The Waterloo small format continuous slot diffuser seriesCS has for many years set the industry standard in termsof highest aerodynamic and acoustic performance. TheCS range is ideally suited to variable volume applicationsdue to its excellent low flow rate air diffusioncharacteristics and high air handling capacity. The novelair pattern control element design allows any air diffusionto vertical projection, without any change in the facialappearance.CS diffusers are suitable for all commercial and industrialprojects requiring single or multislot diffusers for ceilings,bulkheads or sidewall supply and exhaust.Diffusers are manufactured from aluminium alloyextrusions fixed or clipped to cross stays allowing easyremoval of internal vanes and pattern control elements.

IntroductionPlenum ChambersLinear Diffusers
InstallationThe plenum boxes and neckreducers are supported by 4 droprods through a locating holepositioned near each corner.When ordering plenum chambersplease specify length width &height, spigot size and position(top or side entry) and controloptions. Please note that theplenum height should in general be100mm greater that the spigotdiameter (side entry applications).
Correct selection and sizing of distribution plenum chambers andneck reducers is critical because terminal air resistance is very lowrelative to the distribution ductwork resistance. It is thereforerecommended that whenever possible terminals are served by lowvelocity stub ducts from branch ductingbalancing
systems fitted with correctcontrols.
Where it is necessary to specify and use plenums, a generous allowancefor commissioned noise generation should be made. A similar effectresults from use of neck reducers with circular duct connections becausethe reduced duct area will cause generally higher velocities and henceincreased risk of noise generation.

Aircell Diffusers
The unique integrated design of the plenum, damper anddiffuser assembly has been specifically developed topromote smooth flow lines, ensuring an exceptionalaerodynamic and acoustic performance.Aircell products can be used in any air distributionsystems where temperatures do not exceed 50° C.The components have been tested to BS4773 Parts 1 & 2to provide comprehensive, easy to use selection data forall installation options.
The ‘O’ series opposed blade damper is designed tointegrate with the plenum and diffuser range to provide asimple means of flow regulation from the diffuser face.
The unit is designed to snap fit into the universal plenum,or alternatively can be easily screw or rivet fixed intosteel ducting using the inbuilt mounting lugs.
Manufactured in black engineering grade polymer, thedamper is inherently smooth and positive in operation.
The ‘P’ series plenum is aerodynamically profiled toprovide ideal flow conditions with either top or side entryduct arrangements.
Manufactured in black engineering grade polymer, thedesign incorporates features such as internal guide vanesto reduce air turbulence, and snap-in locks to retain theopposed blade damper and diffuser mounting bar.
The plenum can be fixed to the ceiling grid or suspendedby drop rods from the slab. Either fixing method iscarried out using patented mounting brackets whichsimply slide into the plenum retaining slots.
The R600 snap-fit neck reducer is available as an optionto convert the P600 plenum spigot from 397 Ø to 312 Ø .

This can also be controlled remotely withan optional motor.Both the SDICH and the SDACH allow a continualadjustment from providing coanda effect to verticaldumping. They are particularly useful in areas thatexperience a varied thermal load, for exampleareas that are effected heavily by the changes inseason.

The Waterloo MC diffuser has been designed forboth supply and exhaust applications requiringcompact circular diffusers; unlike conventional highaspiration diffusers the MC has a small overall toneck size ratio. The diffusers are adjustable toproduce horizontal or vertical air patterns.
The MC diffusers are constructed from steel spinningsretained on aluminium spider braces.

Introduction
WFORT WFOVT WFOIT WFORS
The Waterloo Aircell WFO series floor diffuser offers thechoice of horizontal or vertical air patterns with its flipover design, as well as a host of other unique & patentedfeatures. The WFOV low pressure vertical supply discoffers vertical projection with a 50% increase in airvolume capacity, compared with standard WFOR units.
The WFO diffuser discs are 200mm Ø and it has beendesigned to resist permanent deformation when subjectedto point loads up to 500 kg and all materials used are fireretardant. The WFOV diffuser disc is suitable for pointloads up to 300kg.

Hi-Flo Jet Diffusers
The Waterloo RWH diffusers have been designed tohandle high air flow rates and provide relatively longthrows which make them particularly suitable forconditioning of large spaces such as halls, auditoria,terminal buildings, warehouses and factories.The diffusers are versatile in application by virtue ofthe novel “reversible and rotatable” core designwhich allows the air jet to be adjusted for bothpattern and deflection. Units may be mountedindividually or in banks, in bulkhead arrangements ordirectly into stub ducts.The diffusers are constructed from aluminiumspinnings supported on a studding and spacerassembly. The core may be rotated through 180° toexpose either a straight or diffused core assembly. Inaddition, the diffuser spigot may be rotated within themounting plate (if supplied) to enable a full 360°adjustment, by releasing the tension bolts.
RWH Complete diffuser assembly including diffusercore, spigot and mounting plate (wall orceiling mounting).
RWH-P Diffuser core and spigot only (suitable formounting onto bulkheads or stub ducts thuseliminating the large mounting plate).
• Simple and effective air diffusion for large spaces• Long throw characteristics• High air handling capacity• Easy to install and adjust• Reversible core to produce long throw jet or short
throw diffuser patterns• Core rotatable through 360° for “eyeball” jet
direction• Jet may be deflected off axis by up to 15°• Available in four sizes• Multiple outlet arrangements

A range of high quality valves for supply and exhaustapplications for commercial and industrial projects. SeriesV valves are best applied to air distribution systemshandling relatively low air flow rates within small circularductwork. The valves provide high initial resistance withwide throttling capability which is necessary to offset therelatively high system resistances.All valves are constructed from steel spinnings protectedby a polyester powder gloss white finish. Flanges arefitted with sealing gaskets and all units are supplied asstandard with plated steel mounting subframes.
All units are supplied with a steel mounting subframewhich should be fixed to the prepared opening.•• Screw subframe into aperture• Offer valve body into subframe and rotate into
