The external design of the Neptune 4 hot-water
high-pressure cleaner is identical to the Neptune 3
line of products. As far as sensors, control,
functionality and electronics are concerned, there
are no differences to the Neptune 3 series as well.
There are only two differences compared to
Neptune 3:
The Neptune 4 series has the NP5 hp-pump (1)
installed (like the Neptune 5) and the machine is
equipped with an additional hydraulic accumulator
(2)(see also STI MPW-040).
For further details about the construction of the
machine, refer to the Neptune 3 and Neptune 5 / 7
Service Manuals (chapter C resp. chapter 3).
