Colman’s range of Supply Grilles have been designed to compliment our extensive range of Return Air Grilles. The range is suitable for side wall applications and is available in a wide variety of styles and sizes to suit individual application requirements.
With three standard frames and three styles of core, the range provides a flexible group of side wall grilles to meet most functional and installation requirements. Grilles are manufactured with extruded aluminium flanges, and are complete with aluminium aerofoil blades, resulting in a clean aesthetic appearance.
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.
For applications requiring an adjustable air pattern, our uniquely designed steel ‘A’ core assures rapid diffusion and a high rate of aspiration. The core can be reversed and inverted in order to select either an upward or downward air pattern of 5 or 15 degrees.
