Attic ventilation system

Abstract

An apparatus to ventilate attic space of a structure such as a home or building is provided. The apparatus includes a flexible air sealer and a fan housing unit. The apparatus is connected to trusses or rafters of the structure. The apparatus is placed directly below a roof vent, with the air sealer creating a seal between the fan housing and the roof vent. The air sealer supports propeller fans located in the fan housing. The airflow caused by the fan directs air into the flexible air sealer, through the openings of the roof vent, and out of the attic space. The apparatus may further include adjustable truss connectors that are removably attached to the air sealer and the trusses to allow the apparatus to be installed between variably spaced rafters.

1 . A ventilation system for use with a structure having a roof with a roof vent, the ventilation system comprising: 
 an air sealer including first and second terminal ends, wherein said air sealer first terminal end is in fluid communication with said roof vent; and    a fan housing including a fan operable to generate a flow of air toward said roof vent, said fan housing coupled to said second terminal end;    wherein the ventilation system is operable to draw air from the structure into said air sealer and through said roof vent.    
   
   
       2 . The ventilation system according to  claim 1 , wherein said air sealer comprises flexible material.  
   
   
       3 . The ventilation system according to  claim 2 , wherein said roof is supported by trusses, and wherein said ventilation system further comprises adjustable connectors configured to secure said flexible air sealer to said trusses.  
   
   
       4 . The ventilation system according to  claim 3 , wherein said adjustable connectors may be repositioned along said flexible air sealer.  
   
   
       5 . The ventilation system according to  claim 2 , wherein said fan comprises a plurality of motor driven fans.  
   
   
       6 . The ventilation system according to  claim 2 , wherein said flexible air sealer comprises fabric.  
   
   
       7 . The ventilation system according to  claim 2 , wherein said fan is operatively coupled to a controller configured to engage and disengage said fan when a predetermined parameter is achieved.  
   
   
       8 . The ventilation system according to  claim 7 , wherein said controller includes one of a variable fan speed controller, a thermostat, and a humidistat.  
   
   
       9 . The ventilation system according to  claim 1 , wherein said air sealer comprises rigid material; and wherein said ventilation system further includes an extension configured slide into and out of said air sealer.  
   
   
       10 . The ventilation system according to  claim 9 , wherein said fan comprises a plurality of motor driven fans.  
   
   
       11 . The ventilation system according to  claim 9 , wherein said fan is operatively coupled to a controller configured to engage and disengage said fan when a predetermined parameter is achieved.  
   
   
       12 . The ventilation system according to  claim 11 , wherein said controller includes one of a variable fan speed controller, a thermostat, and a humidistat.  
   
   
       13 . The ventilation system according to  claim 9 , wherein said extension comprises flexible material operable to prevent air from escaping said ventilation system.  
   
   
       14 . A method of ventilating a structure having a roof with a roof vent, the method comprising: 
 providing a ventilation system comprising 
 an air sealer including first and second terminal end, and  
 a fan housing including a fan operable to generate a flow of air toward said roof vent, said fan housing coupled to said second terminal end;  
   positioning said air sealer first terminal end such that it is in fluid communication with said roof vent; and    activating said fan to draw air into said air sealer and through said roof vent.    
   
   
       15 . The method according to  claim 14  wherein: 
 said roof is supported by trusses;    said ventilation system further comprises adjustable connectors configured to secure said flexible air sealer to said trusses; and    said method further including connecting said adjustable connectors to said trusses.    
   
   
       16 . The method according to  claim 14 , wherein said ventilation system further includes an extension configured to slide into and out of said air sealer; and wherein said method further includes sliding said extension into said air sealer.  
   
   
       17 . The method according to  claim 14 , wherein said ventilation system further includes an extension configured to slide into and out of said air sealer; and wherein said method further includes sliding said extension out of said air sealer.
