Ventilation technology has a long history and has gradually developed alongside the changes brought about by the evolution of industries and buildings as well as changes in our personal needs.
The word ‘ventilation’ comes from the Latin ventilatio, in turn from ventus meaning wind, which was described in 1660 as a process to ‘replace poor air in an enclosed space with new and clean air’. It was also used early on to mean ‘breathing’, i.e. the exchange of oxygen and carbon dioxide in our lungs. The term was thus used to describe a process that was that was liberating, cleansing and necessary.
