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.
