Product Details

This apparatus is designed to study the performance of two axial fans operating in series, allowing students to analyze how this configuration affects total pressure development, flow rate, and overall system efficiency compared to a single fan. It provides a practical method for understanding the principles of staged compression in fan systems. The unit is a self-contained, bench-top system featuring two industrial axial fans mounted in series within a duct. The system includes inlet and outlet ducts equipped with pressure and temperature sensors, and a manually controlled louvre at the inlet to vary the airflow resistance. The speed of each fan can be controlled independently or together, and all operational data is displayed on a built-in LCD, with the option to transfer data to a computer for detailed analysis and plotting of characteristic curves. Its primary application is in mechanical engineering education for teaching fluid mechanics and HVAC system design. The key benefit is the comparative analysis it enables, allowing students to measure the combined performance of fans in series, understand the trade-off between pressure and flow, and grasp the practical implications for designing ventilation systems that require higher pressure capabilities.
