DF-47-NARROW

DF-47-NARROW (-S) high induction linear diffuser for medium-to-long throw

DescriptionHigh induction linear diffuser for medium-to-long throw, DF-47-Narrow model, with length L mm and slot H mm for air flow.Allows ±30º vertical turn of core (linear nozzle), due to a narrow slot that makes it possible to cover medium and long throws, achieving comfort with both cooling and heating and providing an excellent aesthetics.They are suitable for both ceiling and wall installation. Particularly appropriate for variable air volume, although the design allows excellent operation with constant air volume as well.

ApplicationThese medium-to-long throw diffusers are very appropriate in cases that require a long-distance air jet or a medium-distance air jet with low sound levels.They are especially indicated for commercial facilities, mezzanines, shops, residences, etc.This diffuser is suitable for both supply and return. High-quality aesthetics and performance are further enhanced by alternating the return diffusers with supply diffusers in the same continuous line.

FinishesManufactured entirely of extruded aluminium sections.The unit can include a directional (RFS06) volume control damper and plenum box of galvanized steel sheet (internally insulated (-PFA) or uninsulated (-PF)). There are two types of plenum box: fixed or detachable.If a plenum box is included, a volume control damper can be included in the connection inlet, annulling the RFS06 damper.

In the DF-47-Narrow-IC and DF-47-Narrow-CC models, the frame or duct is constructed of galvanized steel and the diffuser is made of aluminium.

Standard finish in anodized or painted in RAL-9010 glossy white.

Operating mechanisms and mountingThe mounting systems available for the diffuser element are shown in detail on page 5.The diffuser is specified by the slot length and slot width. The -MT motor-driven mechanism moves the nozzle in the vertical direction (up and down) at an angle of approximately ± 30°. The required motorization is provided by one motor per diffuser, even in groups containing several units. Thermal self-adjustment is also possible.

Hidden high induction linear diffuser for medium-long throw DF-47-NARROW-LT

DescriptionKoolair hidden high induction linear diffuser for medium-long throw, model DF-47-NARROW-LT: length mm; air flow slot of mm.Characterised by the lack of profile on show. Its narrow slot allows medium and long throw air distribution, providing comfort when supplying either hot or cold air, while having a very pleasing aesthetic appearance.Designed for installation in both ceilings and walls.

UseThese medium-long throw diffusers are perfect for installations which require a jet of air to be supplied over either long or medium distances at low sound levels.They are especially suited to commercial premises, mezzanines, shops, homes, etc.This diffuser can be used for both supply and return air. Installing supply and return diffusers alternately in one continuous line ensures a high level of aesthetics and functionality.

FinishesMade entirely from extruded aluminium profiles.Option to be supplied with regulation damper (RFS06) and galvanized sheet steel plenum (with (-PFA) or without (-PF) internal insulation). Where a plenum is included, there is an option for a regulating damper on the spigot instead of the RFS06 damper.Standard finish painted in matt RAL-9005.
