Centrifugal Blower Apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-CELE-14156
Overview
The Centrifugal Blower Test Apparatus
is a comprehensive and self-contained experimental unit designed to
study the performance characteristics of a centrifugal blower (compressor)
under varying flow rates, pressures, and speeds.
The setup allows measurement of important
parameters such as suction and delivery pressures, blower speed, power
consumption, and air flow rate, enabling students to evaluate performance
curves, efficiencies, and operating behavior.
The system features complete
instrumentation, optional computerized data acquisition, and PID-based
SCADA control, ensuring high accuracy and real-time analysis for both
academic and industrial training environments.
