The development of the 6000-series comes from the projection of our tunnel inlet units.
By producing these inlets without top or bottom flange, they can easily be built together to tunnel ventilation units. Units build from 2, 3 or 4 elements (6000-VFG-2, 6000-VFG-3 and 6000-VFG-4). These inlets also are executed with a curved inner flap and divided air directions on the top and bottom side. This makes the individual air inlet valves also suitable for the regular ventilation systems. The large width of the inlet however makes the control of the minimum ventilation more difficult; making the inlet less suitable for for example broilers. The execution with the central control arms makes the individual inlet better controllable.
