Duct AC Training System
✅ Description
The Duct AC Training System from Atto Labware demonstrates the working principles of centralized duct-type air-conditioning systems commonly used in commercial buildings.
The setup enables learners to analyze airflow distribution, static pressure, cooling performance, and duct design with practical fault-finding exposure.
