EVAC Bus Vacuum Toilet

Clean. Comfortable. Superior

System Design

Saving space as well as resources, this microprocessor-controlled, all-in-one unit features a local vacuum system, removing the need for a vacuum-proof waste water tank. Perfectly adapted to the requirements and high standards of modern bus travel, the EVAC Compact Bus system brings the superior technology and unrivalled experience of the world’s leading manufacturer for on-train hygiene systems to bus enviroments.

Well-established in more than 80,000 applications world-wide, Evac’s vacuum technology has many advantages over the chemical toilet solutions still found in many bus cabins. Clean, comfortable and eco-friendly, the Evac Compact’s sealed waste-water system keeps odors safely away from the cabin and removes the need for chemicals – while at the same time saving precious water. Like all Evac systems, it is easily adaptable to different cabin designs and can be implemented with a wide range of seat variations.
