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.

AUR
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.

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 = 0.0355m2.
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 = 0.0284m2.

Performance Graphs
Throws shown are to a terminal velocity of 0.60m/s and 0.30m/s respectively. Encountered air velocities will depend
on room configurations and the occupant satisfaction depends on the location of the terminal air velocity in relation to
the occupied zone.
These graphs are for selection only and should not be used for commissioning.
The throw data is based on isothermal air.

SLIMLINE WALL GRILLE
AST, AAT
Description
The Slimline Wall Grille is designed for use in supply, return or exhaust air applications. They are manufactured from
high quality aluminium extrusion with a choice of two blade angles, 0° and 15° and supplied as standard with a flange.
They are recommended for side wall, or bulkhead mounting.
A variation on the standard Slimline is the flangeless type which is popular with architects which utilises an “I” frame to
hold the bar assembly.
All grille core assemblies are mounted in a sturdy frame and can be either fixed core for security purposes or
removable core for easy access. For Y sizes over 500mm and X sizes over 1200mm the core is fixed. Note for ceiling
applications the grille must have a fixed core.
The standard finish is natural anodised or powdercoat white but other colours available upon request.

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.

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.

Letter “R” denotes a round diffuser.
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.

CIRCULAR DIFFUSERS
ACDSC,
ACDRA
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.

ROUND CEILING DIFFUSER
ARCD
Description
The Round Ceiling Diffuser is fabricated from spun aluminium and typically used for supply air diffusion but
alternatively can be considered as an attractive alternative for bathroom exhaust applications.
The core is adjustable and acts as both a balancing damper and pattern control.
The diffuser can be fixed into position using the fixing clips provided. The standard finish is white electrostatic
powdercoat.

ADJUSTABLE JET DIFFUSERS
AJD, AJA
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.
