The highly cleaning efficiency here is based on the pneumatically driven rotation of the nozzle carrier head and of the lance pipe. Mechanical and hydromechanical effects work hand in hand in an ideal way at operating pressures up to 3000 bar. The 1 - 6 metre variable lengths of the lance pipes enable you to also clean longer pipe lengths. The guns also work at high efficiency in other ranges using a variety of applicable nozzles. In addition, these can be fitted with a radio remote-control or optionally available as EXI version. Applications with hot water up to 100°C can be carried out at any time. The Eco Top Drill is especially suitable as an accessory for WOMA devices in the Advanced and Expert series.
