Le BL4500 dirige l’air avant que celui-ci arrive dans le bâtiment.
Create the right airflow in minimum ventilation
A conventional air inlet creates in minimum setting a long narrow opening. Therefore, the incoming fresh air has little mass, decreases in speed too rapidly and drops down to early on the animals.
The BL 4500 inlet has a V-shaped flap. The V-shape bundles the incoming air, creating a jet stream for more mass and therefore a better throw of the incoming air.
The self closing variant has the advantage that you can make a delayed opening system e.g. 1 in 3 inlets open first. Together with the a jet-stream valve one can have total automatic control over the minimum ventilation.
The Black line 4500 air inlet is made of high quality polyurethane foam with a high insulation value.
