Compressed air is mixed with the cleaning liquid using a pressure intensifying device (2) and a valve (3), the mixing being controlled using pressure regulators (8-10), in order to increase the pressure of the liquid being passed through the pipe or hose (7) being cleaned. This compressed air supply is then later used to expel any liquid left behind, initially using the pressure intensifying device and then finally both compressed air and liquid are removed via a valve (16). |
