Laminar Air Flow
FEATURES & BENEFITS
- Blower assembly draws room air through pre filter and throws towards HEPA filter
- It is primary air filter which filters room air initially and forward towards HEPA filter
- Air filtered through pre filter is forwarded towards HEPA filter
- Magnehelic gauge is used to monitor differential pressure across HEP filter with respect to ambien
- It is made of stainless steel. Samples / products are put on it for work
- Light is fitted to provide proper illumination under the working area

A laminar air flow workstation is a closed cabinet fitted with HEPA filtered air flow system. Here, laminar means unidirectional constant flow of air with almost no or minimal turbulence. The air flow velocity remains between 0.3 m/s to 0.5 m/s. The purpose of using such workstations in laboratory is to create particle and bacteria free working environment to carry out specialized work. As these units discharge air towards user, they provide no personal protection but product protection from room contaminants. LAF is short form of laminar air flow.
There are two different types of laminar air flow cabinets are constructed; horizontal and vertical. The difference between vertical and horizontal laminar flow hoods is direction of air flow and placement of HEPA filter. These cabinets are made with either horizontal or vertical air flow systems and have two stages filtration. It is the type of application which decides which is most suitable to use.
