Abstract: An ergonomic sander handle for clamping onto a sanding device so that the ergonomic handle can be comfortably gripped by a worker and used to apply the sanding device to a surface, is provided. The ergonomic handle includes an elongate body, a clamp head and a bearing. The elongate body is typically a cylindrical aluminum tube with padding for easy and comfortable gripping. One end of the elongate body is attached the clamp head that attaches to the sanding device. The other end of the elongate body is attached to the bearing which may include a pair of roller balls. To sand a surface, the worker grips the elongate body in a power grip (without significant wrist flexion or deviation) and applies pressure to urge sanding device and the bearing onto the surface. The power grip minimizes loads on the wrist and hand which reduces the likelihood of musculoskeletal trauma.

Abstract: A low-noise air delivery system including a nozzle plate having a plurality of tubes. Each tube acts as an independent nozzle with an external diameter (d). Each tube is spaced approximately two external diameters (2d) apart from an adjacent tube. The system also includes a hand-held portion coupled to the nozzle plate engageable to and in communication with an air supply.
