ButlerBuilt Transparent NACA Air Vent, Ø76 mm

The ButlerBuilt transparent NACA air vent is designed to draw in outside air and direct it into Ø76.2 mm (3") aeration ducting. Its teardrop-shaped NACA shape allows for discreet integration into the bodywork or onto the glass of a race car.

Its transparent plastic construction makes it particularly suitable for integration into Lexan or polycarbonate windows. It can thus be installed on a side or rear window to create an air intake while maintaining a clean, seamless appearance.

This NACA air vent can, in particular, supply air to a sheath designed for brake cooling, an oil cooler, or cockpit ventilation. Depending on the chosen installation location, it can also be used to channel fresh air to the engine intake.

With sizes of approximately 266.7 mm in length and 152.4 mm in width, it offers a large intake surface area while retaining the characteristic profile of a NACA air vent. The rear connection is designed for a sheath with a diameter of 76.2 mm.

This transparent ButlerBuilt NACA air vent is sold individually.
