Bladeless fans are a recent invention, and as the name suggests, they do not have visible blades. Such fans create airflow within the enclosed base of the fan and then emit it from an oval or round head.
Bladeless fans are an innovative invention, but are bladeless fans really better? Bladeless fans are better as they have hidden blades in the base that makes them quieter and safer to operate. Furthermore, bladeless fans are based on air-multiplier technology and generate an impressive airflow in the room. Bladeless fans are also typically energy efficient as they work on a simple mechanism of sucking the air in and pushing it out, which allows them to consume less power.
Bladeless fans are better than regular fans in many aspects, but most people are unaware of their benefits. They mostly get them because they’re unique and unusual.
But what you really need to be looking for are their benefits and disadvantages, and how they’ll actually work in your own home.
Bladeless Fans: a Quick Overview
Bladeless fans or air multipliers are unique inventions with unusual characteristics. Such bladeless fans do not have visible blades, and the appearance of these devices is like a circular tube mounted on a pedestal.
Similarly, the mounted tube is only a few inches deep, and no one can expect that this device emits a cool breeze from the mounted circle.
Moreover, this device has no moving parts, but you can feel the air blowing through the tube after switching it on.
Here’s a quick one-minute video on how bladeless fans work:
But to go into more detail, there are a few scientific principles and an electronic elements that play an essential role in the working of bladeless fans.
The Unique Features of a Bladeless Fan
The following are the few unique features and benefits of a bladeless fan.
Technically, They Still Have Blades
Bladeless fans still have blades. Otherwise, how would they be called fans?
But those blades are hidden inside the unit and not visible. That’s why they’re called bladeless.
Air Multiplier Technology
You might be wondering, if the blades inside the bladeless fan don’t directly blow air into the room, how is this fan ever going to be powerful enough.
In fact, it’s the opposite. Bladeless fans are known to have increased air flow compared to a traditional fan.
The reason is air multiplier technology, and here are a few concepts behind it.
Entrainment of Air
Entrainment is simply an enhanced way of moving air by creating negative air pressure through friction. The process of entrainment starts when the surrounding air is drawn rapidly into the unit.
The airflow in the bladeless fans is stronger than the regular fans, as the entrainment created within it amplifies the air output up to 15 times compared to a regular fan.
Brushless Electric Motor
The bottom base of the fan contains a brushless electric motor.
This makes the fan more efficient, more powerful, and less noisy. The fan operates a bit more like a turbocharged airplane in this case. Rather than making rattling noises or giving out an inconsistent flow of air, you’ll notice it operates more smoothly, gives out a more even stream of air, and is quieter.
The reason it’s smoother is because it has 9 blades inside, rather than just a few clunky blades that a traditional fan has. This means more control of air and more smoothness.
When it comes to noise, this is typically a major complaint when it comes to traditional fans. But with some of the bladeless tabletop units, the noise can be almost negligible.
For example, the Sismel tabletop bladeless fan gives off 25 decibels (dB) of noise, which is even below what would be considered whisper technology.
Acceleration of Air
Bladeless fans make use of something called the coanda effect.
As the air continues to flow after getting inside and into the top ring, the air is pushed into a slit that pulls the air at an even more accelerated speed. This is why the air that comes out of the unit is far more forceful than the air that initially enters the unit.
In fact, the popular Dyson bladeless fan brand is touting to create airflow that’s up to 55 miles per hour!
Some Common Benefits of Bladeless Fans
Bladeless fans are a new trendsetter in the fan industry as they multiply the airflow and provide much better cooling.
But besides these cool features (no pun intended), they have many other advantages, as discussed below.
Less Energy Consumption
Bladeless fans consume less energy as they work on a simple mechanism of sucking the air in and troughing it out. This simple mechanism helps them to work in an energy-efficient way. Using the bladeless fans can be advantageous for you as you will not have to worry about the mounting cost of electricity every month.
Consistent Air Flow
Air multipliers generate consistent and steadier air as compared to the standard fans with blades. Moreover, as the fans do not have chunky rotating blades, you will not feel the inconsistent on and off airstream of an oscillating fan. Instead, you’ll feel a direct, consistent stream of air.
Bladeless fans work on air multiplying technology, draw a massive amount of air, and amplify it to a great extent. Moreover, they reduce the turbulence in the airflow and streamline the paths, creating a powerful and smooth jet of air.
The following are some other advantages of using bladeless fans.
- Bladeless fans are safe compared to the conventional ceiling and table fans as you will not fear cutting yourself with them.
- They’re also safer and easier to clean. No need to disassemble the wire cage first to get the dust off!
- Brushless motors last longer.
- You can adjust bladeless fans through the remote instead of changing their speed manually.
- Some have other features built in. For example, a bladeless fan may be both a cooling and heating fan, or it may have a built-in air purifier with HEPA filters.
Things to Consider While Buying Bladeless Fans
While buying bladeless fans, you should consider a few things.
Check the Noise of Bladeless Fans
A fantastic feature of bladeless fans is that they create less noise than the regular fans with blades. The reason is the design of the air multiplier. Therefore, while buying a bladeless fan, you should consider the level of noise it creates that you can tolerate. Since it’s a staple feature, make sure yours also has it!
Check the Energy Consumption
All bladeless fans consume less energy as their motor does not have to manage revolutions of large blades. Therefore, while buying a bladeless fan, ensure that it is energy efficient and lowers your electric bills compared to the conventional fans.
Check the Airflow and Specifications
Some people argue that the bladeless fans have low airflow as compared to the conventional fans.
Make sure you’re looking at the fan’s specifications. It may be as simple as the fan just being too small for the size of the room you’re trying to cool.
Consider Voice Control Fans and Other Tech Features
There are some bladeless fans available in the market that respond to voice controls and may integrate with apps. Buying a fan with voice control can be expensive, but it will be worth the money.
Check the Height Adjustment of the Fan
The height adjustment feature is outstanding, but it does not come in many models. Therefore, you should look for a fan that is convenient for height adjustment.
The reason for buying a fan with the features of adjustment is that it can control the fan’s position so that you can get maximum airflow.
Bladeless fans are an improved cooling method as compared to the traditional celling fans with blades.
They are lightweight, safe for a home with kids, and efficient in saving electricity. You can clean them quickly as their blades are hidden.
What’s not to love?
Is it worth buying a bladeless fan?
If you want to buy a device that can cool your place, you should consider bladeless fans. Buying a bladeless fan is an efficient investment that you can make. The reason is that they consume less electricity that can save you money. So you’ll have to weigh the pros of a lower electricity bill and a fan that’s likely to last longer versus the initial upfront cost.
Where should I place my bladeless fan?
You should consider two things. First is the direction of direct airflow. Second is how placing the fan at a particular place will be a safety hazard or not. After picking the area, place your fan in the direction of desired airflow and ensure that the fan’s cord is not a trip hazard.
