The inexpensive but nevertheless high-quality solution to create a better growth climate in the greenhouse with little effort!

With the advantages of EC motor technology and the newly developed long-throw rectifier for hitherto unattainable values for horizontal throw!

With the Doll injector on the discharge side, which was developed in the flow laboratory, the HV 5000 systems combine two previously contradictory properties: a high throw distance on the one hand and a homogeneous width and height flow on the other. Conventional fans on the market with a large throw distance have a very strong centric horizontal flow that "shoots" through the culture like a laser beam. with corresponding plant production disadvantages. The Doll injector also injects lateral air layers and avoids a strong centric flow. The HV 5000 is available in two versions: as an inexpensive version with an AC motor and as a top-premium version, the HV 5000 EK with the Doll high-efficiency EC motor. This combines the technical ventilation and cultivation advantages of the Doll injector nozzle with the energy efficiency benefits of EC motor technology!
