Sojol's helical fan
“All motion is spiral. This is the archetypal shape of nature” According to naturalist Jay Harman, fans use 18% of the world’s electrical energy and their efficiency could be significantly improved by reconfiguring them according to the shapes of nature.
Test results for a unique helical fan/pump have shown improvements in performance, in particular volume and pressure, compared with standard centrifugal, axial and even mixed flow fans of similar dimensions. It has also shown improved noise level and power consumption. In addition, it’s size, shape and flow path offers more versatility in certain applications.
The helical fan was originally designed for the solar wall ventilator that posed restrictions on available space and shape, and needed to be very quiet with low power consumption.
A number of Sojol’s products, such as V1, V2 and the solar wall-integrated ventilator would not be effective without such a fan. Adequate filtration requires a fan capable of greater pressure than what is currently available on the market globally for the shape and size required in some applications.
This fan/pump belongs to an entirely new family. With tests so far showing that it can out-perform centrifugal, axial and even mixed flow fans, it is likely to be widely taken up in the future in many fields including in the renewable energy sector.
