This range of Return Air Grilles have been designed to complement our Supply Diffusers for both side wall and ceiling applications. The range is available in a wide variety of styles and sizes to suit individual application requirements.
With three standard frames and four styles of core, the range provides a flexible group of grilles to meet most functional and installation requirements.
Grilles utilising our ‘B’ style frame have integral cores which are retained by spring clips on the rear of the extrusion, whilst the ‘H’ style houses the core in a U channel panel frame, removable from the face and allowing access to the duct without having to remove the whole grille.
