Design
Linear slot diffuser HELLA is manufactured from aluminium profiles. The surface treatment can be anodized aluminium
or powder paint. The number of slots can be 1 up to 4. Each individual slot is equipped by longitudinal deflector, which
can be adjusted for different air flow patterns in 180° angle between the vertical and two opposed horizontal
directions. These deflectors as well as the profiles dividing the slots are dismountable without tools, making so the
installation of the diffuser easy. The galvanized steel slider adjustment damper as a part of the diffuser can be
attached or detached without tools. The end caps (frame profiles on short sides of the diffuser) are fixed by screws. If
the end caps are dismounted, it is possible to install a continuous array of multiple diffusers. Galvanized steel plenum
box with circular duct connetion can be delivered as accessory of the diffuser optionally with insulation inside/outside.
For installation without plenum box a galvanized steel mounting bridge is available.
