Ventilation Demonstration Apparatus, 8.7 x 6.5 x 4"

The Eisco Labs Ventilation Apparatus is a large-size demonstration tool measuring 8.7 x 6.5 x 4 inches. It is designed to demonstrate conventional movements in heated air, based on an early method of ventilating mine galleries before the invention of electric motor-driven fans. The apparatus also demonstrates the function of domestic chimneys when used with open fires. It is a practical visual learning tool for physics and environmental science classrooms, where understanding of convection currents and air circulation is a learning objective.
