Product Description
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 DRL 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. While normally used for horizontal distribution, the diffuser may also be used for vertical projection if required.
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 for 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.
Motorised Operation
To satisfy the demand for remote automatic operation, a motorised version of the Model DRL is also available. The cylinder drum is motorised to alter the air discharge angle for heating or cooling modes. Cylinder travel can be altered to suit on site requirements, by adjustment of the motor. Internal air pattern vanes are manually adjusted to the required position.
The builtin motor mounting assembly is suitable for 275 high diffuser sizes only
