HIGH AIR FLOW LINEAR SLOT DIFFUSERS KLN
SERIESOVERVIEW
CHARACTERISTICSAPPLICATIONS
installation in continuos lines
OVERVIEW :The KLN series linear diffusers allow to manage high air flows with minimum pressure losses and generated noise power.They allow to fully make us of the induction principle, guaranteeing optimum comfort conditions, no noticeable air currents and temperature uniformity, even in large areas by positioning the diffusers along the perimeter of the ceiling.
The big innovation on the KLN series is the double flow deflector system: for horizontal throw 2 settings are available and fully adjustable on constrcution site.The first setting allow supply air horizontally with a big ceiling effect, while the second setting still allow horizontal air supply but for biggest air flow and low pressure loss and noise level.
CHARACTERISTICS AND OPERATION :The KLN series diffusers are constructed from an aluminium diffuser body lots and a series of deflectors, also in aluminium, for the horizontal or vertical air though. The change of direction of the air through can be easily made without removing the diffuser.
APPLICATIONS : The KLN series diffusers are ideal in application with a ceiling height between 3 and 6 meters like open space offices, commercial galleries hospital wards or hotel rooms.
VERSIONS : Standard, with or without filter holderFineline, with or without filter holderFitted, without filter holderWith panel, with or without filter holder
DIFFUSER INSTALLATION: The KLN series diffusers are installed inside special plenum boxes, by suspension using quick fix connectors. This solution allows a quick installation even at the end of work carried out on the building site. Possibilty of installation in continuos lines.
FINISH : The KLN diffusers are constructed from an aluminium body anodized or painted white RAL 9010.The deflectors cam be anodized, painted white RAL 9010 orblack painted. The KLN diffusers with panel are constructed from an aluminium body and a carbon steel panel .Special finishes for the diffuser body can be made on request.
UNSUITABLE ENVIRONMENTSThe aluminum products are not suitable for installation in environments with an atmosphere containing corrosive substances for this material and in particular containing chlorine, such as swimming pools, spas and some types of food industries.

AIR THROW ADJUSTMENT
CHOICE OF AIR THROW ORIENTATION :The horizontal throw represents the most common use of this type of diffuser, both for heating and cooling. The throw follows the ceiling and expands horizontally within the room. This generates a vertical recall of air present in the room, guaranteeing a perfect mixture of air without the presence of air currents within the occupied area.The vertical throw, used when heating, allows to send the hot air directly within the occupied area to hinder the formation of layers of hot air in higher parts of the room caused by the lesser density.The change of orientation of the air throw is obtained by rotating the deflector blade from an inclined position to a horizontal one, and vice versa. The blade is rotated from within the diffuser, with the use of a leaver at both extremities of the air slot.

CAUTIONS FOR VERSIONS WITH PANEL
Never apply forces of any kind on panel, this may imply panel deformation. The weight of the panel itself, of the diffuser, of the plenum box and of the air duct has to be supported by plenum box hangers and not by the panel.Always handle with care. never lift or handle the product using the panel. To lift or handle the product please hold the plenum box body.The manufacturer does not assume any responsibility in the event of uncorrect use.
