Reinforced PVC (polyvinyl chloride) duct hoses are used for moving large volumes of air in chemical fume-removal, general fume-removal, and solvent-ventilation applications in the food-manufacturing, chemical-manufacturing, pharmaceutical, industrial woodworking, and plastics-processing industries. These hoses can also be used for low-vacuum applications on dust-cleaning equipment. These hoses resist damage from chemicals and moisture, and they are made from transparent material that lets users see what's in the tube. The hoses are highly compressible, which saves space when transporting them.
