The Benefits of a Wingless Fan

What is a wingless fan? This type of fan is the same as a traditional bladed fan, except that it has no external blades. Instead, the fan has a pedestal with vanes that direct the airflow through a toroid and create a smooth, thin stream of air. The airflow is directed through the toroid and is very smooth, making it ideal for a variety of purposes, from quiet operation to maximizing energy efficiency.

Air Multiplier

The Air Multiplier for wingless fans uses clever aerodynamics and physics to produce more air for less energy. The fans’ base is adorned with small slits, allowing air to enter and exit freely. A brushless electric motor powers the tiny fan, which then shoots air into a hoop-like tube. The ring-shaped part of the fan shoots the air up and out.

The multiplication effect, also known as entrainment, allows the Dyson Air Multiplier to draw in 20 litres of air per second and pump it out at 300 litres. The resulting airflow is smooth and powerful enough to cool a small room or even an entire room. This effect is possible only because air is a gas, and it obeys the laws of fluid dynamics. This means that when air flows through a tube, it is drawn behind the fan and follows it. The air surrounding the edges of the fan will also flow in the direction of the breeze.

Coanda effect

The Coanda effect is a force that occurs when a fluid enters a curved surface and subsequently changes direction. For example, when a spoon is held by water, the surface slowly draws the liquid, slowing the layer in immediate contact and dragging other layers into the line of curved surface. The Coanda effect is one of the main forces behind the performance of many wingless airplanes, from the McDonnell Douglas YC-15 to the Boeing C-17 Globemaster III.

This effect is also present in conventional multi-copters. These aircraft contain a plurality of propellers, each providing lift, propulsion, and altitude control. The Coanda effect is the mechanism that causes the thrust from these aircraft. The proposed design combines the power of the Coanda effect with the benefits of a bladeless fan. It consists of a vertical inlet duct with an Electric Dusted Fan and a special nozzle ring. A pressure difference in the air due to the airfoil-like cross-section creates enough thrust to propel the aircraft.

Quiet operation

One of the benefits of the wingless fan is its quiet operation. The airflow is improved and the motor is less stressed. As the fan spins at low speed, it adds more air through a narrow slot in the center. Air flows out as a cylinder, adding more air through viscous shearing. The result is a smooth stream of air. Quiet operation of wingless fans is a boon for people who are sensitive to noise.


An energy-efficient wingless fan uses a brushless electric motor and nine asymmetrically aligned blades to circulate air. The frame of these fans is slightly sloped so that the air is drawn into the fan and amplified 15 times. This creates a powerful stream of air that pushes out air in two directions at once. The result is a constant, cool breeze in your home.

A wingless fan is a great option if your room is small and you don’t want to spend too much on electrical wiring. It uses a USB outlet to power its fan and provides two times as much circulation as a standard ceiling fan. You can even adjust the angle of the oscillation mechanism to get the exact angle you need. It also features a handle for easy movement and an included remote control.

Compact design

The compact design of a wingless fan is one of its primary advantages. It provides the cooling effect of a larger fan while being much smaller. Compared to conventional fans, wingless fans are easier to store, and their compact design allows them to be placed anywhere. The nozzles on a wingless fan are concentric to the interior passage 10. The motor is located inside a base 16.

The nozzle defines the opening that draws air from the external environment. This air flow is then directed over the Coanda surface. Its compact design makes manufacturing much easier and cheaper. A continuous interior passage also reduces noise and frictional losses. In addition to its compact design, wingless fans can be made into smaller sizes than traditional fans. However, the compactness of the design limits the number of available options. To overcome these challenges, wingless fans can be manufactured as one piece, which reduces the number of parts.
