Create a particle-free work environment with our professional Laminar Flow Hood drawing. This free MechStream download is the definitive blueprint for anyone needing to build or specify a clean bench for a laboratory, electronics assembly, or sterile processing. A laminar flow hood is essential for protecting sensitive samples, cultures, or components from airborne contamination by creating a continuous, unidirectional flow of ultra-clean, HEPA-filtered air.

This drawing package provides a complete, fabrication-ready design, saving you valuable engineering time. It is engineered to solve the most critical aspects of clean bench design: the airflow dynamics. The design details a high-volume fan, a carefully shaped internal plenum to ensure even air pressure, and a large HEPA filter. This combination is the key to achieving a true, non-turbulent “laminar” flow, which sweeps contaminants away from the work surface.

This download includes universally compatible DWG, DXF, and PDF formats, allowing you to easily adapt the design. Whether you’re building a horizontal flow hood (blowing air toward the user) or a vertical flow hood (blowing air down onto the work surface), this template provides the foundational geometry.

Caractéristiques principales :

  • HEPA Filter Integration: The design is built around a standard-size High-Efficiency Particulate Air (HEPA) filter, the core component that removes 99.97% of 0.3-micron particles.
  • Optimized Air Plenum: Includes a specially shaped internal chamber (plenum) designed to receive air from the blower and distribute it evenly across the entire face of the HEPA filter, preventing turbulence.
  • Blower & Pre-filter Mounts: Features a robust mounting system for the main blower/fan and a dedicated slot for a pre-filter, which protects the more expensive HEPA filter from large dust.
  • Fabrication-Ready Body: The drawing includes detailed sheet metal or (stainless steel/polypropylene) construction plans, with callouts for a clear sash and work surface.
  • Vertical & Horizontal Adaptable: The core components (blower, plenum, filter) can be easily re-oriented, making this drawing a perfect foundation for either vertical or horizontal flow configurations.
