The Black line Tunnel inlet can be placed as a standalone air inlet with a flange around it. Or as a tunnel inlet simply placed on top of each other and connected.

Tunnel inlet with 8% more air output

BT stands for Black line Tunnel inlet. This is a tunnel vent made of PU foam. The BT series is a standard side vent with flanges around it. These are glued together to form a tunnel inlet. You can connect and fine tune the vents very easily.

The Black line Tunnel inlet is available in a self-opening and a self-closing version.

A special fine tuning knob makes it very easy to adjust the vents to each other. The pull force has also been optimized: a five-louver tunnel requires a 16 kg force. And with its aerodynamic design, this vent gives 8% more airflow.

The Black line Tunnel inlet is available in 2 versions: self-opening and self-closing.

The self-closing version has the advantage that the flaps are always completely draft-proof in the closed position.
