Laminar Air Flow
Laminar Air Flow (LAF) is a technique used in clean environments like modular operation theatres, pharmaceutical labs, and cleanrooms to control airborne contamination by directing air in a uniform, unidirectional stream.
It’s a key component in maintaining sterility and preventing the spread of airborne particles—especially critical in environments where even microscopic contamination can cause serious harm (e.g., during surgeries or drug production).
Types of Laminar Air Flow:
- Vertical LAF – Air flows vertically from ceiling to floor. Operating Theatres, Cleanrooms
- Horizontal LAF – Air flows horizontally from rear wall toward front. Laminar Flow Cabinets, Labs
Key Components of a Laminar Air Flow System:
- Pre-Filters
- HEPA Filters (High Efficiency Particulate Air)
- Fan or Blower Unit
- Plenum Chamber
- Speed Controller
