S Series Low-profile
Vacuum Generator (model LPVG)As the most versatile, efficient and quiet vacuum sources
developed by Dometic, J series vacuum generators offer
boatbuilders more reasons than ever to install premium
VacuFlush toilet systems. Along with the most efficient waterand power consumption, they operate much more quietly thanmacerator toilet motors, and can be configured to most any
marine plumbing application.

Where space is limited, this low-profile unit is the perfectfit. Provided as a single unit, the whisper-quiet pump andsturdy polyethylene tank can also be installed separately
for unique applications.
