Flow-through Insect Screen

Abstract

An insect screen and the methods for using the insect screen are provided. The invention includes an insect screen, which can include a body having an internal volume and side walls that include mesh screen. The insect screen can also include means by which to extend the insect screen from the emergency drain line of a residential or commercial HVAC system.

What is claimed is: 
     
         1 . An insect screen, comprising:
 a main body having side walls, wherein at least a portion of the side walls comprise mesh screen; and   a means for extending the insect screen from the distal end of an emergency drain line of an HVAC system.   
     
     
         2 . The insect screen of  claim 1 , wherein the mesh screen extends about a circumference of the main body. 
     
     
         3 . The insect screen of  claim 1 , wherein the connection means includes a threaded connector disposed at a first end of the insect screen. 
     
     
         4 . The insect screen of  claim 1 , wherein the mesh screen is about 20-mesh to about 40-mesh. 
     
     
         5 . The insect screen of  claim 3 , wherein the mesh screen is about 20-mesh to about 40-mesh. 
     
     
         6 . The insect screen of  claim 3 , wherein the insect screen allows condensate to exit the emergency drain line through the mesh screen. 
     
     
         7 . An insect screen assembly, comprising:
 a main body having an internal volume and side walls comprising a mesh screen; and   a connector for extending the insect screen from the distal end of the emergency drain line of an HVAC system.   
     
     
         7 . The insect screen of  claim 7 , wherein the mesh screen is between 20-mesh and 40-mesh. 
     
     
         8 . The insect screen of  claim 7 , wherein the mesh screen is 30-mesh. 
     
     
         9 . An emergency drain line insect screen assembly, comprising:
 an emergency drain line of an HVAC system; and   an insect screen comprising:
 a main body with an internal volume, 
 one or more side walls comprising a mesh screen, and 
 a connector disposed about the first end of the insect screen and configured to connect the terminal end of the emergency drain line. 
   
     
     
         11 . The insect screen of  claim 9 , wherein a first end of the conduit is removably connected to the insect screen and wherein a second end of the conduit is connected to the drain line. 
     
     
         12 . The insect-screen-system of  claim 9 , wherein the conduit further comprises a flange. 
     
     
         13 . The insect screen system of  claim 9 , wherein the mesh screen is about 20-mesh to about 40-mesh. 
     
     
         14 . The insect screen system of  claim 9 , wherein the mesh screen is about 30-mesh.
