Emergency Verification | Can Pumice Floating on Water Be Removed Using Only Compressed Air as a Source?

Sanwa Enterprise Co., Ltd. has released a video verifying whether it is possible to transport and remove floating pumice using the air tool "Conveyor Bag," which operates solely on compressed air as its source.
The Conveyor Bag does not use mechanical components such as fan motors and can operate using only compressed air. Since there are no obstacles in the flow path, it can easily suck in water and debris without any issues, leading us to explore its potential for removing pumice that is covering the seas of Okinawa and causing damage.
▼ What is the Conveyor Bag?
With the keyword "just connect compressed air," it is one of Sanwa's pneumatic devices that has been chosen in manufacturing sites for nearly 40 years. By simply connecting compressed air, it generates a powerful vacuum and is applied for air transport.
▼ Usage examples
- It can suction, transport, and discharge not only gases and powders but also metal fragments and steel balls used for shot blasting.
- Since it has no moving parts and does not use electricity at all, it is effective for transporting and exhausting dangerous gases or mists.
