Dual and Hi-Lo lances that switch between high and low pressure at the lance. A Hi-Lo lance lets the operator drop to low pressure to apply detergent and go straight back to full pressure to rinse, without walking back to the machine. On any job with a chemical step that is the difference between a fast wash and a slow one.

Choose by length and by the maximum pressure and flow your machine produces. Where a lance is offered in several nozzle sizes, the size sets the flow the lance is matched to - too small and you will build pressure and stall the flow, too large and you will lose pressure at the nozzle. If you are not applying chemical through the lance, a single lance is lighter and cheaper.
