The Shadowline Diffuser Pro is designed to be used in conjunction with an inline fan, ducting and external grille (sold separately); or as part of a ducted air conditioning system. It can be installed at the wall/ceiling junction (shadowline) or in the ceiling.

The Shadowline Diffuser Pro has a modular design so that the units can be joined together and extended to any length to suit any wall/ceiling size. Depending on the length required, extra spigots and Y duct pieces may be required to connect the spigots to the fan. Refer to the product fact sheet for more information.

A LED light strip kit can be installed inside the Shadowline Diffuser Pro for an ambient lighting effect. LED light strips are adjustable in length and are available in warm, cool and daylight colour temperatures.

It is recommended that installation of the Shadowline Diffuser Pro is carried out by a qualified tradesperson.

The Shadowline Diffuser Pro should be installed prior to wall and ceiling gyprock sheets being installed. The gyprock is then set to the shadowline finish.
