The hoses are full vacuum and semi-corrugated in order to have a better bending radius. The standard range of diametres is from 8” up to 12” in tailor made solutions, lengths normally go from 5.3 m up to 11 m, both with and without soft ends.
The heavy duty aspiration hoses are with smooth lining and stronger service and are used for cleaning streets, construction sites, rail-tracks, in situations of earthquakes and flooding.
