How do I create a negative pressure environment using HEPA Filtered Portable Air Scrubbers?
In order to create a negative pressure environment, more air must leave the space than enters it. First of all, the project area must be walled off with permanent or temporary construction barriers. Secondly, the Abatement Portable Air Scrubber(s) must be placed inside the construction area. Ductwork should be run from the system to somewhere outside of the project area, preferably to the outside of the building. Since the air is HEPA filtered, it is not mandatory to exhaust air to the outdoors.
