The invention relates to a public health protection system characterised by the conversion of indoor spaces into negative pressurization chambers and the synchronical decontamination of the inside air thereof. The herein developed system enables thecreation of chambers with use and adaptation of marketed devices respecting the WHO specifications and ensuring the direct air decontamination as well as the retention of air-transported microorganisms. Subjected to negative pressurization surpassing the 25 Pa and to consecutive air renewals (12 times at least), the thus created chambers (rooms, vehicles or other indoor spaces) attain the purification of the air exhausted from their indoor space by 99.9% and, in parallel, the reduction (up to 99%) of the microbial load of same indoor space. Each system allows the adaptation of two devices inside each closed space. The subsidiary constituent parts of the invention are the following: 1) arrangement connecting the one device to the ambient space (fig.3); 2) incorporated safety arrangements, and air input arrangement with servomechanisms for the automatic regulation of the pressurization into the chamber (fig. 4). The subsidiary parts constitute, as a whole, the base for the creation of products leading to standardized processes and the technical conversion of whatever typical room into negative pressurization chamber with parallel optional purification of the inside air of this last. |
