Description
ASLI SW-MO swirl diffuser is a type of diffuser with fixed radially control blades in matrix arrangement. This unique type of slots combines the characteristic of jet and swirl diffuser, which produce “vortex” air flow allow a high change of air rates and remove heat load effectively, especially at the occupied level. It is suitable for rapid cooling and mixing with room air. The SW-MO swirl diffuser can used as return and exhaust type device.

Introduction
The use of sunshades to reduce solar heat gain through glazing is recognized as an important enhancement in modern buildings. With increasing emphasis on control of indoor environments and the need to reduce energy consumption, planning for solar gains is necessary even in air conditioned buildings. Energy saving through the use of sunshades would certainly ensure that your projects are more environmentally responsible. Besides making your building more GREEN, sunshades also provide the designer with added creative options.

Products Range
Basic ASLI sunshades assembly consists of outriggers, blades and fascia (optional). ASLI has several standards of outrigger, blade and fascia profile to choose from.

Description
ASLI FLD Round Floor Diffusers are specially designed for use in raised floor air distribution systems, where the floor cavity is used as a pressurized supply air plenum. FLD produces a high velocity swirl air pattern with the guidance of guide vane in the basket. Maximum comfort level could be achieved by producing high induction rates of room air with the design of FLD.

Materials

• Diffuser core : Aluminum die casting.
• Outer ring : Aluminum die casting.
• Housing : 0.7mm thickness galvanized steel.
• Basket : 0.7mm thickness galvanized steel.
• Plenum Box Internal Insulation : Fiber glass, 25mm, 32kg/m3.

Surface Finish

• Natural anodized or powder coated.

Features

• Used in raised floor air distribution systems.
• Swirl air pattern provides high induction rates of room air.
• Suitable for high ceiling air conditioning system.
• Air volume can be controlled by the butterfly damper or the basket blade.
• Dust tray catches anything that might fall through the diffuser face and is removable for cleaning.
• Air volume can be controlled by the butterfly damper or the basket blade.
• Aluminum die casting diffuser core provides high strength to withstand high weight load.
• Internal insulation to attenuate noises and prevents condensation for FLD-PB.
• The FLD-PB housing can be removed by simply rotating the housing and disengaged at the collar.
• FLDB can be installed without removing the floor tiles.

Standard Sizes

• FLD-S: 200ø, 250ø (mm)
• FLD-C: 250ø (mm)

Description
ASLI DQ is a type of diffuser with adjustable air control blades. This unique design focuses on the appearance of the diffuser, as well as the performance of the diffuser. It can perform 2-way, 3-way or 4-way air flow projecting horizontally from the face of diffuser to avoid direct throw to occupant’s zone.

Materials

• Diffuser : 1.0mm Galvanized steel
• Guide Vane Holder : ABS Plastic
• Guide Vane : Aluminium Extrusion

Surface Finish
White powder coated, oven baked as standard

Features

• Air flow pattern can be adjusted to 2 way, 3way or 4-directional throw
• Balance between aesthetic appearance and performance
• Horizontal throw reduces direct-throw of air on occupants
• Standard size available for T-bar ceiling on metric or imperial size

Standard Sizes

• 595mm x 595mm
• 603mm x 603mm

Accessories

• Plenum box
• Radial blade damper (C1)
• crown damper (C2)
• Round inlet adaptor (D2)
• opposed blade damper (G1)

Description
ASLI Variable Air Volume (VAV) terminal units are volume flow rate controller for supply air on variable air volume system. These units are designed to control the airflow rate of conditioned air into an occupied space in response to a control signal from thermostat or Building Automation System (BAS). They could be used in stand alone system or interfaced with LONWORKS or BACnet.
