BEIJING: Who says construction can’t be clean or stylish? A giant inflatable dome has been erected over a construction site in eastern China, in what may be the country’s puffiest solution yet to keeping dust and noise pollution down.

According to Times Now News – an English-language news outlet based in India – which reported on the project on July 3, the dome is the first of its kind in China and uses negative pressure and air filtration systems to prevent dust from escaping into nearby areas.

negative pressure

I'm gonna guess that the dome itself is more like a pool floaty, as in there's an air gap between the outside wall and the inside wall which is inflated to give it structure. Then, the air under the dome is pumped out with fresh air pumped in at a rate that creates a negative pressure under the dome.

That must be a lot harder than a regular inflated dome. Impressive that it works
