This model uses an insulation tube to protect the belt, but the pulleys, the belt and the combs are accessible for inspection, cleaning or adjustment at both the top and bottom ends of the tube, aming it ideal for educational displays and demonstrations. The belt is a long lasting silicone rubber and both performance and reliability is excellent.
Should repair be required, or you are conducting an off campus demostration, the whole instrument can easily be dismantled down to the components to reduce size for transport and reassembled.
