A C B + D Description is a rectangular linear diffuser in aluminium. is suitable for both supply and exhaust air. is equipped with air guide baffles, making it possible to use for horizontal supply air. Both ends are equipped with flanges. The horizontal dispersal pattern can be easily changed without the use of tools by turning the air guide baffle. The air guide baffle must be removed for vertical supply air. can be supplied in two versions, or, depending on capacity requirements or aesthetic considerations. can be installed with plenum box STB/STU in order to achieve an even flow and individual adjustment. Slot width: A No. of slots 0 Cutout: A + x + B 0 C D is normally supplied in lengths up to max. m, but can be supplied on request up to m. MTZ- is a 0 o joint, when an aesthetically pleasing corner is required. Discrete appearance Used for both supply air and exhaust Horizontal and vertical supply air.

Accessories MTZ- B + Installation in plenum box STB/STU A self-tapping screw is fitted through the slot up into the perforated surface of the plenum box. B + Installation of slots in continuous strips MTZ- B MTZ- B 0 MTZ is supplied as two mitred ends (not one piece). The slots are often installed in continuous strips, where there is a need to join the slots, so that it resembles a single piece. In these cases, the full length must be specified when ordering, and the slots will be supplied adjusted to the total length. The outermost pieces will be equipped with end pieces, and the middle pieces will be supplied without end pieces. The slots are joined using the accompanying pins.
