The KN Series units are multidirectional rectangular diffusers with extractable cones. The costruction variants of the central body allow several throw configurations of the diffuser. They are used both in supply and extraction for ceiling installation. The removable central body makes easier the regulation of the volume control damper and it does not require counterframe installation.
