Ventilation system and method

Abstract

A ventilation fan is disclosed having a housing with at least one sidewall defining an interior space, an inlet opening into the interior space, and an outlet aperture spaced apart from the inlet. The housing has at least one of a prong and a recess with at least one nail extending away from the at least one of a prong and a recess toward an aperture in the housing. The at least one of a prong and a recess is configured to be deformable to allow the at least one nail to pass through the aperture in the housing.

1 . A ventilation fan comprising:
 a housing having at least one sidewall defining an interior space, an inlet opening into the interior space, and an outlet aperture spaced apart from the inlet, wherein the housing is configured to contain a blower assembly in the interior space;   at least one of a prong and a recess having at least one nail extending away from the at least one of a prong and a recess toward an aperture in the housing;   wherein the at least one of a prong and a recess is configured to be deformable to allow the at least one nail to pass through the aperture in the housing.   
     
     
         2 . The ventilation fan of  claim 1 , wherein the housing further comprises at least one mounting flange extending from any exterior of the fan housing and the mounting flange comprising the at least one of a prong and a recess. 
     
     
         3 . The ventilation fan of  claim 1 , wherein the at least one of a prong and a recess is a prong having an arm extending from the housing and at least one nail extending from the arm. 
     
     
         4 . The ventilation fan of  claim 1 , wherein the at least one nail is three nails. 
     
     
         5 . The ventilation fan of  claim 1 , wherein the at least one nail is aligned perpendicular to the housing. 
     
     
         6 . The ventilation fan of  claim 1 , wherein the nail defines a triangular shape. 
     
     
         7 . The ventilation fan of  claim 1 , wherein the nail defines a triangular shape and a first ear extend from the triangular shape. 
     
     
         8 . The ventilation fan of  claim 1 , wherein the at least one of a prong and a recess is a prong and the prong comprises:
 a nail head defining a nail head aperture, and   the nail defines a nail shank extending from the perimeter of the nail head aperture.   
     
     
         9 . A ventilation fan housing configured to house a blower, the ventilation fan housing comprising:
 at least one sidewall defining an interior space, an inlet opening into the interior space, and an outlet aperture spaced apart from the inlet;   at least one of a prong and a recess having at least one nail extending away from the at least one of a prong and a recess toward an aperture in the housing;   wherein the at least one of a prong and a recess is configured to be deformable to allow the at least one nail to pass through the aperture in the housing.   
     
     
         10 . The ventilation fan housing of  claim 9 , wherein the housing further comprises at least one mounting flange extending from any exterior of the fan housing and the mounting flange comprising the at least one of a prong and a recess. 
     
     
         11 . The ventilation fan housing of  claim 9 , wherein the at least one of a prong and a recess is a prong having an arm extending from the housing and at least one nail extending from the arm. 
     
     
         12 . The ventilation fan housing of  claim 9 , wherein the at least one nail is three nails. 
     
     
         13 . The ventilation fan housing of  claim 9 , wherein the at least one nail is aligned perpendicular to the housing. 
     
     
         14 . The ventilation fan housing of  claim 9 , wherein the nail defines a triangular shape. 
     
     
         15 . A ventilation fan housing configured to house a blower, the ventilation fan housing comprising:
 at least one sidewall defining an interior space, an inlet opening into the interior space, and an outlet aperture spaced apart from the inlet;   at least one recess defining a crest and a base, wherein the base defines a base aperture in the housing;   at least one nail extending away from the recess toward the base aperture;   wherein the at least one recess is configured to be deformable to allow the at least one nail to pass through the base aperture.   
     
     
         16 . The ventilation fan housing of  claim 15 , wherein the housing further comprises at least one mounting flange extending from any exterior of the fan housing and the mounting flange comprising the at least one recess. 
     
     
         17 . The ventilation fan housing of  claim 16 , wherein the at least one mounting flange defines at least one mounting aperture to receive a fastener. 
     
     
         18 . The ventilation fan housing of  claim 15 , wherein the at least one recess is defined in the at least one sidewall. 
     
     
         19 . The ventilation fan housing of  claim 15 , wherein the dome defines a crest aperture at the crest and the at least one nail extends from a perimeter of the crest aperture. 
     
     
         20 . The ventilation fan housing of  claim 19 , wherein a fastener can pass through the crest aperture after the recess has been deformed.
