exhale bladeless ceiling fanFans are a great way to keep any room cool without pushing your air conditioning system too hard. The main problem with regular fans is that the fan blades always get in the way regardless of whether you have a fan with a light or some means to remotely control the fan speed and operation.

This won’t be a bother anymore if you can land your hands on the best bladeless ceiling fan.

A bladeless ceiling fan isn’t noisy at all and since there are no moving parts, it is a safer gadget to have installed in your house. This coupled with the low-power motor and high efficiency means that the table, floor standing or ceiling fan uses more energy and is a perfect actualization of a fan with hidden blades dream.

How do Bladeless Fans Work?

This varies depending on the fan manufacturer. Since bladeless fans are a rather noble invention, each manufacturer is keen on patenting their technology. We are going to look at one approach used by Dyson to create their impressive range of bladeless table and floor standing fans before looking at Exhale who by now is the only kid in the block to design and sell a working bladeless ceiling fan.

Exhale Bladeless Fan Technology

Even though floor standing and table bladeless fans are common, getting a bladeless ceiling fan isn’t that easy. Actually, the only working contraption is the Exhale bladeless ceiling fan that uses the Tesla turbine principle. The Exhale fan uses a couple of spinning discs in a plastic enclosure to activate a calm vortex air flow.

Since the fan is silent and extremely energy efficient, you can keep it running on a 24/7 basis, giving an helping hand to your HVAC and keeping your utility bills at an all time low.

The idea behind this bladeless ceiling fan was to do away with the intruding presence of a traditional bladed ceiling fan. That overwhelming downwards push from the fan, the visible fan whir and the ever present noise that makes most people turn off their ceiling fans more often than they should.

Impressive Performance and Flexibility

With the fan clocking in at 40-43 dB when at full power (280 RPM) it is safe to say that this is perhaps the most silent fan you will ever have in your house. This coupled with the fact that the breeze created don’t rustle anything in the house to give you a cool and serene ambiance that would be perfect for daily activities or even sleeping especially if you haven’t invested in a smart bed fan.

Exhale noticed that their bladeless ceiling fan is a big installation that takes a huge chunk of your ceiling and has made it look as sleek as possible. It will belong to the ceiling, becoming more of a decoration than it is of a functional fan.

You can choose your fan’s color depending on your color scheme to ensure that it neatly falls into place once you install it.

 

Dyson’s Bladeless Fan Technology

Bladeless fan technology has been around for a while. Even though the original patent went to Toshiba back in 1981, it was Dyson who took the concept mainstream after adding a slight modification to make the airflow smoother. This not only ushered in a stream of commercial bladeless fans but also encouraged other manufacturers to come up with their own design.

Dyson prefers calling its bladeless fan an air multiplier since that is exactly what it does. A brushless electric motor with nine asymmetric blades pulls air into the unit before sending it through a tunnel and up a hollow tube. As air travels up the tube, it emerges through tiny slits around the frame edges of the hoop. This air flow leads to an induced air flow thanks to the physical law of inducement.

Another physics law, the law of entrainment, makes the air around the edges of the fan to begin flowing in the breeze’s direction. This will create a low-pressure zone in the hollow tube making it suck in more air that will add to the air taken in through the motor to create a stronger breeze.

You will get up to 15 times more air flow than what was sucked in by the motor meaning that Dyson’s technology, and other similar techniques, give you more air flow for less effort. The result? A safer, silent and energy efficient fan that is perhaps stronger than your daily blade fan.

Why Do You Need a Bladeless Ceiling Fan?

Bladeless Ceiling fans are a great alternative to the inherent problems that accompany traditional fans with blades. First of all, you won’t have that constant noise regular fans create while cutting through the air or the ruffle the resulting vortex impacts on the region below it. Your bladeless ceiling fan gives you a calm breeze similar to what you would get from big efficient windows hence keeping your room temperature homogeneous and the air fresh silently.

Couple this with the fact that no moving parts means that the fan is at home on low ceiling buildings and you never have to worry about getting your limbs caught and you have a smart and safe gadget for the cool home.

Exhale fans don’t focus on creating an unrealistic wind to keep you cool. They induce an almost natural air flow meaning that they can also be used during the cold weather to circulate warm air from your AC ducts or spot heater and give the entire room a warmer feel without forcing you to crank your AC a notch higher.

Up to date, Exhale seems to be the only one with a working bladeless ceiling fan. The majority of the brands in the market are using hidden or protected fan blade designs. This involves enclosing the fans in some kind of decorative cage to make them safer. This isn’t making them have all the bladeless ceiling fan benefits but they will be better. Air multipliers would be another alternative if you don’t mind placing your bladeless fan on the floor or on your table.
