Linear Diffusers and Bar Grilles

Linear type diffusers and grilles have been developed to satisfy architectural and engineering applications that require a continuous length appearance, aesthetically pleasing design and high engineering performance with premium quality aluminum products.

Installations can be equally effective where lengths are literally continuous around the periphery of a wall, floor or ceiling space and certain sections of the unit are active with regard to air flow, satisfying mechanical and architectural requirements or individual discreet lengths may be separately installed at reduced cost and offer the same engineering performance.

The proposed application and installed location will usually dictate whether a slot or bar type product is the most suitable choice. When the ideal product type has been chosen, the air flow and performance required will dictate the style and sizing requirement from a comprehensive range of available sizes and capacities.

Linear Slot Diffuser

Model Series 5000 provides architectural excellence and outstanding performance flexibility. Available in three different slot opening widths, a range of 1 to 10 slots and a wide choice of border/frame styles that co-ordinate with ceiling and installation details. They feature 'ice tong' style individual pattern controllers in each slot that not only offer a 180°air pattern adjustment,but can also be used to dampen airflow.
Designed primarily for ceiling and high sidewall installation, they are eminently suited to, and recommended for, VAV applications. They maintain tight and stable horizontal air pattern over a wide range of air volumes by utilizing the maximum ceiling coanda effect.
Also commonly used in overhead heating applications, the versatile pattern controllers allow vertical projection of heated air to meet almost any perimeter condition.
Supply Air – Models 5050, 5075, 5010
Return Air – Models 5050R, 5075R, 5010R
Plenums for Linear Slot Diffuser

Model Series 5300 Plenums are designed to fit the 5000 Series Slot Diffusers. The plenums are constructed from corrosion-resistant steel and are available in two different styles for an extensive performance range. The standard constructed plenum is suited for applications that require longer throws and shorter spreads, whereas the modified plenum increases the spread and reduces the throw. Specially designed end caps can be turned up for continuous runs. All styles are offered with internal or external insulation.
Standard Performance (non-insulated) – Models 5350, 5375, 5310
Standard Performance (internally insulated) – Models 5350I, 5375I, 5310I
Modified Performance (non-insulated) – Models 5350MP, 5375MP, 5310MP
Modified Performance (internally insulated) – Models 5350IMP, 5375IMP, 5310IMP
Linear Bar Grilles

Model Series 4900 provides an extruded aluminum bar grille that offers beautiful styling and efficient performance. Linear bar grilles offer a choice of fixed air patterns with 0°, 15°or 30° air deflection, a choice of bar widths and spacing and a wide choice of border/frame style combinations to suit most types of installation. They are available with an optional opposed blade damper for volume control. Linear bar grilles are recommended for supply air applications in floors, window sills, and high sidewall locations. They are not generally suited to ceiling mounted supply applications (other than for directional spot heating or cooling as an air curtain) as they are not designed for horizontal projection from the face.

Models: 49-240, 49-241, 49-243, Suffix '-O' adds a steel OBD
Linear Louver Diffusers

Model Series: 48LL
Linear Louver (Vane) Diffusers are designed to provide a high capacity, architecturally pleasing linear diffuser that can supply large volumes of air at relatively low sound levels and pressure drops. High quality, extruded aluminum angular discharge louvers are designed to create a stable horizontal air pattern that is tight to the ceiling. Ideal for applications in VAV systems, these diffusers create a strong ceiling coanda effect at typical maximum and minimum flow rates and ensure optimal comfort conditions.

Models: 48LL1 and 48LL2
