Wafer Fab Turbine Exhaust Diffuser from Japan
Custom diffusers recover pressure from high-velocity turbine exhaust while maintaining laminar flow in semiconductor cleanrooms, preventing particle re-entrainment. HTS 8411.99.90 as other gas turbine parts for wafer manufacturing facilities. Aerodynamic design minimizes turbulence near processing tools.
