The CVA type diffusers are designed for ceiling applications. They can be used for supply air in heating and cooling.
These diffusers have adjustable blades. For supply air purposes, they are characteristically suitable for horizontal and vertical air throws. These diffusers are recommended for use with ceiling heights up to 7 m. with a supply air temperature difference of -10ºC / +15ºC. If the diffuser face is installed more than 300 mm below the ceiling, then it is possible to have continuous throw angle adjustments between the vertical and the horizontal. However, if the diffuser face is close to the ceiling, then only a vertical or a horizontal throw setting is possible.
