Product Description

Our SLD slot diffuser is a versatile, flexible and cost-effective linear slot diffuser. As the manufacturer of these slot diffusers, we can offer them in a wide range of options.

They can be specified as linear slot diffusers for ceilings or linear slot diffusers for sidewalls as they are available with special edge trims to complement their installation.

Linear Slot Diffuser Fixing

Standard fixing of our slot diffusers is by means of concealed ‘U’ brackets into hemmed plenums. Alternatively, they can be secured by fixing to the rear of the ceiling surface material.

Our standard construction includes welded end flanges, providing clean lines without any visible joints.

High Capacity Linear Slot Diffuser

The SLD is a high capacity linear slot diffuser. It has been specially designed to handle more air volume at lower sound levels, pressure drop and with a shorter throw than most comparable linear slot diffusers.

The SLD is available in the following multiple slot linear configurations. These enable you to align with your design and performance requirements.

  • 1 slot linear diffuser

Plenum Boxes

Our Plenum boxes are accessories specifically designed for use with our Grilles and Diffusers. They have been developed to equalise the pressure profile within the box. This then provides an even velocity at the face of the grille or diffuser. No need for equalising grids.
