Evacuation system if several dryers are connected to a common evacuation duct
(except gas heating machines):
If several ironers are installed with a common evacuation duct, the cross section of the evacuation duct must in-
crease as a function of the number of installed machines so that each of them operates at the same value of air
resistance..
Use elbows (and not Tees) to allow the air to pass forwards.
The simplified figure below shows the principle on which the evacuation duct shape is designed.

The indicated evacuation diameter is the dryer outlet diameter.
Cross-sections of ducts between dryers and the outside of the building must be designed taking account of the flow
and the allowable head loss on each machine and the routing of ducts (elbows and lengths).
Please call us if you are in any doubt about the layout of your exhaust device if you are modifying an existing
installation.
