The VacuFlush 140 series (EcoVac) offers a space-saving design with

adult-sized seat. All come with an attractive, easy-to-use flush pedal that

also locks open during tank discharge.
Medium-height 140 series toilets are available in three discharge

models: a rear discharge unit, a right-side discharge unit, and a left-side

discharge unit.
VacuuM holDinG TanK (VhT)
The VHT4500 produces and stores vacuum between flushes.

The vacuum pump draws only 3 amps of electrical current

at 12 VDC. The VHT contains a pressure differential switch

that deactivates the pump when the proper level of vacuum is

generated.
The VHT system is equipped with “3/4-full” and “full” level float

switches. The “full” float switch is wired to an automatic shutdown

relay that prohibits the vacuum pump from generating vacuum

once the tank is full.
