In-line operation
The device uses the water line's existing flow rather than a separate treatment cycle.
The BeLife product familyOne in-line system.
One in-line system.
Multiple scales.
BeLife is installed in the water line and uses Fuji Keiki's CORE WITH HOLES negative-pressure design to generate ultrafine bubbles through rotation and pressure change in the flow.
Model family
U.S. nominal sizes from NPS 1/2 through NPS 3.
Eight Fuji Keiki models cover applications from a single fixture or compact branch to larger building mains. Final size and connection details are confirmed during pilot engineering.

U.S. sizing note: U.S. NPS sizes lead throughout this table; A-series model names are retained as published by Fuji Keiki for technical traceability. NPS values are nominal-size equivalents for orientation—not dimensional, thread, flange, or connection guarantees. Final model and connection details must be confirmed during pilot engineering by Fuji Keiki and a qualified plumbing professional.

How the device works
Engineered flow geometry—not chemical dosing.
Water passes through Fuji Keiki's internal CORE WITH HOLES geometry, which introduces rotation and pressure change. Under the documented test conditions, downstream water contained ultrafine bubbles measured with NanoSight instrumentation.
The illustration explains the published generation principle. It does not claim a guaranteed outcome in every water system.
No added treatment chemicals
Bubble generation comes from the internal flow geometry—not chemical injection.
No filters or cartridges
The device is designed to operate without routine filter or cartridge replacement.
Installation scale
Choose the point that defines the downstream scope.
Install BeLife for one room, a plumbing branch, or a building main. A qualified plumbing professional confirms the appropriate line, connection, pressure, space, and local requirements.
Localized scope
One room or fixture group
Install on the branch serving a defined restroom, laundry area, treatment room, or specialty cleaning zone.
Department scope
A plumbing branch
Treat the water distributed to a department, floor, restroom bank, or operational area from one accessible line.
Building scope
The incoming water main
Position at the appropriate building entry point so downstream outlets receive water that has passed through BeLife.
