Laminar Airflow (LAF): Definition, Working Principle & Application

  • 07, 05, 2021

1. What is laminar air flow? 

Laminar airflow, also known as laminar air flow, is a device, designed to prevent the equipment and working environment from particles. 

Laminar airflow cabinets create particle-free working environments by projecting air through a filtration system and exhausting it across a work surface in a laminar air stream. They provide an excellent clean air environment for a number of cleanroom requirements.

2. Laminar airflow applications

Laminar airflow is suitable for a variety of applications, especially where a clean air environment is required for smaller items, like electronic devices.

Laminar airflow can be tailor-made to the specific requirements of the cleanrooms, especially in the medical, pharmaceutical, electronic, and industrial industries.

3. Laminar airflow features

  • Laminar air flow is made of stainless steel, with no gaps or joints where particles might accumulate.
  • Provides HEPA filtered airflow through the work area that protects products and samples from airborne contamination
  • Wind speed will be uniformly distributed

4. What is laminar airflow working principle? 

Laminar flow cabinets work by the use of in-flow laminar air drawn through one or more HEPA filters, designed to create a particle-free working environment and provide product protection. Air is taken through a filtration system and then exhausted across the work surface as part of the laminar flows process.

Commonly, the filtration system comprises a pre-filter and a HEPA filter. The laminar flow cabinet is enclosed on the sides and constant positive air pressure is maintained to prevent the intrusion of contaminated room air.

5. Laminar airflow types 

According to airflow direction, laminar flow cabinets can be produced as two common types: Vertical laminar flow cabinets & horizontal laminar flow cabinets

  • Vertical Laminar Flow Cabinets
  • Horizontal Laminar Flow Cabinets

All ensure a workspace devoid of contaminants and may be customed to the cleanroom requirements.
