The square-cone-type Directional Diffuser standard frame is constructed from extruded aluminium. It has a flat outer border or alternatively there is bevelled type border which lowers the diffuser face 50mm proud of the ceiling.
The standard frame can slot into a T-bar or be mounted into a plaster ceiling. The core is removable and there are five different styles to choose from depending on the air distribution requirements, see application section. If a standard 4-way core is preferred for the overall aesthetics then blanking plates can be ordered to distribute the air in any of the five different patterns; 1 way, 2 way, 2 way corner blow, 3 way or 4 way.
The standard finish is powdercoat white and baked at a temperature of 180°C to help resist impacts and abrasions.
