CTA drum diffusers are designed for use in wall and ceiling applications. They can be used for supply air in heating and cooling.
The diffuser construction permits warm or cool air to be thrown to long distances. The throw characteristics are suitable for constant or variable volume systems. The diffuser can be rotated 30º above and below its neutral axis, so it is possible to use with heating and cooling, by changing the diffuser throw angle. In addition, there are individually adjustable deflector blades inside the drum, to deflect air both sideways. The drum can be rotated manually on with an actuator.
