Centralized vacuum system NettoTram®
NettoTram® is a revolutionary SEFAC system that can be used to vacuum clean the inside of urban rail vehicles sus as metros and trams. In less than 2 minutes, NettoTram® enables dry cleaning of waste such as paper, dust, packaging and newspapers. It provides an outstanding result in a very short time!
NettoTram® is secured to the floor. A compensating bellows, secured to the main unit is applied to one of the vehicle’s doors, the other door remains open to suck the air from the vehicle by creating a powerful airstream between the front and rear doors of the vehicle (thus covering its entire internal surface). This suction is generated by two propeller fans, each driven by a motor (located above the main unit). The air extracted from the vehicle after filtering is released outside through a chimney.
The return on investment is guaranteed before the first two years of use.
Our SEFAC experts are available to discuss your NettoTram® implementation project.
