¿ Branch pipe (PDF 23C3, PDF 46C3)
If there are obstacles such as partitions inside the room that prevent
the air from circulating correctly, branches can be installed to
provide an even air temperature.
Suitable return air grilles must be installed in line with the volume
of return air. If air conditioning is provided in an adjoining room,
always install a return grille.
Example of a branch pipe.
