Compare machine flow and site needs without transferring accessories between models.
Compare machine flow at the same stated pressure
Both machines are rated at 150 bar (15 MPa). The J-1535L delivers 35 L/min and the J-1555L 55 L/min. For routine sediment, check whether the lower flow suffices. For sustained removal from a main drain, verify supply and discharge capacity at the higher flow.
Verify power and accessories for each model
The J-1535L uses a Lifan petrol engine. Confirm the J-1555L engine specification separately. Both have a single standard gun. An earlier J-1555L single-gun figure of 150 bar (15 MPa) and 35 L/min requires confirmation of the test conditions. Confirm optional flushing heads, surface cleaners and rotary nozzles against the order.
A35L/min figure needs its operating context
J-1535L's35L/min is a source machine rating. J-1555L's historical35L/min single-lance record still lacks nozzle, regulation and water conditions. Equal figures do not establish equal machine capability, configuration or two-lance output.
Select against actual site information
Record pipe dimensions, bends, deposits, water/return conditions and any surface task. A larger rating is not automatically needed for a light short branch. Confirm special attachments and multi-operator requirements separately.
Checks after reading
- Site area, routes and narrowest access
- Floor, dust, oil, debris or pipe-blockage type
- Daily frequency and continuous working time
- Power, water, wastewater, consumables and service conditions

J-1555L versus J-1535L: matching55L/min and35L/min to the drain task — questions
What does this article address?
Compare machine flow and site needs without transferring accessories between models.
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 “J-1555L versus J-1535L: matching55L/min and35L/min to the drain task”, 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.
