Abstract (en)
[origin: EP2080566A1] The device has a hose (3) connected with an input port of an air-cleaning nozzle body (4). A connection is provided for a compressed air source, where the nozzle body has radially acting nozzles (8) distributed around the circumference of the body. The nozzle body has an even front surface (7) at an end that is turned away from the hose, and the nozzles are arranged directly adjacent to the even front surface. The nozzle body is designed in a rotationally symmetrical manner. An independent claim is also included for a method for cleaning boreholes.
