2 SERIES DG Louvred Face Ceiling Diffusers Introduction Gilberts DG Series of Louvred Face Diffusers offer a distinct new evolution on a popular design theme. Combining up-to-date styling and design technology to blend with modern architecture the DG Series provide an unrivalled blend of performance and aesthetics featuring a restyled improved blade profile to give a balanced visual appearance from all aspects and angles and to ensure a clean horizontal air distribution pattern. Units are available in 1, 2, 3 or 4 way blow, in both square and rectangular forms and in a wide variety of sizes ranging from 0 x 0 neck size up to 00 x 00 in 75mm increments. (Where uniform core appearance is needed clip on blanking plates are available to convert air patterns). ll Gilberts DG Units benefit from a robust spring loaded removable core assembly which allows easy access to dampers for initial balancing or cleaning and safety cords to firmly secure the core to the diffuser frame. In keeping with contemporary ceiling design the series is available with 4 specific frame border styles integrating operational flexibility by matching different popular ceiling types. Standard Series Options: Type DG : Standard border suitable for both suspended and plaster ceiling applications. Type DGB : Special border adapted for clip in ceiling grid applications. Type DGC : Special border adapted for tegular and drop in tile ceiling grids. Type DGD : Narrow border option providing a higher capacity neck size suitable for suspended ceiling applications. Selection Procedure Performance Data Further adaptations on these border frame platforms provides other distinct permutations allowing integration of the DG into almost any ceiling type, specification or design. For volume control the standard screwdriver operated opposed blade damper is available attached directly to the diffuser. lternative plenum volume control options of a rotary damper, for top connection and quadrant or cord operated flap type damper for top/side connection can also be specified. Standard finish for all DG Series is a Polyester Powder White. Other colours and finishes are available on request. Having established the position where terminals can be sited, refer to data showing core pattern details and select the suitable direction pattern required. Knowing the volume and throw for each diffuser in question then check : a) Recommended limit of volume per direction according to ceiling height (table 1) with throw of air required lying between the max and min values. b) Note sound level from performance data and check this recommendations shown on table. c) Determine the total pressure drop from performance data.

They are intended to be aids to heating and air conditioning engineers. References used : Pressure : ll pressures are in Pa (N/m 2 ) TP = Total Pressure SP = Negative Static Pressure Throw : The first figure is the throw that corresponds to 0.5 m/s, and the second figure corresponds to 0. m/s. Sound : NC values are based on a room absorption of db, re -12 watts and for one diffuser, with OBD Damper fully open. Return Factors : If the unit is used as a return inlet, the performance data is obtained by applying the factors in the following manner : a) Sound : dd factor to the NC value listed b) Negative static pressure : Multiply the factor by the total pressure listed in the tables. Return Example : 0 x 0 DG4 with 0.02 m3/s being returned through the unit Return NC = + 1 = Return Pressure = (-SP) x 1.1 = Pa Plenum Boxes : Where plenum boxes are attached to diffusers there will be an effect on both the noise and pressure drop values. Top connection boxes have little effect unless spigot connection velocities exceed 4 m/s. However for Side entry boxes an increase should be applied to the tables of % for supply pressure drops and 40% for extract. The following spigot velocity figures indicate expected NC levels in the conditioned space and are based on a room absorbtion figure of db, re -12 watts. Spigot Velocity m/s NC Level -35 Spigot Velocity m/s NC Level Spigot Velocity 2.3 m/s NC Level - Spigot Velocity m/s NC Level The performance data for all Gilberts products is derived using a Gilberts plenum design and specification. Performance cannot be guaranteed where alternative plenum designs are used. Gilberts Supply Diffusers have been tested within the range of +/- ºC (as recommended in the HEVC Guide to ir Distribution Technology). For any other temperature differential requirements please contact our Technical Department. 2

3 Facilities REMOVBLE CORE (fig.1) The Louvred Face Core on all DG Series units is spring loaded to allow easy removal from the frame for cleaning, damper balancing and adjustment. To remove the core simply identify its spring spring loaded side and gently push the core horizontally towards the outer frame. Upon reaching its maximum movement the clips or pins on the opposite side of the core will have disengaged from the frame allowing that side to lower for full removal. Note : lthough safety cords are fitted the core will remove sufficiently to clear the frame and lower but will remain safely secured to prevent it from falling. The removable core facility also allows different core styles to interchange on site where necessary. (fig.1) DMPER CONTROL (fig.2) The DG Series now offers a variety of alternative damper control choices. Standard Opposed Blade Dampers remain an option for all units with screwdriver operation. In addition, however, a Rotary Damper is also available for units with Top Connection Box (TCB) type plenum. The rotary damper benefits from a low depth profile and comprises of a hit and miss style circular sliding plate which can be adjusted using finger tabs from the damper face. For top and side entry plenums quadrant and cord operated single blade flap type dampers can also be utilised or, for a more sophisticated form of volume control, Iris type dampers. (fig.2) SFETY CORD (fig.3) standard feature on DG Series are the Nylon Safety Cords. The cords which are approximately 0mm in length bind the removable core to the diffuser frame. useful safety feature, the cords will allow core removal but will prevent the core from accidently falling to the ground. (fig.3) NON VISION COWL (fig.4) For non-ducted installations DG Units can be fitted with a matt black non-visual cowl plate (Ref: NVC/DG) at the rear to prevent see through vision into the ceiling void.

4 SERIES DG Louvred Face Ceiling Diffusers Coanda Plate vailable to suit all square sizes the coanda plate fixes to the back of the face flange of the diffuser to create a ceiling effect where diffusers are mounted in free space such as on exposed ductwork. The coanda effect can be used to increase the throw of the diffuser in these applications by allowing the air to flow across the plate and travel further before dropping into the occupied zone. Standard Coanda width = List Size + 374mm Coanda Plate Coanda Plate Coanda effect on airflow Neck Reducing Plate Neck reduction plates can be fitted to the rear of all square face diffusers and are designed to limit airflow through the diffuser to a smaller neck size. Typically they are used on standard 00 sq ceiling grid size diffusers allowing the tile replacement size to be used throughout an installation whilst matching capacity to the required volume. If opposed blade dampers are used in conjunction with a neck reduction plate the damper is also downsized with the neck to save on cost. ir Pattern Options 1 - WY BLOW 2 - WY BLOW TYPE DG1 TYPE DG1L 3 - WY BLOW TYPE DG2 TYPE DG2L B B B B TYPE DG2E 4 - WY BLOW TYPE DG3 TYPE DG3L B B TYPE DG4 TYPE DG4L 4
