Abstract
For an inside to outside dust collector, a self tensioning bag retainer for connecting the upper end of a fabric sleeve filter to an overhead support. For preinstallation of the filter assembly, a compressed tensioning spring is retained from movement by a pin member to facilitate ease of installation. With the pin member removed, however, the spring acts upwardly against a retainer cap to appropriately tension the sleeve filter and to permit controlled flexure during cycling from a filtering to a cleaning operation.
