Panel floor grilles take a load off the specifier’s mind

Available in a wide range of load-bearing capabilities — Air Diffusion’s panel floor grilles are 599 mm square as standard.
Air Diffusion’s latest range of panel floor grilles is available with full detail on the structural point loading of each standard model. These grilles are designed for raised access floor systems and come in three standard options — light duty, medium duty and heavy/extra-heavy duty to meet the structural loading classifications detailed in BS EN 13264:2001. All models replace floor tiles and are suitable for supply- and return-air duties and incorporate features to ensure a smooth and unbroken floor finish and easy relocation if the office layout changes. Other features of these grilles include brushed-aluminium finish. A black nylon coating and other colours, plus the option of a shadow-line finish are also available. Model LDA is a light-duty grille which can be supplied with an optional opposed-blade damper. It is constructed from aluminium extrusions with a reinforced frame and is ideal for nearly all residential applications. The MDA is designed for medium-duty applications and has a single-piece multi-blade mitred frame. Installation is simplified by the incorporation of a recessed-flange arrangement compatible with the raised-floor jacks using by flooring manufacturers. Some applications, such as offices, require panel floor grilles with an integral overlapping flange to suit edge-seamed floors. Model F48 provides a solution. It is a medium/heavy-duty floor grille of heavy-gauge aluminium extrusions with a 48 mm-wide flange frame. Heavy-duty requirements are met by Model HAD. Model HDA-R is supplied with an aluminium opposed-blade damper that can be adjusted through the grille core.
