Ravo, which is part of the international Fayat Group, is a Dutch company with more than 50 years of experience in the development and manufacturing of vacuum street sweepers. These vehicles are sold worldwide, so you probably already saw one of their machines cleaning your street.

An important component of a street sweeper is the fan that creates a low pressure inside the machine, in order to remove all kinds of garbage from the streets. Ravo wanted to know if there were still possibilities to improve the design of their fan, which is already used for many years. They also wanted to know if the same performance could also be reached with a modified design that would fit better into the available spaces inside the vehicle.
