Evac stainless steel Vacuum toilets

Our stainless steel vacuum toilets operate in the same way as equivalent porcelain models. These durable units are ideal for navy or other vessels where there are high demands on equipment.

The Evac stainless steel toilet was originally developed for military use. It is equipped with the proven, fully pneumatic Evac discharge valve and mechanism, with flush memory and vacuum sensor technology. It is also available with optional shock and vibration protection.

Operating principle of Evac stainless steel toilets

The flush button sends an air pulse to the control mechanism, which connects the vacuum to the water and discharge valves. The water valve opens, letting rinsing water flow into the bowl. After a short delay, the discharge valve opens and the contents of the bowl are discharged into the vacuum sewer.

The control mechanism closes the discharge valve and, after a short delay, the water valve. The delay ensures a small amount of water is left at the bottom of the bowl. The toilet is then immediately ready for the next flush.
