Horizontal Flow Clean Benches
If you do not use large or bulky equipment on the work surface and want to ensure the lowest level of turbulence, horizontal flow might be best for you.
Risks of contamination from operators may be reduced in horizontal laminar flow hoods because hands are located downstream of the airflow. That means anything you might introduce when working within the hood is immediately pushed out of the enclosure.
Application:
It can be widely used in medicine, bio-pharmaceutical, food, optics, microelectronics, sterile laboratory, lant tissue culture etc.

What does a clean bench do?
The clean bench is recommended for work with non-hazardous materials where clean, particle-free air is necessary to avoid contamination. The clean bench ensures that the work surface is constantly flooded with HEPA-filtered air in a laminar flow. Unlike a biological safety cabinet, the clean bench protects the work on the work surface, but not personnel or the surrounding environment from aerosols created on the work surface. The HEPA air filter can trap 99.999% of particles with a diameter greater than and less than 0.3 micron.
Why Laminar flow?
Clean benches are equipped with either vertical or horizontal laminar flow. Both of these configurations provide a unidirectional velocity along parallel flow lines. Simply, all of the air inside the confines of the bench flows in a single direction without backwash, typically an an area of turbulent airflow created by obstructions, equipment, or movement within the clean bench enclosure. Proper enclosure design helps prevent backwash and ensures that the vertical or horizontal laminar air flow continues to protect work on the surface of the clean bench.
