GRILL
APPLICATION

Linear Bar Grilles are commonly found in facilities such as

offices, shopping centres, hotels and airports etc. for both
supply and exhaust purposes.

Our Bar Grilles are mainly used for cooling, heating and
ventilation application. The design enables the manipulating
the airflow orientation and thus creating the desired flow
profile.

Our Bar Grilles can cater for various mounting methods

and different types of sizes to handle the required air flow,
patterns, pressure drops and sounds levels.

FEATURES

Available in highly customizable shape profile, our Linear Bar

Grille are designed to be used for the supply and exhaust air.
It is one of the preferred choice for providing aesthetic value-
added points.

CONSTRUCTION

GRILL
APPLICATION
To be used in facilities that has low noise requirements.
Our Return Egg Crate Grille is designed for return and
exhaust application.

With its large effective area, it is possible in obtaining

low noise and pressure loss and yet still preserving the
appearance of the grille. Our Return Egg Crate Grille is
highly effective in areas where high changeover rates
are needed.

FEATURES

Due to its unique design, the Return Egg Crate Grille

provides significantly higher free area from 70% to
90% as compared with other types of grilles.

Our Return Egg Crate Grille has a modern outlook

which blends in with any types of building facilities
which gives a clean and neat appearance.

EXTRUDED ALUMINIUM DIFFUSER
APPLICATION
With wide range of flow deflection designs, Ceiling
Diffusers are capable of providing excellent air
distribution (horizontal/ angled/vertical throw) for a wide
range of operating conditions. By arranging blade vanes
in pre-determine orientation, ceiling diffuser is able to
create multidirectional air flow from a single outlet (1-4
different flow directions).

Equipping with a Double Deflection centre core, ceiling

diffuser is able to provide flexible direction of air
distribution and yet maintaining superb horizontal
distribution (for individual cooling and conventional
uniform zone cooling).

Units of the diffusers have been tested at an independent N.A.T.A. accredited test laboratory in Australia. Test reports
can be provided on request. Throw and Noise Rating (NR) found in the performance data of this catalogue is based on
distance measured from the diffuser to the furthest point where the velocity is 0.25m/s and room absorption of 10 dB
in accordance to the recommendations of the Air Diffusion Council.

DIFFUSER
APPLICATION
The Round Diffuser has a versatile design to provide a
wide range of flow, ceiling height and supply temperature.
Due to its design, the Round Diffuser is suitable for use in
wide variety of buildings and applications. The multicore
design is mainly for high flow requirements and the single
plate/perforated core is mainly suited for high-end interior
designs, albeit lower flow.

The Round diffuser is also suited for both ceiling and

exposed duct installation. For switching between horizontal
and vertical throw, it is adjusted via rotation of the centre
core (clockwise/ anti-clockwise rotation). Due to the air flow
adjustment flexibility, the Round Diffuser is suitable for
use in individual, conventional uniform zone or with VAV
terminals.

DIFFUSER
APPLICATION
Suitable to operate with VAV system, the Swirl Diffuser can
operate over a wide range of varying airflow without effects
of dumping. Mainly used in areas with high heat loading
and high air change requirements, the Swirl Diffuser can
also be used for return and exhaust applications.

Air is introduced into an occupied space in a swirl vortex

motion, thus achieving high induction, high velocity and
temperature decay. This result in the supply air quickly to
mix with the room air, creating a uniform and comfortable
environment in the shortest time possible. Therefore with
its high induction effects, the Swirl Diffuser is capable of
eliminating drafts, stratification, concentrated cold areas.

DIFFUSER
APPLICATION
Commonly used in wide open spaces where duct work is not
possible but requiring proper ventilation, the Jet Diffuser
(JD) is able to deliver air to localised targeted area over large
distance up to 50m.

Depending on model type, the air flow direction is adjustable

in either one plane (2-way diffuser) or two planes (4-way
diffuser). With its aerodynamic design, the Jet Diffuser is
able to produces airflow at high outlet velocities without
compromising noise level.

With is fully rotatable centre core, the Jet Diffuser is able

to provide both the narrow and wide throw configurations
depending on the application requirements (the wider throw
provides better induction but at a shorter throw distance).

DIFFUSER
APPLICATION
Offers a concealed means of air diffusion to suit all light-
fitting design. Fabricate to customise to suit light fitting. The
availability of the sizes width of 12mm, 20mm and 25mm
slot. For the side inlet will be standard for both single and
double sided model.

CONSTRUCTION

Used for supply or return application. Besides, it is efficient

for wide ranging temperature differentials. Ideally good usage
for diffusing large volumes of air whilst maintaining low sound
pressure levels.

Built in curved blade pattern controller which is adjustable from

the face of the troffer air slot to provide a consistent horizontal
air discharge pattern and volume control.

It is also available in 600mm and 1200mm lengths to suit

standard light fixture lengths. For side entry, collar will be oval
and for the top entry, it will be round.

NON RETURN DAMPER
NON RETURN DAMPER

DAMPERS
APPLICATION

With its parallel action blades, the non- return

damper (LA-NRD) is designed to prevent backflow
of air. It can also be used to automatically shut-
off or isolate a section of the system to prevent
ingress of undesirable vapour and varmints.

The damper is opened by the air pressure

differential between two sides and it closed by
help of gravity.

It comes in vertical and horizontal installation

configurations.

CONSTRUCTION

• Parallel blade action

• Available in vertical and

horizontal configuration

• Damper sectioning: Minimum size: 100 x 100 mm

MATERIAL

STAINLESS STEEL CONSTRUCTION AVAILABLE

Frame • 0.8 – 1.2 mm galvanised steel

Surface finishing • 0.5 – 1.2 mm aluminium steel (For length <600 mm)

APPLICATION

The LA-OBD is an optional accessory (also known

as rear assembly components) supplied with
grilles and diffusers.

It is used for fine adjustment of air flow, for

balancing the air distribution system. The design
emphasis is on simplicity and durability for
reliable operation.

VOLUME CONTROL DAMPER

DAMPERS
APPLICATION
With its opposed blade operation closing system, volume
control damper (LA-VCD) is designed for controlling air flow
and pressure in HVAC systems. Designed to operate with
opposed blade action (providing better aerodynamics),
volume control damper provides better balancing control or
airflow rates.

Blades are formed from single skin construction with

grooved blade tips to produce an interlocking blade closure,
either via manual or automatic operation.

Manually operated dampers are supplied as standard with

a lockable quadrant assembly, thus allowing for conversion VCD-OVAL
to motor operation without the need for additional
components.

PRE-INSULATED DUCTBOARD
APPLICATION

Pre-Insulated Duct Boards are widely used in Air Conditioning and

Mechanical Ventilation (ACMV) systems due to their versatility, efficiency,
and ease of installation. They are suitable for various applications across
commercial, industrial, and residential settings.

Provides efficient and lightweight ductwork for cooling and ventilation,

ensuring optimal indoor air quality and thermal comfort. Lightweight
and corrosion-resistant properties make pre-insulated duct boards ideal
for harsh environments.

Ideal for environments that require robust and durable ducting with
effective thermal insulation to maintain temperature stability.

MATERIAL

Product Thermal Insulation Material

Brand Name ASA
Model(s): ASA Duct
Product Details Rating: Class 0

KEY PROPERTIES

Thermal Performance: ASA Duct Panel has a high R-value per

inch meaning it provides good insulation with a thinner layer.

Fire Resistance: ASA Duct Panel has good fire resistance

properties. It forms a char layer when exposed to fire, which helps to
protect the underlying material from further combustion.

Moisture Resistance: ASA Duct Panel has good resistance to

moisture, reducing the risk of mold and rot, making it suitable for use
in humid environments.
