FM-1849-38 Radial Fan Flow Apparatus 

The FM-1849-38 Radial Fan Flow Apparatus is a laboratory system designed to study the performance, characteristics, and flow behavior of radial (centrifugal) fans. It enables users to explore how airflow, pressure, efficiency, and velocity distribution vary under different operating conditions.

The unit consists of a motor-driven radial fan with adjustable speed control, allowing precise variation of impeller rotation. Two interchangeable impellers are included—one with forward-curved blades and another with backward-curved blades—so that users can compare their performance and efficiency characteristics. The impellers can be replaced easily, facilitating quick experimental setup.

A transparent intake and delivery pipe system provides clear observation of airflow patterns and ensures stable flow conditions during operation. Airflow is regulated using a throttle valve located at the outlet, enabling controlled adjustment of flow rate and pressure.

The apparatus is equipped with integrated sensors to measure key parameters such as airflow rate, differential pressure, temperature, and rotational speed. These measurements allow detailed analysis of fan performance, including efficiency and characteristic curves. When used with compatible data acquisition software, results can be visualized graphically, making it easier to interpret trends and record accurate data.
