Abrasive blasting cabinet for fine dental finishing work - has plastics supply pipes threaded through flexible protective pipe to facilitate replacement and attached to separating wall.

摘要

The abrasive mixture supply pipe (53a) runs in a protective flexible pipe (83). This runs from the bottom chamber (81) to a processing chamber (31) which are separated by a sheet-metal wall (59,179). The protective pipe has long sections which bend or fold and the abrasive supply pipe is made of flexible material, pref. plastics, and is movable within the protective pipe. The protective pipe is attached to the separating wall (59) by being screwed onto an armature. ADVANTAGE - Worn feed pipes can quickly and easily be replaced by threading the pipe through the protective pipe.
