Transfer air solutions

Guide for selecting the right transfer air solution

When standard transfer air diffusers are not suitable due to various circumstances, e.g. sound requirements, air flows or where a flexible installation is needed, several of Swegon's products can be combined to solve this.

There are several solutions depending on whether installation is to be done through wall, ceiling to ceiling or ceiling to wall.
