Can Abatement Portable Air Scrubbers also be used to filter and recirculate air or for positive pressure?
Definitely. Abatement PAS units can be used to continuously filter and recirculate 100% of the filtered air within the construction area. This will boost the ACH in the room and provide HEPA filtration, but will not change room pressurization. All models can also be configured to create positive pressure. See the continuous air cleansing and recirculation animation.
