摘要

A modular device for cleaning textile and metal filter elements in dust separators by blasting with compressed gas comprises an annular expansion chamber (19) between a blast pipe insert (2), a pressure reservoir (1), a membrane valve (3) and a valve cover (4). The flow cross-section of the expansion chamber is at least equal to that of the blast pipe insert.
