Abstract
A sander vacuum housing and pad frame system is provided for generating unique, continuous air flow for dust collection in a sander coupled to a dust collection system, while providing the versatility of a pad frame system. The system has particular application to a pad frame system for supporting sanding pads having varying characteristics, but is not limited to such a system. The system comprises a vacuum housing configured to be coupled to a motorized sanding mechanism of a sander for moving the vacuum housing in a sanding motion. The vacuum housing defines the upper portion of a dust channel. The dust channel in the vacuum housing is configured for connection to a dust collection system. The system further comprises a pad frame configured to be coupled under the vacuum housing for moving the lower surface of an attached frame in a sanding motion. The pad frame comprises a sanding pad for supporting sandpaper. The vacuum housing defines air flow dust ports, which may be proximate the upper surface of the attached pad frame in a lower portion of the vacuum housing. The dust ports permit a continuous flow of air during dust collection from a region outside the vacuum housing proxi…
