Released a video of the Silent Vacuum Drainage System.
The Silent Vacuum Drainage System is... When installing toilets or similar facilities in basements, it is common to use a pressurized system with a sewage tank and a sewage pump to pump up the wastewater. However, a minimal amount of wastewater often remains in the sewage tank, leading to unpleasant odors. Additionally, when trying to install toilets or water facilities in existing buildings, it can be difficult to secure the usage conditions of the lower floors and the slope of the drainage pipes, which may lead to abandonment of the project. To address these issues, a vacuum-based drainage system has been developed as an alternative to the pressurized system. However, many existing systems apply vacuum sewage systems that use lift-up methods and gas-liquid mixed suction, which can cause noise and vibration issues. This system is a Silent Vacuum Drainage System that can eliminate noise and vibration problems by using a method that does not involve air suction. Model units are available for viewing.
