Abstract

The present invention relates to an air cannon (100) that comprises a pressure container (102) for pressurizing gas, an outlet (104), a fracturing member (122) arranged in the outlet (104), wherein the fracturing member (122) breaks when the pressure in the pressure container (102) exceeds the breaking point of the fracturing member (122).
