Abstract: A venturi incorporated in a pneumatic tube conveying system for flexible textile fabrics such as uniforms and table linens handled in commercial laundries. The venturi includes an angled pipe which joins the main piping system at an acute angle and which receives air from a blower. An inside pipe is installed within the main piping to create a restriction at the connection of the venturi with the main piping.
