Abstract
A turbine-driven sander includes a relatively thin, one-piece resilient dust shroud having a skirt surrounding a sander housing. The skirt has a rear wall which is split to form two opposing end portions, which are releasibly connected at an integral joint. The skirt has a front wall including a nozzle cover portion, and a pair of side walls having inwardly-extending lips. When attached to the housing the skirt sealingly engages the housing and creates a passage for dust-entrained air to flow from a platen to the nozzle. The air then flows to the turbine, eventually being exhausted into a source of vacuum.
