A properly sized and manufactured bellmouth is critical to reaching an engine’s required performance parameters during test. For over forty years, Atec’s engineers have employed the latest design and analysis tools to develop inlet bellmouths that meet the OEMs air flow requirements.

We provide build-to-print services for clients across a broad range of Inlet styles and materials.

Our traditional mesh screens are precision-welded and fitted to eliminate stress tears or openings, as well as foreign object debris (FOD) risks. Additionally, advanced low turbulence screens employing 3D printing, waterjet, and laser cutting manufacturing meet the most demanding intake requirements.
