They provide the most effective means of releasing the arch for the most demanding materials (e.g. coal, slag, sawdust...). Within a split second, the air cannon releases the accumulated content of compressed air, the air flows through the outlet pipe of a large diameter, and its stroke disrupts and releases the blocked material. The outlet pipe is welded onto the tank at an angle so that the gas can flow in the direction towards the storage tank discharge.
Each cannon is fitted with a valve and the control unit can activate the assembly so as to release the arch in a fast and effective way.
