Abstract

A high-flow ember shield building ventilator for use with roof or attic exhaust systems has a substantially rectangular outer frame portion with four side walls and a bottom wall, and a folded screen insert inserted into an opening of the frame portion. A cylindrical frame having a screen installed thereon is mounted onto the rectangular frame portion over the folded metal insert. A high-flow ember shield alternatively has a cylindrical frame with a screen insert formed by concentric rings of mesh material.

Claims (25)

1 . A high-flow ember shield building ventilator for use with roof or attic exhaust openings, comprising:

a substantially rectangular outer frame portion with four side walls and a bottom wall; a folded screen insert inserted into an opening of said frame portion formed by said

side walls and said bottom wall;

a cylindrical frame having a screen installed thereon, wherein said cylindrical frame and said screen are mounted onto said rectangular frame portion and over said folded metal insert.

2 . A high-flow ember shield building ventilator as in claim 1 , further comprising at least one attachment clip for mounting said cylindrical frame onto said rectangular frame.

3 . A high-flow ember shield building ventilator as in claim 2 , wherein said at least one attachment clip comprises four spaced apart attachment clips.

4 . The high-flow ember shield ventilator of claim 1 ,

wherein said folded screen insert has a plurality of folds at a substantially 15 degree angle.

5 . The high-flow ember shield ventilator of claim 1 , wherein said folded screen insert is made of metal.

6 . The high-flow ember shield ventilation of claim 1 ,

wherein said folded screen insert has a plurality of openings of about ⅛ inch in size.
