These four (4) Radata vapor intrusion mitigation systems (VMS) are installed internally at an 11-story, 300+ room Boutique Hotel in Manhattan, New York for indoor air quality. The four exhaust fans are located on the roof and there are special decals applied to the roof surface to designate a labeled exhaust safety area for contractors and maintenance staff. There are visual and audible alarms installed to alert maintenance staff should any of the four systems require attention. You can read more about Vapor Mitigation Systems here.
