Air Duct Training System | PolarX – 580
The Air Duct Training System PolarX – 580 examines air distribution methods using a variable, trainee-built duct configuration on a mobile-frame radial fan (1.5~1.75kW, up to 1200m³/h). This Air Duct Training System includes pipe bends, branches, reducers, and 3 types of 180° bends in DN100, DN80, and DN-50 diameters, along with throttle valves and iris diaphragms for flow control. Measurement tools include U tube, inclined tube, and digital manometers, pitot tubes, and an anemometer, covering pressure range -25~25kPa and velocity range 0.25~30m/s. A switch cabinet with fan speed control and a dedicated storage box complete the system.
The Air Duct Training System PolarX – 580 examines different ways to disperse air within a structure using a variable, trainee-built duct configuration. This Air Duct Training System is used to study ventilation systems found in offices, sports arenas, production halls, conference rooms, and other spaces.
Product Overview Ventilation systems typically include additional features for conditioning the air in the room, in addition to the air duct system itself. Filters and other components for sound absorption or air purification might also be present. A fan with a speed controller supplies air to the air duct system in this Air Duct Training System.
Using commercial parts including pipes, disk valves, bends, branches, and filters, the trainee builds variable air duct systems. Connections for measuring pressure can be placed anywhere in the system. The impacts of each component on pressure loss, and consequently on the air’s velocity and flow rate, are examined. Two manometers with varying measuring ranges and a manual air velocity measurement instrument are available for this purpose. The fan’s characteristics are also ascertained, and its power consumption is quantified.

Construction and Design
The Air Duct Training System PolarX – 580 uses a radial fan mounted on a mobile frame to connect the air ducts. The duct system is built from pipes with pipe bends, joints, and components in varying diameters, including DN100, DN80, and DN-50. Three types of 180° bends, sharp, short, and long, are available, along with different types of elbows and iris diaphragms. Pitot tubes are placed on different pipe diameters to measure air velocity, and pressure measuring connections can be positioned at variable locations. A switch cabinet houses the fan speed control, and a P&ID diagram represents the full air duct system layout. A storage box keeps all parts organized in a single place.
