Particle-Removal System and Method

Abstract

The present invention includes a portable particle removal system that utilizes negative air pressure to remove particles from a room or other indoor space. The present invention also includes a method for utilizing said portable particle removal system

What is claimed is: 
     
         1 . A portable particle removal system comprising:
 a panel having at least two surfaces which are substantially parallel to each other;   at least one aperture through such panel and such surfaces; and   a fan which is installed in each such aperture and which is capable of directing air through such fan and through such surfaces.   
     
     
         2 . A portable particle removal system according to  claim 1  wherein such fan or fans are capable of operating at different speeds. 
     
     
         3 . A portable particle removal system according to  claim 1  wherein there are at least two apertures that have been installed through the panel and wherein a fan has been installed in each such aperture. 
     
     
         4 . A portable particle removal system according to  claim 1 , further comprising a device which attaches to the panel and which, in combination with the panel, fills or substantially fills a door or window opening; 
     
     
         5 . A portable particle removal system according to  claim 1 , further comprising a shroud which affixes over one facade of at least one such fan and which is capable of holding a removable filter. 
     
     
         6 . A portable particle removal system according to  claim 1 , further comprising an apparatus which affixes over one facade of at least one such fan and which is capable of attaching duct tubing to such portable particle removal system. 
     
     
         7 . A portable particle removal system according to  claim 6 , further comprising duct tubing and a second shroud which is capable of holding a removable filter. 
     
     
         8 . An attachment apparatus capable of attaching duct tubing to a portable particle removal system according to  claim 1 , the attachment apparatus comprising
 a means to be attached to such portable particle removal system,   an opening through the attachment apparatus which approximates the diameter of an opening in the duct tubing;   a collar which is capable of being attached to the duct tubing   
     
     
         9 . An attachment apparatus according to  claim 6 , further comprising a means to hold a filter. 
     
     
         10 . A method for removing particles from a room by placing a portable particle removal system according to  claim 1  in a door or window opening in such room and by using the fan or fans in such system to create negative air pressure in such room. 
     
     
         11 . A method for removing particles from a room or other indoor space, such method comprising:
 closing off such room or space with plastic sheeting,   creating an orifice in such plastic sheeting, such opening being approximately the size and shape of duct tubing,   connecting one end of duct tubing to the orifice in the plastic sheeting,   placing a portable particle removal system according to  claim 1  into a door or window opening which is not part of the room or space from which particles are to be removed,   connecting the other end of the duct tubing to the portable particle removal system according to  claim 1 , and   using the fan or fans in such system to create negative air pressure in the room or space from which particles are to be removed.
