Specifically for tunnel ventilation or additional frontage ventilation, we have developed a large version of the Twin called the Twin tunnel inlet.
These tunnel inlets are always installed in groups of 2, 4 or 6 inlets. This creates large inlet openings that provide the optimum cooling effect at maximum ventilation. The Twin tunnel inlet seals hermetically and is well insulated.
The Tunnel Flex is designed for sandwich panels and has a shallow build-in depth. The Tunnel Twin has a minimum installation depth of 200 mm.

Twin tunnel inlet installation dimensions
Twin tunnel inlets are essentially placed like Lego blocks. Each flap is 1000 mm wide and 500 mm high. In this way, together they form a large inlet opening in the wall.
