I have the following:
Wall Fan - 10D995
Fan Guard - 1WBT8
Wall Shutter - 4C556
I need the Grainger Item # for the Weather Hood to fit this system.
Another question is, "Do I need a wall housing or does the Fan Guard serve as the wall housing?" The wall housing is 3FKF4 for the 12" fan.
The 10D995 can use weather hood 16D556. I will caution you that the wall shutter 4C556 should not be used with a hazardous location fan. You should use the 3FKF4 in place of the 1WBT8, as it is the housing and fangaurd. If you have more application questions you can call HVAC tech support at 800-472-4643.
