Description The air diffuser type ZMD is an air diffuser for universal use in all mounting situations. Owing to its infinitely variable adjustment from long-throw to wide-angle diffusion, it is universally suited to ventilate all types of rooms, particularly high-ceiling halls, rooms with considerable heat generation, behind raster ceilings, etc. Suitable for all air-conditioning systems. Installation is possible in any ceiling construction. The ZMD diffuser head has several rows of apertures, arranged in a specific relationship. The front apertures can be completely or partially closed by...

ZMD air diffuser Models and dimensions Minimum setting Air throw pattern Wide angle setting Adjusting disc Long throw setting Standard setting: maximum To reduce the flow rate, i.e., increase the pressure loss, by means of the nozzle, the diffuser head can be slid towards the rear, by loosening the slotted screws on the side, until the upper row is covered (minimum position). The volumetric flow can be determined, as shown in the pressure loss diagrams, by means of a static tube. Increase of noise due to the damping should be taken into consideration. In the long throw position, the...
