An 18v fan is available in different types depending on its application. The table below summarizes various types of 18V fans.
DC Axial 18V Fan
The 18V DC axial fan is designed to move air along the axis of its motor shaft. It consists of a propeller blade, frame, and motor. The rotor blades spin to draw in air and push out fresh air. DC axial 18V fans are common in electronic devices and laptops.
DC Brushless 18V Fan
It is a variant of the axial fan that lacks brushes in the motor. The absence of brushes reduces friction, resulting in more efficient fans. Moreover, the DC brushless 18V fan operates quietly compared to brushed variants. Also, it requires less maintenance and has a longer lifespan.
These fans are used in applications where noise must be minimized, such as in audio equipment, suburban areas, or during the night.
Radial 18V Fan
Radial 18V fans operate differently than axial fans. Instead of pushing air parallel to the motor shaft, they pull in warm air through the motor shaft and expel it perpendicular to the shaft. During this process, they compress the air, making them ideal for high-pressure applications. While some radial fans operate on DC power, others use AC power.
Radial 18V fans are installed in power supplies, HVAC systems, or turbines.
Centrifugal 18V Fans
Apart from the radial fans that compress air, centrifugal fans have a motor and impeller. The impeller blades rotate, pulling in fresh air and pushing it out with pressure. These 18V fans can function quietly or provide high airflow.
Centrifugal units are commonly found in dust extraction systems, industrial boilers, and fume extractors.
18V High-speed Turbo Fans
Turbo 18V fans are the fastest types available. They are designed to move high volumes of air. They come as axial or centrifugal turbo fans. Some manufacturers make them with brushless motors to reduce noise levels.
Battery :
The 18v battery fan is powered by an 18-volt lithium-ion battery. These batteries provide a consistent power source, enabling the fan to function without being plugged into an electrical outlet. Battery life can fluctuate between 4 and 10 hours, depending on the speed setting.
Motor :
DC motors, often known as brushless motors, are commonly utilized in battery-powered fans. They are more energy-efficient, releasing more power for the duration of the battery. DC motors for an 18v fan are usually three to four watt.
Fan Blades :
A battery-powered 18v fan typically has four to five plastic or metal blades. A greater number of fan blades may move more excellent air volumes. A typical blade length is about 8 to 10 inches, which is sufficiently compact to fit a battery-powered fan.
Speed Settings :
Depending on the model, an 18v battery fan may have two to three-speed settings. The low-speed option saves the battery life while providing a gentle breeze. The 18v fan can be used for various applications, depending on the speed.
Swivel Head :
Some 18v battery fans have a swivel head. It allows users to adjust the direction of air circulation. It usually has a pivot joint or ball joint mechanism that enables the fan to oscillate from side to side.
General care and maintenance can help prolong an 18v fan's lifespan while ensuring optimum performance. The rule of the gap is to clean it regularly, which is applicable to both indoor and outdoor 18v fans.
To clean the fan, use a damp cloth to wipe its body, including the battery compartment. Wipe it with soapy water to avoid water damage carefully. Use a vacuum cleaner to remove dust or debris from the inner section, but be sure to use it correctly to avoid damaging the motor.
Users should avoid using a high-pressure hose to wash the 18v fan, which may cause severe damage. Before storing the fan, ensure it is entirely dry to prevent mold growth or any damage.
It's crucial to keep the battery terminal clean. Users can use a small brush or cloth that's dry to clean off any debris or residue from the battery. Please don't use any liquid or chemical to clean the battery terminal.
Generally, the use of an 18v portable fan is dependent on the setting or environment. However, its versatility means that it can be used in any space where ventilation or cooling is desired.
Office and Workspace
In office and workspace settings, an 18v desk fan might be used to complement the buildings HVAC system by providing additional airflow and ensuring employees stay alert and focused by keeping them comfortable.
Indoor Areas
18v fans can be used in residential spaces like living rooms, bedrooms, kitchens, and bathrooms. They are useful in providing immediate relief when temperatures spike or in combating stuffiness or poor air quality.
Outdoor Areas
The portability of 18v fans makes them well suited for outdoor use. This includes activities like gardening or repairs as well as leisure activities like camping, picnic, hikes, or sporting events.
Travel and Transportation
18v fans can provide a comfortable journey by alleviating discomfort from heat or motionlessness in situations like long commutes, traffic jams or crowded public transport.
Emergency Situations
In times of crisis like natural disasters, power outages or medical emergencies, 18v fans can be a lifeline by preventing critical situations from worsening.
Blogging
Blogging is a popular added use of 18v fans. They are often used for a simple yet effective setup that provides a cool and comfortable environment for users to engage in their blogging activities.
Before purchasing the 18v fan, it is important to consider the following factors.
Battery life
The battery life of an 18v fan is an important consideration, as it determines how long the fan can run on a single battery charge. A longer battery life is preferable, as it allows for extended use without the need for frequent recharging. However, it is essential to balance this with the weight of the fan, as a larger battery for longer life may increase the fan's overall weight.
Portability
When considering the portability of an 18v fan, it's essential to look at factors such as weight, size, and handle design, which all play a crucial role in determining how easy the fan is to transport and move around. A lightweight construction makes it easier to carry for longer periods, while a compact design ensures it takes up less space and can be conveniently stored or transported. Additionally, a well-designed handle provides a comfortable grip and balance, making it easier to carry the fan to different locations.
Noise level
The operating noise level of the 18v fan should be considered. A quieter 18v fan can offer a more pleasant and peaceful user experience. However, a trade-off between noise levels and performance may exist, as higher airflow and speed ratings might produce more noise.
Speed settings
An 18v fan with different speed settings is a versatile option to adjust the airflow and noise level according to personal preferences and various situations. Choosing an 18v fan with multiple speed options will allow users to enjoy a customized cooling experience.
Price
When buying an 18v fan, it is necessary to consider pricing and budget constraints. Although it's important to find a fan that offers good value for money, balancing performance, features, and affordability is crucial. Ultimately, the decision should align with the intended use and required performance level.
Q1: Does 18V mean power?
A1: No, 18V does not mean power. 18V refers to the voltage of the fan. If the voltage varies, the speed and performance may change. However, it is essential to note that voltage does not necessarily equate to power.
Q2: How many hours does an 18V battery last?
A2: A fully charged 18V battery lasts for about 2 to 3 hours of continuous use. The actual runtime may vary depending on speed setting and condition.
Q3: Are 18V tools better than 12V?
A3: An 18V fan and other tools are better than a 12V in some situations. 18V tools are more powerful than 12V tools. However, 12V tools are more compact and lighter.
Q4: Can an 18V fan run on 20V?
A4: Yes, an 18V fan can run on 20V. However, it is not recommended.
