Claim:
A portable air displacement system ( 100 ) for introducing or removing air from a zone, wherein said system ( 100 ) comprises: (a) a generally cylindrical fan housing ( 200 ) having a housing top side ( 210 ), a housing bottom side ( 220 ), a housing side wall ( 230 ), a housing anterior end ( 240 ), and a housing posterior end ( 250 ), wherein the fan housing ( 200 ) has a housing cavity ( 260 ) disposed therein fluidly connected to an exhaust aperture ( 300 ) disposed on the housing side wall ( 230 ) of the housing anterior end ( 240 ), wherein the fan housing ( 200 ) comprises a raised dome ( 400 ) disposed on the housing top side ( 210 ), wherein the raised dome ( 400 ) is fluidly connected to the housing cavity ( 260 ), wherein the raised dome ( 400 ) comprises a tapering dome posterior side terminating end ( 412 ) extending past the housing posterior end ( 250 ), wherein the raised dome ( 400 ) comprises a primary directional intake nozzle ( 310 ) disposed on the raised dome posterior side terminating end ( 412 ) and fluidly connected to the housing cavity ( 260 ), wherein the primary directional intake nozzle ( 310 ) is disposed opposed to the exhaust aperture ( 300 ), wherein the raised dome ( 400 ) comprises a plurality of secondary intake slots ( 320 ) radially disposed around an arc on a dome anterior side ( 420 ), a dome first side ( 430 ), and a dome second side ( 440 ), wherein the secondary intake slots ( 320 ) are not disposed on a dome posterior side ( 410 ), wherein the secondary intake slots ( 320 ) are fluidly connected to the housing cavity ( 260 ); (b) a centrifugal fan ( 500 ) disposed in the housing cavity ( 260 ) operatively connected to a power supply ( 510 ) and a power switch ( 520 ), wherein a transverse plane, Plane A ( 600 ), is disposed at a midpoint of the housing separating the housing top side ( 210 ) from the housing bottom side ( 220 ), wherein a centrifugal fan axis ( 502 ) is perpendicularly disposed with respect to Plane A ( 600 ); and (c) a positioning platform ( 700 ) having a generally planar first panel ( 710 ) and a generally planar second panel ( 720 ) offset from the first panel ( 710 ), wherein the positioning platform ( 700 ) is pivotally attached to housing posterior end ( 250 ) on a positioning platform posterior end ( 730 ), wherein the first panel ( 710 ) comprises a first panel outer periphery ( 712 ) generally shaped like a semi-ellipse with a first panel open center ( 714 ) also shaped like a semi-ellipse, wherein the second panel ( 720 ) comprises a second panel outer periphery ( 722 ) generally shaped like a semi-ellipse having a solid center, wherein the second panel outer periphery ( 722 ) is adapted to fit inside the first panel open center ( 714 ), wherein the first panel ( 710 ) is biased toward the second panel ( 720 ), wherein the first panel ( 710 ) and the second panel ( 720 ) are adapted to clasp a planar object on either side, wherein the positioning platform posterior end ( 730 ) is disposed opposed to the exhaust aperture ( 300 ).
