Radial Fan Test Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14186

Overview

The Radial Fan Test Apparatus is designed to study the operating behavior, performance characteristics, and efficiency of radial (centrifugal) fans under controlled laboratory conditions. It allows students to analyze the relationship between flow rate, pressure difference, power consumption, and efficiency for fans with different blade geometries.

Radial fans are widely used for transporting gases at moderate pressure differences. The air enters axially at the center of the fan impeller, is redirected by 90°, and exits radially. The experimental setup includes a radial fan driven by a three-phase AC motor with variable speed control via a frequency converter.

Transparent intake and delivery ducts allow direct observation of flow patterns. A throttle valve at the delivery side enables controlled variation of airflow, while interchangeable forward-curved and backward-curved rotors make it possible to compare the effects of blade geometry on fan performance.

Pressure, temperature, and flow rate are precisely measured using an integrated microprocessor-based data acquisition system, with optional software for visualization and analysis via USB connection. Comprehensive instructional material is provided for experiment setup, execution, and data evaluation.
