— FAQ
You may also be interested in J-3515D
Make judgment based on the tasks, configuration, and usage conditions of this model.
Can a 35 MPa pressure level effectively remove all buildup?
No. The result depends on the surface, soil, nozzle, working distance and operating conditions. Identify the material and carry out a test clean first.
What are the restrictions to consider before part washing?
First confirm the coating, precision surface, sealing, and water-proof areas, and do not equate the cleaning of the exterior with the internal parts or electrical component cleaning.
How should comparison be made with J-3522D?
Respectively verify the pressure rating, flow rate, and on-site water supply, with a focus on determining the differences between localized rinsing and the task of removing a significant amount of residual dirt.
Can the storage tank or heat exchanger be used directly?
No. Judgment cannot be based solely on the model. Restricted spaces, residual media, and equipment requirements need to be assessed separately. Do not consider surface operation diagrams as permission for internal operations.
What documents should be provided during selection?
Cleaning object, surface material, dirt, no-water areas, working distance, water supply and drainage conditions. For electric solutions, check the on-site power supply.
