This drum sander rental has a one-horsepower constant-speed motor and a soft rubber drum that combine with Essex's unique cam locking system to work like a professional sander. The sandpaper is held between two spring-loaded cams. The slow (1,800 RPM) constant speed of the drum will not gouge floors. The tilt action of the SL-8 allows for more controlled and even sanding when comparing it to other machines available to the rental trade. When you sand forward and backward with the SL-8, you can be assured of straight sanding because it is propelled by the drum and wheels. The weight of this hardwood floor sander rental is specifically designed and evenly distributed for the best results. Gap Power supplies all your sandpaper for floor sanders.
