Nozzle Diffusers Description CAP-C is a multi-nozzle diffuser with a plenum box, mainly intended for air supply in comfort ventilation systems for offices, shops, medical rooms, school classrooms, etc., installed in open space under the ceiling.
/ 16 | Nozzle Diffusers Design The CAP-C body is made from galvanized steel, composed of the plenum box with a sidewards oriented rubber gasket sealed circular connection and diffuser plate with polymer nozzles, attached by permanent magnets. 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.
