A laminar air flow system is a vital concept in the control of particulate contamination in a pharmaceutical Industry. It provides an aseptic environment in particular area to perform different activities during manufacturing. Cleanrooms in pharmaceutical industry maintain particulate-free air through the use of either HEPA or ULPA filters employing laminar or turbulent air flow principles.
Laminar airflow is working through air moving at the same speed and in the same direction, with no or minimal cross-over of air streams. Most contamination-sensitive environments in a pharmaceutical industry such as dust-free hoods require laminar flow because it predictably sweeps particles in a uniform direction, from the cleanest area under the hood. This design ensures that the cleanest area will always be the upstream area closest to hood. Laminar air flow systems are typically employed across 80% of a cleanroom ceiling to maintain constant air processing.
Laminar Flow Cabinets (tissue culture hood) 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. The Laminar Flow Cabinet is maintained a constant positive air pressure to prevent the intrusion of contaminated room air.
Laminar Flow Cabinets is ideal for general lab work, especially in the medical, pharmaceutical, electronic and industrial sectors. In a pharmaceutical industry, Laminar Flow Cabinets are suitable for a variety of applications and especially where an individual clean air environment is required for particle sensitive products. Owing to its quality in adherence to the international quality standards, this cabinet is also widely used in various clean rooms & micro biological laboratories.
In order to make it highly valuable for keeping safely various air point in clean room application, some manufacturer emphasize on its customized design.
