1 Linear diffusers 1 / 1 KSV Slot diffusers Ordering code Number of slots Diffuser Length (mm) KSV Description KSV is an air terminal element primarily designated for air supply. It is suitable for installation into ceilings or into walls. The installation of this slot diffuser is possible with plenum box or without it, using a mounting bridge. Color of deflectors Diffuser construction Surface finish Black White * NOTE: For corner decorative pieces it is not neccessary to indicate slot length in the Ordering code. Example of the ordering code: KSV B - - A Complete unit incl. side frame at both ends End unit for linear assembly Middle unit for linear assembly Corner unit * Anodized aluminium finish RAL91 white Diffuser with slots, 9 mm length, black deflectors, mounting bridge, complete unit incl. side frame at both ends, anodized aluminium finish. B W E M C A RAL91 Highlights: long impact high induction direction set up by adjustable deflectors narrow construction comfort design modularity 1 to slots on diffuse available The way of air direction is set up by changing the inner deflector position. This deflector has alternative positions for different air flow patterns (horizontal left/ right, diagonal left/right and vertical) see Fig.. Besides these basic positions it is possible to set the deflector into mounting positions, which are used for mounting KSV to the plenum box or mounting bridge or for adjustment of the plenum box regulating damper. Information about accessories for KSV is available on page 1. KSV-MB - Mounting bridge PB-KSV - Plenum box

2 / 1 Linear diffusers Design KSV is made of extruded aluminium profile with elox surface and the inner part of the slot is plastic. Plenum box of the slot with both socket and regulating damper are made of galvanized steel sheet. Plenum box can be supplied with sound attenuating material from the inner side (code 1) or thermal insulating material from outer side (code J). 1 Fig. 1: Air flow visualisation Fig. : Different deflectors setup and resulting air flow patterns Product parts & setup possibilities: 1.

Ordering code example PB-KSV I Plenum box for double slot diffuser KSV, 9 mm length, internal isolation. * NOTE: If no isolation defined in the ordering code, the plenum box comes without isolation. Design KSV-MB is made from galvanized steel. It has a rivet nut to catch the fixing thread bolt of the diffuser. Description The plenum box PB-KSV dimensions are adjusted the size and number of slots of the diffuser stated in the box ordering code. Design PB-KSV is made from galvanized steel sheet, equipped by duct connections with gasket. The air flow volume can be adjusted by damper at the box connection. The box can have isolation from inside and from outside

The plenum box has eyelets for hanging under ceiling. KSV can be installed without plenum box as well, directly in opening of suspended ceiling. The mounting bridge KSV-MB is used to hold the diffuser connected by thread bolt in the diffuser slot.
