Evac OnlineFlex

The Evac OnlineFlex uses robust mechanical components to create and maintain constant vacuum in a vacuum toilet system without the need for intermediate tanks. The design is based on the operating principle of a rotary pump – the same concept as the familiar roots blower used in air compressors.
