Evac Optima 5S vacuum toilet The ultra-silent next generation member for Evac´s vacuum collection solutions

The Evac Optima 5S is the next generation, ultra-silent vacuum toilet. The noise level of flush operation, 66db(A), is up to two times lower compared to other solutions on the market. The significant noise reduction will make visits to the toilet much more pleasant.

With the Evac Optima 5S 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.

In addition to featuring a new silencer technology, hygienic matters have been improved with new sealed seat cover. An antimicrobial seat is also available on request providing extra protection against a wide range of bacteria.


  • New ultra-silent solution – quietest flush operation on the market with only 66db(A).

  • Low fresh water consumption (1.2 l / 0.4 gal. per flush for wall and floor models, and for 0.6 l / 0.2 gal. for the urinal).
  • Reliable operation with flush memory and vacuum-guard technology.
