The CDB type variable throw air diffuser is designed for ceiling applications to achieve the different throw characteristics required in heating and cooling of spaces automatically.Due to the fact that cold air tends to go down, and warm air tends to float; it is necessary that air is supplied horizontally when cooling, and vertically downwards when heating. The diffusers are intended for supply air usage, together with the acessories required for various demands.
These diffusers have straight profile blades.The diffusers are recommended for use with ceiling heigts up to 5 m.with a supply air temperature difference of -10 / +15ºC. The diffuser is made of a frame and a central blade block. The blade block is free to move up down inside a frame which can easly be removed / installed for access to the damper above (if present). With this termostatic diffuser, when the supply air is cool (<22ºC), the air stream is thrown horizontally and when it is warm (>29ºC), it is thrown vertically downwards, by the moving of the blades. The movement is performed by a thermostatic element inside the diffuser and no manual or electrical power or adjusments are necessary. The standard production is in 4-way square pattern only.
