Create the right airflow with minimal ventilation

The BL 4500 is a side air inlet with a unique V-shaped flap that creates a jet stream with more mass. This gives the incoming air a longer throw, which allows the air to warm up better.

The unique V-shape of the flap of the BL 4500 side air inlet creates a jet stream with more mass.

The BL 4500 black line side air inlet is available 2 versions: self-opening and self-closing. With the self-closing version, you have even better control over the minimum ventilation with the 1 in 3 system.
