Abstract:
1. Apparatus for transforming the air exchange load of a higher air exchange rate space in a building into the air exchange load of a lower air exchange rate space in a building, said apparatus comprising: a housing for mounting to a surface of the higher air exchange rate space in the building; an air inlet formed in said housing; at least one air outlet formed in said housing; a passageway extending through said housing and connecting said air inlet to said at least one air outlet; a circulation fan disposed in said passageway so as to draw the ambient air of the higher air exchange rate space into said air inlet, through said passageway, and return that air to the higher air exchange rate space through said at least one air outlet; and a filter disposed in said passageway for purging non-particulate hazardous chemicals from the ambient air passing through said passageway, whereby to transform the air exchange load of the higher air exchange rate space into the air exchange load of a lower air exchange rate space.
