High induction linear wall slot diffuser with alternating multi-stream mini-jets discharged by nozzle barrels. Nozzle barrel discharge direction is individually adjustable through 90° to alter air pattern vertically. Suitable for installation in the side of a wall or bulkhead. Modular or continuous aesthetic.

	Location – side: Air supply from sidewall, bulkhead or side of duct.
	Mixed flow discharge: High aspiration alternating multi-stream mini-jet discharge from adjustable barrel nozzles located in linear slots intensely mixes supply air with room air, producing strong supply air dilution with rapid discharge velocity decay. Low velocity, high momentum supply air motion of substantially uniform temperature distribution over short or long throws is achieved. Ideal for enhanced thermal comfort (ADPI ≥ 90%).
	Return air: Suitable for use as a return air inlet.
	Adjustable direction: Individual barrel discharge rotation through 90° for vertical air pattern adjustment. Horizontal or inclined discharge provides draught-free cooling; downward discharge provides effective heating.
	Manual adjustment: Air pattern direction adjustment is manual.
	Linear face shape: Modular or continuous linear aesthetic, each with flanged or flangeless edge profiles.
	Slot face pattern: Barrel nozzles create linear slot appearance, with 1 to 4-slot options.
	Plastic Face: Black plastic adjustable barrel nozzles.
	Metal Face: Anodised or powder coated linear aluminium profiles.

Options

	Mounting Frame: Suitable for rendering into plaster board bulkhead or wall. Diffuser clips in from side.
	Plenums: Connection boxes with concealed diffuser fastenings.

Function

The SMARTEMP® Linear Multi-stream Wall Diffuser, type LMW-AD, is a high induction linear slot wall diffuser. Alternating mini-jet discharge from a mulitude of individually adjustable barrel nozzles provides vertical discharge direction adjustment of the multi-stream air pattern. The diffuser can be flush mounted to the side of a wall or bulkhead, and is available with or without face flanges.

The diffuser’s 1 to 4-row linear slots comprise a multitude of nozzle barrels, each with vertical discharge direction adjustment to produce highly inductive discharge by breaking up the supply air stream into a multitude of micro-jets.

The barrel nozzles are made of black polycarbonate, each with an adjustable guide vane, and are located in aluminium extrusions that are anodised or powder coated. Each guide vane can be easily adjusted to alter the micro-jet discharge direction up or down.

High induction discharge offers many advantages. High aspiration causes intense mixing at the diffuser discharge face, strongly diluting the supply air stream with large quantities of room air. High induction provides rapid temperature equalisation of the supply air stream with room air, preventing cold air dumping, thereby ensuring uniform temperature distribution (no cold and draughty or hot and stagnant spots) and high comfort levels in the space.

High induction also improves heating performance, as rapid supply-to-room air temperature equalisation prevents the supply air from being overly buoyant.

The stable discharge characteristics of the diffuser over a wide range of supply air temperatures and volume flow rates make the LMW-AD suitable for standard or low temperature air conditioning systems, with constant flow or VAV, whilst maintaining uniform temperature distribution and high levels of draught-free comfort in the occupancy space.
