Easily move fume hoods around your science classroom on Air Science USA's Purair Carts. These epoxy-coated steel carts serve as a base for the 24-inch-, 36-inch- or 48-inch-wide Air Science Purair 5 ductless fume hoods. Three side panels ensure your fume hood stays put, and casters (two locking) make it simple to position the unit at just the right angle for experiments. Store small supplies on the convenient lower shelf.
