What is the 18 ABS fan blades design in NAKKA?

As we all know NAKKA has the patented technology of 18 fan blades design.

The fan blades are made of ABS material and are divided into inner and outer layers. The outer layer has 11 blades and the inner layer has 7 blades. By the special design angle, the fan can operate to achieve the effect of a double spiral wind. The double spiral wind makes the air supply angle wider.

Fan blades are used in 18 inch floor fans with a large air supply angle up to 120° so that the air can spread to every inch in the room.

The 18 blades adopt silent technology, and the maximum noise level is only 56dB when used with an 18 inch commercial fan. It would not disturb your daily life and work.

It uses the unique design of double-layer 18 blades. The inner layer (7 blades) produces a rotating wind channel, and the outer layer (11 blades) produces a eight-shaped wind channel to spread the wind all around and farther. The wind cut by the 18 blades is very comfortable, so the fans keep making people comfortable in a long working condition that makes the true natural wind feeling.
