-flow extractor fans have the advantage of high-pressure, high-efficiency, and low-noise operations.
bladeless heavy-duty extractor fan
Functions without a visible rotating blade, the impeller of a bladeless fan sits within the base. The lower part sucks the air in, and the enclosed motor then pushes the air out, creating a subtle movement of air that resembles to airflow of regular extractor fans, removing heat and humidity from a space.
Heavy-duty extractor fans have different specifications based on the intended applications and designs. The size of the extractor fan is often represented by the blade diameter in inches or millimeters. They can range from small domestic fans, about 6 to 12 inches, to larger industrial or commercial ones that are more than 12 inches in diameter. The RPMs of heavy-duty extractor fans are also considered. RPM indicates how fast the blades of the fan rotate in a minute. Higher RPM means that the fan can move a larger volume of air. The extractor fan speed is usually three or four and can range from low, medium, and high to a very high level. Some heavy extractor fans have a 3-speed setting that allows users to customize the ventilation and noise level.
Another specification to consider is the noise level produced by heavy-duty extractor fans. Fans are designed to operate at a certain level of noise which is measured in decibels (dB). Some fans’ noise level is high and may not be ideal for use in the home. The airflow rating is also another specification to consider. The airflow of an extractor fan is usually measured in cubic feet per minute (CFM). The higher the CFM, the more air the fan moves. Heavy-duty extractor fans are designed to move a higher volume of air, and their CFM can range from 500 up to several thousands.
Fan blades and casing need to be cleaned regularly to keep the fans operating as needed and to prevent dust and debris from circulating in the air. Start the maintenance process by turning OFF the power supply to the fan. Next, users should remove the fan from its mounted position or, in some cases, remove the protective grill only. They should use a vacuum cleaner with a brush attachment to clean or remove the dust from the blades. While using a vacuum cleaner makes the process easier and cleaner, it's more preferable to wash the blades with soap and water later. A damp towel or sponge can be used to clean the underside of the fan blades and grill. A mild detergent solution can be used to damp the towel when cleaning the blades. If the fan is rather old and full of grime, clean it with degreaser and water. Once the surfaces are clean, ensure that the moisture is dried completely before powering the fan ON.
Heavy duty extractor fans are used in various industries to remove unwanted fumes and maintain a consistent flow of fresh air. Here are some common usage scenarios for heavy-duty extractor fans:
Factories and manufacturing sites
Heavy-duty extractor fans are commonly mounted on the roof of factories and other manufacturing sites, such as workshops. They are used to remove hazardous fumes, gasses, and particles generated by specific machinery and processes. This helps in ensuring the safety and comfort of workers within the manufacturing site.
Food processing
In the food-processing industry, heavy-duty extractor fans can be used for various purposes. They may be used for removing humidity from a specific room or for managing unwanted smells. Heavy-duty extractor fans help in enhancing the quality and safety of the food processed.
Commercial kitchens
Heavy-duty extractor fans are essential parts of commercial kitchen ventilation systems. They help in removing smoke, heat, moisture, and cooking odors from the kitchen. Installing heavy-duty extractor fans helps in ensuring a safer cooking environment, preventing grease buildup, and maintaining air quality.
Car repair and service centers
Heavy-duty extractor fans may be used in service and car repair centers to provide a more convenient and comfortable environment for both staff and customers. The fans keep the center well-ventilated by extracting harmful substances that can be generated during car repairs, such as exhaust fumes and chemical odors.
When stock heavy-duty extractor fanets, it is essential to consider a range of factors to ensure the product will meet customers' needs. First, the power of the extractor fan is an essential consideration. Customers will typically go for extractor fans with powerful motors to provide efficient air/ moisture/ fume/ gas/ dust extraction and ventilation, especially in industrial or commercial settings where they are used to handle high volumes of airflow.
The airflow of the extractor fan is also an essential consideration when stocking up. Choose fans with a high CFM rating, as this indicates the volume of air the fan can move. Consider stocking up on different fan sizes so customers can select one that meets their specific airflow requirements. Consider the operating noise level of the extractor fan when stocking up. Customers will typically go for fans with low noise levels, especially for use in residential or commercial settings where noise pollution might be an issue. Consider stocking up on units with different noise ratings (decibels).
Consider the build material of an extractor fan when stocking up. Ideally, customers will go for units with sturdy materials for longevity and durability. Also, consider the fan's design. During the stocking process, it might be best to include different fan designs, as this will help customers looking for extractor fans that match their space decor or one that fits into their ceilings, walls, or windows.
When stocking an extractor fan, it's crucial to consider the installation process. Ideally, customers will go for easy-to-install units. Also, consider the size of the extractor fan. It's a good idea to include different sizes as this will allow customers to select the ones that suit their spaces or needs. Additionally, considering the type of extractor fan (traditional, inline, ducted, or centrifugal) when stocking up is essential, as different customers have different preferences.
Heavy-duty extractor fans run on electricity most of the time. However, some models use solar power. It is, therefore, important to consider the power source of the extractor fan during the stock-up. Because some customers typically prefer battery-powered units as they are more convenient and portable.
Q: Does an extractor fan have to be heavy duty for domestic use?
A: Not necessarily. A standard duty extractor fan would suffice in most domestic settings. However, heavy duty extractor fans are designed to operate at a higher extraction rate and cope with high volumes of steam and air. This makes them suitable for use in large residential properties or commercial settings where a high ventilation rate is required.
Q: How loud are heavy duty extractor fans?
A: The noise level of a fan is measured in decibels (dB). Most heavy duty extractor fans range between 56 and 69 dB. They are roughly the same as a normal conversation or the sound of a dishwasher. The more powerful the fan, the higher the decibel level. While some commercial or industrial settings may require such a powerful extractor fan, the noise level would probably be too high for use in a domestic setting.
Q: How long can a heavy duty extractor fan run continuously?
A: Generally, users can run an extractor fan continuously for about 10 years or more, provided it is well maintained. However, to be on the safe side, it is best to turn the extractor fan off after 10 hours of continuous use. If the extractor fan is to be used in a high-risk room such as the bathroom or kitchen, it may be best to install a heavy duty fan rated for continuous use.
Q: Does a heavy duty extractor fan consume a lot of electricity?
A: The power consumption of an extractor fan is measured in watts. Heavy duty extractor fans generally use more power than standard duty fans due to their large motors. Tests showed that the power consumption of a heavy duty extractor fan ranged from 44 to 55 watts. That’s roughly the same as running a ceiling fan. Some centrifugal extractor fans with highly efficient motors may use as little as 20 watts. The fan's power rating will determine how much electricity it uses per hour. A 100 watt extractor fan will use 0.1 kilowatt hours (kWh) of electricity every hour. It will consume roughly 2.4 kWh if it runs for 24 hours every day for a month, which translates to about $0.24.
