63-5643-16 ［Discontinued］Hand blower wind changer ECO -808 ECO-808
Features
- Correspondence to the Course of Study "3rd Year of Elementary School: Science A: Materials and Energy ・・・: How the Wind Works": Docodemo Experiment Without Power Supply! You can experience actions and results together! A wind changer is a device that creates wind by rotating a handle.
- If you replace the handle with three insertion ports with different gear ratios, there will be air flow.
- You can use a sailing wheel to compare how things move when you change the air volume.
- When children create their own power (wind power), they feel a deeper sense and understanding of the experiment.
Spec
- Airflow: 3 levels (low, medium, strong)
- Dimensions: width 280 x depth 100 x height 315 mm (depth 160 mm when handle is mounted), fan 3 blade diameter/190 mm
- Weight: 1010 g
- For safe use
- At the "strong" level, it's designed to be 1 rpm basic with the included handle. Spin faster than that, and you'll be more likely to hear noise, slip gears, and so on.
- Experiments at the "strong" level should be performed at 1 revolution per second.
