Abstract
A portable environmental clean air frame facility including a power unit section and a clean air section. The frame is formed by P.V.C. pipes and fittings so that clear plastic sheeting material may be formed and draped over the clean air section to form a clean air enclosure. The power unit section includes a blower motor having a prefilter unit on each end. One end draws air from the surrounding medium and one is connected to the clean air enclosure. The prefiltered air is directed through a HEPA filter, through an air delivery duct and into the enclosure. A bypass damper is provided for controlling the air flow velocity and for producing either a positive or negative pressue in the enclosure.
