We manufacture a high-quality laminar flow canopy to maintain a secure environment that provides a grade 100 cleanroom and highly efficient H14 HEPA filter for processes and products without incurring the additional costs of upgrading the entire room. It includes a housing, pre-filter, fans, and variable speed controllers. The system offers a vertical air supply and an average wind speed of 0.37 to 0.4 m/s, which has a noiseless performance.
