2 SERIES G djustable Slot Swirl Diffusers Introduction Series G provides a new added dimension our popular and effective swirl diffuser theme. Complimenting Gilberts existing swirl diffuser range the new G series has been introduced provide a wider range of architectural and design style swirl diffuser options which combine appealing aesthetics with cost effective alternative design. Primarily the diffuser offers a fixed size square fascia designed fit both plaster ceilings and standard 600mm sq ceiling grids. choice of four different List Size radial blade pattern configurations provide for a wide range of different air volume selections. Each model provides a high performance swirl air distribution effect which allows them deliver high volumes of air in the conditioned space taking advantage of its rapid entrainment and mixing capabilities. Series Options order Options Series G- - Swirl diffuser suitable for plaster ceiling applications Series G- - Swirl diffuser with clip in border edge detail Series G-C - Swirl diffuser with borderless frame suitable for lay- in ceiling grid application. Series G-D - Swirl diffuser with step flange border frame suitable for tegular ceiling grids. Face Styles 0 Pattern 315 Pattern 500 Pattern 600 Pattern ll units are fabricated from galvanised steel and are available with a matching range of p and side entry plenum boxes. Volume control can be achieved using Quadrant flap type or Iris Dampers on the plenum inlet spigots. There are just 4 List Sizes defined by the primary swirl area with 500 and 600 patterns. ll patterns are built in a 600 sq fascia using four alternative border styles suit popular ceiling grid designs. Standard fixing uses a central screw in a secondary bracket built within the plenum box. Special L fixing for installations without plenum are also available. Standard diffuser finish is Polyester Powder White. Other colours available on request. Selection Procedure Performance Data The following selection procedure is be used within areas with ceiling heights between 2.5 and 4 m and is based on an evenly distributed layout of diffusers. 1. Try if possible construct in plan an imaginary square ceiling grid. This will enable the Designer position each diffuser at each square centre so that the distribution is even in all directions. 2. The tal volume of air should then be divided by the number of outlets and the volume per diffuser established. 3. The performance chart should then be used select the size of diffuser based upon the volume and throw requirements. For high ceiling applications an over-blow situation can be acceptable. 4. Check pressure loss and noise levels from the design chart confirm acceptability. The performance tables that are illustrated in the brochure give a tabulated performance for each listed size of diffuser, gether with their design. The figures given relate cooling, ventilation and heating applications and are given for a horizontal distribution. 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. EXMPLE: Take a 6 x 9 m open plan office area with a tal required air volume be supplied of 0.6 m3/s. Divide this area up in 6 equal spaced segments, each measuring 3 x 3m, and position a diffuser in the centre of these imaginary grids. If we divide the tal volume by 6, then this will equate 100 l/s per diffuser. From the chart for a size 500 in a horizontal distribution, we can select a unit handling 100 l/s which gives a noise level of NC, and a static pressure drop of 13 Pa. in isothermal conditions of 0.8m at 0.5m/s and m at 0.m/s terminal velocity, which is very similar whether in a heating or cooling mode. This should be an acceptable selection for this area assuming a standard room height. References Used Pressure: ll pressures are given in Pascals (Pa) (Newn per m2). : The horizontal distances are given for both 0.5 and 0. m/s terminal velocities and are based upon ceiling effect for horizontal distribution. Sound: The noise values are peak values taken on the relevant curves. 2
