DOUBLE DEFLECTION GRILLE AUR SECTION A - GRILLES AND LOUVRES Description The Double Deflection Grille is designed for use in supply applications but equally suited to the return air installation. The grilles have adjustable blades fitted horizontal in the front and vertical in the rear. There is an optional removable grille core to facilitate ease of installation and cleaning. All grilles feature attractively designed extruded aluminium features. A single deflection grille is available fitted with front horizontal blades only. Standard finishes are in natural anodised or powdercoat white but other colours available upon request.

DOUBLE DEFLECTION GRILLE AUR SECTION A - GRILLES AND LOUVRES Ordering Procedure Product range selections are based on the nominal neck size X & Y. Example: If your requirement is for a 12 x 12 (300mm x 300mm) grille with a removable core, the ordering code would be AURR1212. Note - Shaded areas indicate standard product. Dimensions Bradflo reserves the right to make changes to product without prior notice V16.1 Page 5
DOUBLE DEFLECTION GRILLE AUR SECTION A - GRILLES AND LOUVRES Application Free area for standard size double deflection grilles. Free Area Factor To calculate the free area, the grille s nominal area is multiplied by f1, where f1 is a correction factor and is determined by the graph. For single deflection the nominal size is the grille s Y dimension. For double deflection it is the grille s X dimension. Example: Size 300 x 150 single deflection. From the graph, f1 = 0.79 for the grille height of 150. The grille s free area is therefore: 300/1000 x 150/1000 x 0.79 = 0.0355m 2. For a double deflection include the factor f1 for the grille length. The free area would therefore be: 300/1000 x 150/1000 x 0.79 x 0.80 = 0.0284m 2.

HIGH VOLUME SWIRL DIFFUSERS PHVSD SECTION B - DIFFUSERS Description The High Volume Swirl Diffuser provides a uniform radial pattern of air across the ceiling to provide a good temperature distribution with minimal draughts in the occupied zones. The design ensures comfort can be maintained across a broad range of flow rates. It is designed to be either flush ceiling mounted in a grid section or plasterboard mounted. The plenum is fitted with an internal diffuser plate to improve the pressure distribution. The diffuser is secured by a single centre screw and hidden from view behind a push-on decorative cap. For lower flow rates, restriction rings (#1 to 5) are available for the PHVSD595-500 and aesthetically hides inside the neck behind diffuser face. Square or round face swirl diffusers are available with size details on the next page. The standard finish is a white (RAL9016) powder-coat but other colours are available.

There are five sizes of ring insert available to downsize PHVSD595-500 for lower flow outlets. Rings are identified using a suffix e.g. / 5 for the smallest aperture ring. Dimensions Application This type of diffuser utilises the coanda effect to efficiently traverse the ceiling and envelope the occupied space with a supply of conditioned air. It is important to separate the units adequately to avoid undesirable collision velocities. Bradflo reserves the right to make changes to product without prior notice V16.1 Page 61

CIRCULAR DIFFUSERS ACDSC, ACDRA SECTION B - DIFFUSERS Description The Circular Diffuser is available as a Cone type or a Plate type construction and fabricated from steel. These diffusers are commonly used in foyers, lobbies or arenas. They are designed to accommodate a range of flow rates using an adjustable core to supply diffused air in the horizontal plane. The Cone type unit can be adjusted to increase the vertical throw which reduces ceiling stratification during heating mode. The standard installation is ceiling mounted or fixed to exposed duct work. The core of the diffuser is easily removed for fitting and cleaning. The standard finish is white powder coated paint applied to a pre-treated surface and baked at 180 C to ensure a tough surface that resists damage, fading and discolouration. Selection Guide Ordering Procedure Example: If your requirement is for a 200 mm diameter ceiling diffuser, the ordering code would be ACDSC200.

ADJUSTABLE JET DIFFUSERS AJD, AJA SECTION B - DIFFUSERS Description The Adjustable Jet Diffusers are available in either of two designs 1) AJD - image left, 2) AJA image right. They can deliver high flow rates and depending on the required discharge profile be adjusted from a jet to a diffuse air pattern by rotating the nozzle through 360. This makes them suitable for applications such as the air conditioning or ventilation of large venues such as sports centres, theatres and industrial areas. The diffuser core is manufactured from spun aluminium and the outer case is steel. The entire assembly is powder coated and available in a range of standard colours.
