- Central Vacuum Dynorbital Supreme includes low profile, premium urethane weight-mated sanding pad. Has 1″ outside diameter vacuum port, for easy connection to central vacuum system.3/32″ (2.5 mm) diameter orbit.
- Dynorbital Supreme models run at 12,000 RPM. Rotor utilizes five blades and produces more useable power. Composite rotor is stronger and has better lubricating qualities, enabling blades to last longer.
- Composite base has integrated rubber over-mold creating a non-slip feel, as well as insulating from cold. The air motor is suspended by vibration-absorbing rubber rings (Patent No. 5,319,888) to minimize vibration.
- Triple-sealed front double row balancer bearing (Patent No. 4,854,085) is guarded from sanding residue for long life and lower maintenance; easy replacement using 57098 Repair Kit.
- Anti-clog design (Patent No. 5,319,888) enhances the vacuum pick-up on central vacuum models. Dust particles are directed away from the air motor (reducing contamination) following a smoother, easier path of extraction. Comfort Platform provides additional hand and wrist support, further enhancing operator comfort. Also offers increased protection against cold air exhaust. (NOTE: Comfort Platform is removable.)
