摘要:
A vacuum hose handling and safety vacuum release system, a tubular column attachable to an industrial vacuum hose end having a long handle and a short T-handle positioned at right angles to each other that will allow a user to strategically place the metallic vacuum tube conveniently and easily to vacuum debris in a safe manner. The tube has at least one bypass orifice that the user can open to reduce or eliminate the suction at the nozzle via a lever pivotally located adjacent the T-handle.
