Fan history and development
Like many other inventions destined over time to become tools of common and mass use over time,the fan originates for purely industrial purposes.
Its appearance is in fact due to Omar-Rajeen Jumala, who in 1832 built the first mechanical fan in history. Its first applications were, in fact, industrial. Some factories were coal mines that benefited from this tool which allowed them to optimize work in these fields.
Certainly, ventilation systems had already appeared on earth many years earlier. It dates back to around 500 BC. the first ventilation system, called diPunkah, used in India of the time to defeat the heat and cheer the aristocrats of the time.
However, making it the ancestor of the modern fan remains a risky operation. His system was, in fact, entirely manual. “Specialized” servants (called Punkawallah in reference to their activity) operated a large fan made up of large leaves called Palmyra, simply by pulling ropes connected to it.
To see the first fan for domestic use and marketed en masse, we will have to wait until 1882, when the young American Schuyler Skaats Wheeler, aged only 22, developed the first electric fan destined to enter homes throughout America.
The invention led to a rapid development of this instrument, which began to be built in different versions. The first ceiling fan was created by Philip Diehl and shortly afterwards fans capable of emitting hot air, powered with oil, alcohol or kerosene, were also completed.
Certainly, unsafe instruments remained. The first fans with rotating blades were practically devoid of functional cages as we can see today. It was not difficult for the brass blades to injure inexperienced young people who dared to get too close to the instrument.
Diffusion of electric fans and first air conditioners
In the 1920s, the decisive change of pace took place which led to the enormous spread of an infinite number of household appliances, including fans.
The industry of the time, in fact, began to work on a large scale steel, a material with which it was then possible to build all the electronic devices destined to enter the homes of millions and millions of families.
The Thirties saw the definitive explosion of the sector. The processing of steel has made great strides and has allowed the creation of appliances of all shapes and colors, increasing the commercial appeal of the latter.
The creation of the first stylized fan, the famous Swan Fan, was due to this period, which, spread in different shapes and colors, occupied a stable role in the furnishing of the house of the time.
From 1960 onwards, however, many fan companies had to close or convert due to the increasingly massive use of centralized heating systems, capable of also producing hot air and therefore more functional.
Fans still remain the most used tools for cooling industrial machinery and there are a great variety of them, which can be classified into 3 macro categories: Axial, Tangential and Centrifugal Fans, clearly endowed with different characteristics.
