Nilfisk-ALTO upgrades of the successful NEPTUNE medium and premium range lines of hot water professional pressure washers.
The new NEPTUNE 4 FA and NEPTUNE 5 FA are equipped with a hot water version of the new NA5 pump. This pump, already present in a cold water version on the POSEIDON 5, is a 3 ceramic piston wobble disc pump, driven by a 1450 rpm motor.

The new NEPTUNE 7 FA line is equipped with the wellknown C3 pump technology for superior durability. In addition, all 3 hot water models are equipped with a flow activated system – a further development on the old 02 and C3 KEW systems. The flow activated system uses the movement of water in order to generate the start and stop impulses to the motor.
Compared to the pressure activated system, the new solution offers several advantages:
- Absence of stand-by pressure in the hose, gun and lance during by-pass. Hoses etc become more maniable, easy to move and safe.
- Low sensitivity to leaks in equipment, components or piping. Leaks that would generate motor start-stops on pressure activated systems will not cause these problems on flow activated systems – thus preserving motor life.
As on the pressure activated systems, pump head is not under pressure and simplicity and ease of service are good.
The terminology “FA” in the product name will indicate that the unit is equipped with a flow activated system.
Other features:
The NEPTUNE line retains all of the well-known and highly competitive features that have been important in ensuring the success of these ranges in the past years.
- Time delayed auto start stop for extended motor reliability (and increased user comfort through no noise during work pauses)
- Flame sensor
- Exhaust gas temperature sensor
- Low fuel safety to protect fuel pump
- Duo motor system ensuring good burner function irrespective of phase connection
- EcoPower boiler
