A laminar flow cabinet is a carefully enclosed bench designed to prevent contamination of semiconductor wafers, biological samples, or any particle sensitive materials. Air is drawn through a HEPA/ULPA filter and blown in a very smooth, laminar flow towards the user. The cabinet is usually made of stainless steel with no gaps or joints where spores might collect.
It provides supply of highly purified air in which the total air present in the enclosure moves in a uni directional velocity flowing in parallel lines, which is free from macroscopic fluctuations.
The horizontal laminar air flow units directs the air in mono direction which is away from the specimen and towards the user, giving ultimate protection to the product, which is susceptible to contamination induced by diffusion of contaminated air carrying air transported contaminants from the outside environment.
Construction Details - Our modular units are fabricated of industrial grade stainless steel grade SS-304 or PCRC body as desired. The inner portion painted with epoxy paint coating for extra-long life. The side panels made glass sheets are mounted on anodized aluminum frames.
Noise Level - These laminar air flow units are designed to ensure minimum possible noise and vibration levels.
Illumination - The fluorescent light housing is externally mounted to provide optimum lighting into the work area. The acrylic top and side panels allow for additional ambient light and visibility into the work area.
Filter Assembly
Laminar air flows are fitted with fully washable synthetic pre-filter units and secondary high efficiency air filters made of mini pleated non-woven fabric. The efficiency of filters have a rating of better than 99.99% at DOP (cold) and 99.97% at DOP (Hot). Filter units have the capacity to hold all suspended particles of size greater than 0.3 micron.
Motor and Blower Assembly
laminar air flow units are provided with perfectly balanced (Static as well as dynamic) motor and blower motors bearing ISI mark. The rating of the assembly is 1/5 HP. high efficiency pumps which have life log lubricated bearings ensure a trouble free operation for a long time.
Ultra Violet Light
Optimal wattage ultra violet light is incorporated in the illumination panel of laminar air flow to take care of the sterilization of the existing air present in the enclosure, thus ensuring the high standard of cleanliness
