Product Details

This apparatus is designed to study the performance characteristics of an industrial axial fan, allowing students to measure the relationship between flow rate, pressure head, input power, and overall efficiency. It provides a practical method for generating the characteristic curve of fan and analyzing how variables like speed and intake restriction affect its operation. The unit features a bench-top setup with an axial fan mounted between inlet and outlet ducts, each equipped with pressure and temperature sensors. Speed of the fan is variable, and a manually controlled louvre at the intake allows for precise adjustment of the airflow rate. All measurements, including flow rate, pressure differential, and temperature, are displayed on a built-in LCD and can be transferred to a computer for detailed graphical analysis and calculation of efficiency. Its primary application is in mechanical engineering education for teaching fluid mechanics and turbomachinery principles. The key benefit is the hands-on investigation of fan performance, enabling students to plot characteristic curves, understand the impact of system resistance, and calculate efficiency, which is essential for the selection and application of fans in HVAC and industrial ventilation systems.
