Fixing
Standard fixing of our slot diffusers is by use of a standard plasterboard jointing compound which can then be sanded and painted. On new-build sites, the plenum and diffuser are normally hung together and the plasterboard then cut and introduced to the face of the diffuser. Further instructions to install the hidden linear diffuser can be found on the video option above.
Inaudible Output Of Linear Slot Diffusers In Increasing Order
The following airflows for each linear supply diffuser give a noise level of 17dB. Installers often use 25dB as the level of inaudible noise. We use a lower figure for each hidden linear slot diffuser to allow for other fixings such as dampers and other constrictions upstream of the diffuser and also to allow for some margin of error.
