The Black Line Ceiling 4000 air inlet is a high volume air inlet with a good insulation rating. The BLC 4000 is a self-opening air inlet. The BLC 4000 has an extended flap. This flap directs the air horizontally a longer distance. Ideal when the air inlet is located above cages. For barns where air needs to be sent along both sides, you can choose the double air inlet vent BLC 8000.
The BLC 4000 is made of 20 mm foam. This gives both the flap and the frame a high insulation value.
Ensure 100% closed flap in closed position.
