Compare source machine ratings of55L/min and75L/min against transport requirements and site conditions.
Compare machine flow ratings first
Both petrol models are rated at 150 bar (15 MPa). The J-1555L offers 55 L/min and the J-1575L 75 L/min. Assess 75 L/min where supply and drainage support greater sediment transport. Check whether 55 L/min meets routine flushing requirements.
Keep single-lance records separate from machine ratings
For the J-1555L, nozzle, regulation and supply conditions for the earlier single-gun figure of 150 bar (15 MPa) and 35 L/min need confirming. Use 55 L/min for the machine-level figure. Verify tool flow individually, including on the 75 L/min J-1575L.
Compare adjacent models for different pressure requirements
Consider the 200 bar (20 MPa), 50 L/min J-2050H for higher jetting pressure. Compare the three machines against deposits, pipe material, water supply and waste removal. The ten-nozzle flushing assembly is optional on the J-1575L. Specify accessories per machine.

Comparing J-1555L and J-1575L — questions
What does this article address?
Compare source machine ratings of55L/min and75L/min against transport requirements and site conditions.
What site information is needed before equipment selection?
Provide area, aisle width, floor/pipe conditions, contamination, frequency, power/water, city and budget range.
After reading “Comparing J-1555L and J-1575L”, is a site trial still needed?
This article offers selection guidance. For complex sites, heavy contamination or continuous work, verify models and configurations through equipment information, video or a trial.
