Collection – Vacuum Toilet System

Evac offers vacuum collecting units for all types of vessels, from yachts to cruise liners and naval installations.  Evac vacuum collecting units create a powerful vacuum and are optimised for each application.  The units have been designed to work reliably under heavy duty conditions and to bring energy saving benefits. They are designed for installation as part of the chain that makes up the waste water collection and treatment system onboard vessels.

Evac offers a variety of vacuum toilets for different applications. Typical features include a water-saving flush, elegant design, reliability and low sound level in use.  Toilets are available in porcelain and in robust stainless steel, and the range includes shock tested navy and squatting toilets. Interface valves are available to connect gravity lines to the vacuum piping system.
