4 6 Spigot Diameter 3 Diffusers Barrel Slot Diffusers CSB 1-P / CSB 1-F The Waterloo CSB 1 High Induction Barrel Slot Diffuser enhances our already comprehensive range of slot diffusers and complements the larger CSB 2. An attractive and efficient design makes the CSB 1 ideally suited to a huge variety of applications. Close pattern control gives the CSB 1 its highly adjustable air distribution characteristics, over much shorter runs than have previously been achievable. Constructed from extruded aluminium and ABS FR, the CSB 1 is designed to integrate seamlessly into any installation. In ceiling, sidewall and bulkhead applications, the CSB 1 will provide horizontal or vertical projection, and is suitable for both supply and exhaust ventilation.

Increase throw by 1m for every 1m increase in ceiling height. Apply a factor of 1.1 to throw values for isothermal conditions or vertical diffusion, and a factor of 1.1 for 10 degrees of heating. Noise level is based on diffuser sound power level less 8dB room absorption. Performance parameters for supply include plenums.

5 1 60 Spigot Diameter 3 Diffusers Barrel Slot Diffusers CSB 2-P / CSB 2-F The Waterloo CSB 2 Barrel Slot Diffuser is the one of the latest additions to our range of diffusers. CSB 2 has a slot opening of 2mm and has a rounded slot gap for improved performance and a sleek modern look. The CSB 2 ideally suited to a huge variety of applications particularly when high volumes and design integrity are required, such as office spaces. The 100mm rotating barrels have stepped adjustment which makes set up simple, air flow can be left, right or alternating dependant on your requirements. Constructed from extruded aluminium and ABS FR the CSB 2 is durable and perfectly suited for installation in continuous linear runs as single units, the design of the CSB 2 allows for the use of mitred corners which allows for continuous perimeter diffusers. The smaller CSB 1 is available when air volumes are lower or a more discrete diffuser is required.

9 Linear Slot Diffusers LCS The LCS Linear Slot Diffuser has been developed to offer a cost effective alternative to the infinitely variable CS range of slot diffusers. Available in 2, 3 or 4 slots it comes complete with a black anodised aluminium pattern control element and will provide either a one or two way horizontal distribution. The LCS can be combined with the standard CS flange and plenum combinations.

Continuous diffuser lengths are supplied in sections for butt jointing on site. (Alignment plates supplied) Ceiling height 2.7m, increase throw by 1m for each 1m increase in ceiling height. Horizontal diffusion is based on a cooling differential of 11 C. Vertical projection is based on a heating differential of 11 C. Noise level is based on diffuser sound power level less 8dB room absorption.

43 High Capacity Swirl Diffusers SDFCH / SDICH / SDACH The Waterloo SDFCH is a high capacity fixed blade swirl diffuser designed to produce a horizontal, radial air pattern with a turbulent, high entrainment jet characteristic and is ideally suited for applications with high heating or cooling differentials. The Waterloo SDICH is based on the SDFCH but allows the individual adjustment of blades to create a specifically required air pattern. The Waterloo SDACH is also based on the SDFCH but provides adjustment to the angle of all of the blades in unison in order to create the required air pattern. This can also be controlled remotely with an optional motor. Both the SDICH and the SDACH allow a continual adjustment from providing coanda effect to vertical dumping. They are particularly useful in areas that experience a varied thermal load, for example areas that are effected heavily by the changes in season. All products in the high capacity swirl diffuser range are suitable for ceilings up to 1m.

59 Supply Air Nozzles EBD Waterloo EBD supply nozzles are capable of delivering air to spaces where long distance penetration and low noise levels are required. Suitable for cold and warm air supply applications, these versatile adjustable units are ideal for providing focussed ventilation or where precision is required. When grouped, penetration can be considerably enhanced. EBD supply nozzles are made of pressed and spun aluminium, painted RAL 9010 % gloss as standard although other colours are available upon request. Available in 7 sizes to suit standard duct dimensions. EBD s are manually adjusted to their chosen position, although a motorised option is available. Adjustment of up to 30 from the major axis is possible.

60 Supply and Exhaust Valves VA / VAF / VB / VBF / VC A range of high quality valves for supply and exhaust applications for commercial and industrial projects. Series V valves are best applied to air distribution systems handling relatively low air flow rates within small circular ductwork. The valves provide high initial resistance with wide throttling capability which is necessary to offset the relatively high system resistances. VAF and VBF are passively protected for 60 minutes against the spread of fire. Product Description VA Supply valve with spindle locknut VB Exhaust valves with spindle locknut VAF Fire rated supply valve with spindle locknut VBF VC Fire rated exhaust valves with spindle locknut Exhaust valve with tamper proof screw locking of inner core Installation All units are supplied with a steel mounting subframe which should be fixed to the prepared opening. Cut aperture to suit subframe size shown in table below Screw subframe into aperture Offer valve body into subframe and rotate into bayonet fixing Valves can be made tamper proof with the addition of a lock nut on either side of the rear bracket. Standard - polyester powder gloss white VC and VCF valves are only available as RAL 9010 Gloss Throw is the radius of diffusion (V t = 0.2 m/s) (Supply valve VA/F only). P s is the static pressure loss (Pa). Noise level is based on diffuser sound power level less 8dB room absorption.
