The cylindrical radial flow diffusers JPK-KS are usable in large halls with heights of up to 30 m and were designed to discharge air carrying materials such as aerosols, steams and abrasive dust from working areas. The jet directions can be seamlessly adjusted from horizontal to vertically downwards. The diffuser consists of a cylindrical body with a conically tapered perforated diffuse basket with a floor panel including prepared attachment points for optional suspension brackets. The jet adjustment is done motor-driven by moving the interior steering cone.
