Nozzle Diffusers | 3 / 20 Description CAP-F is a multi-nozzle diffuser with a backing box, mainly intended for air supply in comfort ventilation systems for offices, shops, medical rooms, school classrooms, etc., installed in T-bar false ceiling. Highlights • Versatile adjustability of air discharge patterns • Excellent air induction and mixing even with small air flow volumes, fit for VAV ventilation • High air flow capacity with low noise and moderate pressure drop • Compact design Fig.
/ 20 | Nozzle Diffusers Design The CAP-F body is made from galvanized steel, composed of the backing box with a vertically oriented rubber gasket sealed circular connection and diffuser plate with polymer nozzles, attached by spring clips. The nozzles can be rotated by 360° in the plane of the diffuser plate The proper directional adjustment of the individual nozzles results in the desired air discharge pattern.

/ 20 | Nozzle Diffusers Accessory THOR Plenum Box Description The THOR plenum box is used together with air diffusers for pressure reduction, airflow balancing and sound attenuation as well as for measuring and adjusting the air flow. The plenum box can be used for air inlet and extract. Design THOR plenum boxes are manufactured from hot-dip galvanized sheet steel with inlet connection sleeve fitted with a rubber seal tested for air-tightness.
