This site is one of four locations where Hornwright Industrial set up air purifiers. In reality, they were not used to clean the air but instead were modified to serve as a tool to convert aerosolized minerals back into a solid form. The area is a good place for scavenging.
This small set-up includes a concrete building containing a tinker's workbench.
The Hornwright air purifier site #03 appears only in Fallout 76.
