CSF (RS1)Linear slot diffuser

FunctionCSF (RS1) linear slot diffusers are designed for cooling or heating in standard office height of min 2.5m to 3.5m. Ideal supply temperature to ambient should not exceed 10K to ensure low terminal velocities in the occupied zone. Exceeding these guidelines can result in draft in occupied zone or stagnant heated air below the ceiling. CSF (RS1) slot diffusers have deflectors which been designed to have non-vision construction. These deflectors are as standard black and slide from left to right easily to assure a good air outlet pattern adjustment.

DesignCSF (RS1) slot diffusers are manufactured from profiled aluminium and have as standard black deflectors and hit and miss damper in galvanized steel. Slot diffusers are painted to RAL 9010 as standard. Available on request in anodized aluminum satin finish.

MountingSlot diffusers contain a mounting bridge as standard which can be mounted directly inside the duct, or to be easily mounted to the plenum box.

Optional extraInsulated and non-insulated plenum box.

CSFHigh profile linear slot diffuser

Features• High air handling capacity

• Wide dynamic range for perfect VAV systems

• Strong Coanda effects for good low flow performance

• Fully adjustable air pattern from horizontal to vertical

• Hidden flow control vanes for consistent facial appearance

• Continuous joint detail for ceiling integrations.

SpecificationLinear slot diffusers shall be CS-F incorporating two flow control vanes fixed to a central pattern control element on each slot. The air pattern shall be adjustable from horizontal to vertical without changing the appearance of the diffusers.

Flow Control VanesStandardDiffusers are supplied with flow control vanes in lengths up to 750 mm (to suit diffuser length).

SpecialTo provide finer control of the air pattern, flow control vanes may be supplied in any specified lengths.

IntroductionThe continuous slot diffusers series CSF has for many years set the industry standard in terms of highest aerodynamic and acoustic performance. The model CSF range is ideally suited to variable volume applications due to its excellent low flow rate air diffusion characteristics and high air handling capacity. The novel air pattern control element design allows any air pattern to be produced from 2 way horizontal iffusion to vertical projection, without any change in the facial appearance. CSF diffusers are suitable for all commercial and industrial projects requiring single or multislot diffusers for ceilings, bulkheads or sidewall supply and exhaust.

Description : ManufactureDiffusers are fabricated from high grade aluminium alloy extrusions fixed or clipped to cross stays allowing easy removal of internal vanes and pattern control elements.

SizesStandard - from 1 to 8 slots wide. - 1800mm long (excluding ends) - continuous diffuser lengths are

supplied in sections for butt-joining on-site. (alignment strips supplied).

Special - multi-slot diffusers, (i.e. more than 8 slots) mitred joints and ceiling integration schemes up to 1800mm long refer to us.

FinishStandard:Epoxy Polyester Powder Coated off white/pure white.Other powder coating finishes available on request.

DSLLinear diffuser for continues ceiling application

IntroductionLarge format linear diffusers are ideal for most commercial supply and exhaust systems and integrate well with ceiling tile and lighting layouts. The clean design provides an extremely low air resistance characteristic and this makes the diffuser ideal for any fan coil or induction system which is pressure sensitive. Single or multislot diffusers are available with fixed 1 or 2 way air patterns; multi-slot 2 way diffusers may be adjusted to suit site conditions by changing vanes. Pattern control vanes may be easily removed for installation, access or cleaning. A range of plenum chambers to suit DSL diffusers is available as an option.

Description : ManufactureDiffusers are constructed from high grade aluminium alloy extrusions fixed or clipped to cross stays. Internal vanes are removable for installation purposes.

TypesDSL - One way dischargeDSL-D - Two way discharge

SizesStandard - Single or multislot.

Standard length = 1200mm (For site butt joining).Shorter Modular lengths to suit.

Special - multi-slot diffusers, (i.e. more than 8 slots) mitred joints and ceiling integration schemes up to 1800mm long refer to us.

Features• Ultra low pressure loss characteristics suited to fan coil

and induction supply systems.

• Single or multislot to suit most air handling requirements.• Clean design for practical integration with lighting or ceiling

systems.• Fixed 1 or 2 way pattern to prevent unwanted adjustment of air

diffusion.

InstallationStandard fixing for 2 to 8 slot diffusers is by means of mounting brackets which are fitted into plenum chambers (or hemmed ducts). After removing the inner vanes the diffuser is raised up to the fixed plenum chamber or duct through the ceiling opening and fixed to the mounting brackets with screws provided; this system allows for a tolerance of 25mm between duct and ceiling levels. Finally replace inner vanes. Continuous diffusers are supplied with alignment strips for each vane and frame section.
