Duct cover

Abstract

A temporary duct cover for use in an HVAC installation processes. The temporary duct cover having a filtration portion and a closure member. The filtration portion being made from material which is air and water permeable. The closure member being configured to conform a duct. The temporary duct cover minimizes particulate infiltration to the duct while allowing moisture to escape from the duct, thereby inhibiting mold or mildew from forming in the duct.

1 . An temporary duct cover for use in an HVAC installation processes, the temporary duct cover comprising:
 a filtration portion, the filtration portion made from material which is air and water permeable;   a closure member which is configured to conform to a duct;   wherein the temporary duct cover minimizes particulate infiltration to the duct while allowing moisture to escape from the duct, thereby inhibiting mold or mildew from forming in the duct.   
     
     
         2 . The temporary duct cover as recited in  claim 1 , wherein the filtration portion is made from spunbond polypropylene. 
     
     
         3 . The temporary duct cover as recited in  claim 1 , wherein the filtration portion is made from flash spun high-density polyethylene fibers. 
     
     
         4 . The temporary duct cover as recited in  claim 1 , wherein the filtration portion is made from bilaminate materials. 
     
     
         5 . The temporary duct cover as recited in  claim 1 , wherein the filtration portion is made from fabric which inhibits particulates larger than 100 microns from passing through the filtration portion and the temporary duct cover. 
     
     
         6 . The temporary duct cover as recited in  claim 5 , wherein the fabric inhibits particulates larger the 25 microns from passing through the filtration portion and the temporary duct cover. 
     
     
         7 . The temporary duct cover as recited in  claim 6 , wherein the fabric inhibits particulates larger the 10 microns from passing through the filtration portion and the temporary duct cover. 
     
     
         8 . The temporary duct cover as recited in  claim 7 , wherein the fabric inhibits particulates larger the 1 micron from passing through the filtration portion and the temporary duct cover. 
     
     
         9 . The temporary duct cover as recited in  claim 1 , wherein the closure member is made from elasticized hem. 
     
     
         10 . The temporary duct cover as recited in  claim 1 , wherein the closure member is made from a draw string. 
     
     
         11 . The temporary duct cover as recited in  claim 1 , wherein the closure member is made from a hook and loop closure. 
     
     
         12 . The temporary duct cover as recited in  claim 1 , wherein the filtration portion is made from fabric having values of greater than approximately 500 g of breathability. 
     
     
         13 . The temporary duct cover as recited in  claim 1 , wherein the filtration portion is made from fabric having values of less than approximately 20,000 mm of water resistance. 
     
     
         14 . A duct cover comprising:
 a filtration portion, the filtration portion made from material which restricts the ingress of particulates into a duct, retards the ingress of moisture into the duct and allows the egress of moisture from the duct to inhibit the formation of mold in the duct, the filtration portion having an open end and a closed end;   a closure member which is configured to conform to the duct, the closure member being provided at the open end of the filtration portion.   
     
     
         15 . The duct cover as recited in  claim 14 , wherein the filtration portion is made from spunbond polypropylene. 
     
     
         16 . The duct cover as recited in  claim 14 , wherein the filtration portion is made from flash spun high-density polyethylene fibers. 
     
     
         17 . The duct cover as recited in  claim 14 , wherein the filtration portion is made from bilaminate materials. 
     
     
         18 . The duct cover as recited in  claim 16 , wherein the closure member is made from an elasticized hem. 
     
     
         19 . A duct cover comprising:
 a filtration portion, the filtration portion made from material which inhibits particulates larger than 100 microns from passing through the filtration portion and the temporary duct cover, the material having values of greater than approximately 500 g of breathability and values of less than approximately 20,000 mm of water resistance.   
     
     
         20 . The duct cover as recited in  claim 20 , wherein a closure member is provided on the duct cover, the closure member is configured to conform to a duct, the closure member being provided at an open end of the filtration portion.
