Design
The VVKR-F is made from galvanized steel sheet with powder paint surface finish. It consists of the backing box with
circular duct connection equipped by rubber gasket and the front plate with adjustable polymer deflectors. The outer
shape of the backing box fits into T-bar ceiling frames with raster 600 mm or 625 mm. The front plate holds in the
backing box by simple hinges on one side and by spring fixing brackets on the other side. The front plate can be
opened or detached easily without tools. To prevent the free fall of the front plate during manipulation on the diffuser
a safety string connects it detachably to the backing box. For easy opening of the front plate without tools there is a
folding ear on the edge of the plate.
