Mainstation, Hybrid

The Hybrid Mainstation is a complete hygiene station offering all the required functionalities for professional cleaning of exterior surfaces in the Food & Beverage industry.


Nilfisk FOOD Mainstation Hybrid operates in three modes allowing rinsing, foaming and disinfecting of the cleaning areas. Integrated in the block patent pending Corona Technology injects air into the water stream over a bigger surface and at a higher speed, resulting in better mix of air, compound and water that generates approx. 20% more foam. 

Thanks to the integrated water outlet it can be used effectively as a standalone cleaning station, but it can also be equipped with additional satellites allowing max. 4 simultaneous users on one unit.
The Hybrid main station is smart and self-protecting as it has an integrated dry run protection and automatic turn-off mode, after a specific periof  of inactivity (that is defined and programmed by the customer).
The unit is also energy efficient thanks to the configuration possibility of the water pump.

Unique features
Corona Technology​

The CoronaTechnology air system – patent pending – is a completely new construction that sets standards within the cleaning industry. Thanks to this system the air is injected into the water stream over a bigger surface and at a higher speed. The result is a better mix of air, compound and water that generates approx. 20% more foam.
DuoFoam Technology​
The new injector block has the capacity for two different compounds at only one outlet, which makes it very easy and safe to change from one product to another. Patent pending.
MIX, Double Injection Technology
The unique system is prepared for the injection of an extra booster compound
into the DuoFoamTechnology block, which takes the cleaning effect into a whole new level.

    3. Press the "left arrow" button and at the same time turn on the main power to the cleaning station (Do the two actions at the same time)

    4. The problems is resolved now; the display is in the "normal mode" and should charge the internal battery

    5. To test: After 15 minutes try to switch off the main power and wait for three minutes, then turn it on again. If the problem is not solved, it means that the display is broken/dead.
