Air Duct Apparatus | PolarX - 576
Product Overview
The Air Duct Apparatus PolarX - 576 is a realistically scaled ventilation training unit for studying fluid mechanics, airflow, and multi-duct system balancing. This Air Duct Apparatus features a forward-curving variable speed centrifugal fan (0.75kW, up to 890Pa and 0.8m³/s) discharging into 200mm dia. galvanized steel ductwork with at least 6 balanceable air supply locations. Measurement tools include a combined vertical/inclined manometer, pitot static tube, and digital anemometer (range 0~30m/s). Optional LABVIEW-based DAQ software supports automated data measurement.

Construction and Design
The Air Duct Apparatus PolarX - 576 features a rectangular air inlet and filter holder, together with a forward-curving variable speed centrifugal fan and integral control console. The fan discharges directly into a 200mm dia. galvanized steel duct connected to the distribution ductwork. Main components include T-branch, straight length, parallel duct, 45°, 90°, and 180° bends, down bend, air handling unit, active damper, pitot tube, and multiple diffuser types. All ductwork and components are constructed from galvanized steel. All rotating components are covered when the filter and holder are in position. The stand uses 24 gauge iron.
