To satisfactorily supply a large volume of air into big open spaces such as shopping malls, leisure arenas and gymnasiums, requires a certain type of diffuser. This type of application is where the design features inherent in the Model CJD are best demonstrated.

With adjustable vertical vanes located in a rotational cylinder drum, the diffuser is capable of supplying controlled ventilation over a long throw in both heating and cooling modes. Whilst normally used for horizontal distribution, the diffuser may also be used for vertical projection if required.


Outer flanged frame mitred with corners mechanically cleated. Cylinder drum, adjustable vanes joined by mechanical fittings.


The diffuser is constructed from aluminium extrusions and incorporates a flanged frame for easy installation. A polypropylene bristle is used to seal the cylinder drum inside the outer flange frame. With the diffuser in-situ the cylinder is able to rotate a full 360 degrees, to allow cleaning with or without an OBD fitted.
