Evac Optima 5
Advanced vacuum toilets

The Evac Optima 5 is the quietest vacuum toilet on the market according to independent research. It uses our proven pneumatic flush mechanism, with flush memory and vacuum sensor technology.

With the Evac Optima 5 there are no overflows or unflushed toilet bowls caused by a temporary loss of vacuum – the control unit with flushing memory ensures that there is sufficient vacuum for flushing before allowing the flush to be performed. Both the water consumption and flushing time can be adjusted.

The seat can withstand weights of up to 280 kg and is resistant to cigarette burns and scratches. For improved hygiene and upon request, the Evac Optima 5 is also available with antibacterial seat material to provide extra protection against a wide range of bacteria.

The Evac Optima 5 vacuum toilet is available in floor and wall-mounted models and in urinal. We also offer special auto-flush and fire-resistant versions.

Benefits

  • The quietest flush operation on the market
  • Hygienic, durable, and compact design
  • Low fresh water consumption (1.2 l/0.4 gal. per flush)
  • Reliable operation with flush memory and vacuum-guard technology
  • Easy to clean and maintain

Evac Optima 5 urinal

 

The Evac Optima 5 urinal is the world’s first and only vacuum urinal. It is compact, using an integrated vacuum mechanism in the bowl rather than a vacuum interface tank. It is available in auto and button-flush versions, as well as a waterless version. The flush in the Evac Optima 5 vacuum urinal is much more powerful than that of traditional gravity urinals, meaning that all of the water is changed completely, while the waterless version removes urine completely. This means no deodorizer block is needed with either version, as urine traces and odors are eliminated.

The Evac Optima 5 vacuum urinal is also available with USPH certification. The Evac Optima 5 urinal consumes only 0.6 l/0.2 gal. per flush.

Operating principle of Evac vacuum toilet

Pushing the flush button sends an air pulse to the control mechanism that connects the vacuum to the water and discharge valves. The water valve opens and lets rinsing water flow into the bowl through the flushing ring. After a short delay, the discharge valve opens and the contents of the bowl are discharged into the vacuum sewer. The control mechanism then closes the discharge valve and, after a short delay, closes the water valve. The delayed closing of the water valve ensures that a small amount of water remains at the bottom of the bowl. The toilet is then immediately ready for the next flush.

The Evac Optima 5 vacuum toilet is highly economical, consuming up to 75 percent less water per flush than a traditional gravity toilet – 1.2 l/0.4 gal compared to 4.5–9 l/1.2–2.4 gal. The Evac Optima 5 is also more hygienic as it effectively removes contaminants, mist, and odors from the bowl rather than allowing them to escape into the surrounding atmosphere.

The operating principle of the Evac vacuum toilet system couldn’t be simpler. Instead of relying on traditional solutions that use gravity to remove waste and which are heavily reliant on the location of services cores and outgoing sewer connections, the Evac system flushes the toilet by creating a powerful vacuum. Pushing the flush button sends a pneumatic signal to the control mechanism, which opens the discharge valve by allowing vacuum from the piping system to enter the discharge valve diaphragm, connecting the bowl to the vacuum system. Air at atmospheric pressure then forces the sewage through the discharge valve and into the piping. The water valve opens at the same time and pressurized rinse water cleans the bowl. The whole operation is performed using just vacuum, with no electrical connections required.
