Operating Principle:

bladeless fan works differently from conventional fans. The upper part of the fan is the ring, The lower part of the fan is cylindrical and has a variable speed control switch on it.
The bladeless ring works in a manner similar to aircraft wings. Actually, the fan does have blades; they are provided in the base of the fan. The air comes in towards a circular structure called a mixed flow impeller inside the cylindrical structure. The mixed flow impeller is actually an air pump, and it is used for blowing air upwards to the ring.

When the air reaches the ring, it creates a negative pressure above the joint of the ring and cylinder. This negative pressure forces the air that is present over the back side of the ring forward. Further, this creates a negative pressure at the back side of the ring, and due to this, air starts flowing from back to front, in what is called the Coanda effect. The air flows forward in a circular cross section. The air around the flow also starts moving due to viscous shearing, and the speed of the flow becomes sixteen times larger than that of any ordinary fan.

Advantages:

Safe for Children

This fan needs no exposed blades to provide air flow. Due to this, this fan is safe for children

Smooth Air

The air coming from an ordinary fan is not so smooth. It forces the air, by using blades, in the form of turbulent air slaps, which makes the air flow rougher. The bladeless fan is capable of flowing air very smoothly due to the absence of blades.

Fresh design

Designed with besutiful shape, and can be used for crafts furnishings,both practical and decorative.

Easy to clean

The structure of this fan is very simple, and because of this it’s very easy to clean.

Energy-saving

Its peak power is 40 watt.

Easy to operate

Adjust direction from all around, touch-key,very simple

the left is Motor with Hall element, especailly good in contorl stability, processing technic is difficult. the right isMotor without Hall element

The left is bearing produced by Japan NMB, branch office are around southeast Asia, USA, Germany etc.urbin. The right is not qulified bearing.

When the turbine generator is workinh, it turns very fast, so we must keep the balance of the weight all around. Some small company just use machinery equipment to cut(picture at the left), the structure of the turbinw will change, but we use Polymer Adhensive(picture right) to balance the weight, accuracy can be 0.001g.
