Description
The VX is our own NACA duct, a take on the classic NACA submerged intake. We designed it with CFD (computational airflow simulation): the side walls curve and widen along the ramp so they form a vortex pair that draws air in, and the ramp entry and lip are smoothly rounded. At the back, a round hose spigot with a clip ridge lets you run ducting straight to where you need the air.
Each one is printed to order in the UK in UV-resistant ASA, with a matte charcoal finish.
