Configuring the room ventilation opening
Rooms in which rotary irons and tumble dryers are operated must have an induced
ventilation system (e.g., ventilation slots in windows and doors, wall openings with
grilles, or opened windows or skylights).
For example 1
A duct diameter of 6" (150 mm) was specified in example 1. According to this duct diame-
ter, a room ventilation opening with a size of 17' 5" (531 cm) is required. The edge length is
9 1/16" (230 mm) (see Table 3).
For example 2
A total duct diameter of 8 11/16" (220 mm) was specified. According to this duct diameter,
a room ventilation opening with a size of 37' 4" (1,140 cm) is required. The edge length is
14 13/16" (377 mm) (see Table 3).
For example 3
Since in this case the tumble dryer is connected to a central air supply, additional ventila-
tion openings are not needed.
