• Flexibility in Design - Wastewater can be lifted vertically
up to 20' from point of collection. Essentially eliminates the need for
piping under the floor within the building.
• Small Pipe Diameters
(1-1/4" to 4") - Minimize installation costs, maintenance costs,
and future modification costs.
• Overhead Piping Installations – Allows
for added accessibility of the vacuum drainage system. Future modifications
are easily accomplished.
• Vents & Traps May be Eliminated -
AIRVAC Vacuum Interface Valves provide a positive seal between discharged
wastewater and the lavatory, water fountain, or other fixture.
of Service and Changing of Valves -Valves may be changed or serviced
with the transport system in operation.
• Water Conservation -
AIRVAC Vacuum Toilet uses 2/3 gallon (or less) of water per flush.
Elimination of Pipe Obstructions- Wastewater is transported at 15-18'
per second. Possibility of bacterial growth is drastically reduced.
Treatment Costs - Multiple collection tanks / discharge pumps can be
used to separate different types of wastewater. Also optimizes re-use
of non-contaminated wastewater streams.
• Transportation of High
Solid-to-Liquid Ratios - The system is able to transport wastewater with
high solid-to-liquid ratios
