Vertical Laminar Air Flow

Vertical Laminar Air Flow

ACMAS Technologies Pvt. Ltd. are leading manufacturer supplier and exporter of Vertical Laminar Air Flow products. We have successfully catered the needs of over 600 institutions in India and more than 42 countries, we serve more than 1500 customers in corporate and private sectors

WEIBER vertical laminar air flows are conceptualized to provide a work area completely bathed in high efficiency perfect air, which is free from any kind of particulate contamination or impurities. These units are ideally suited in all the applications, requiring protection of biological specimens or products from the possible contamination during the process or test. Our laminar air flow bench is fast gaining popularity in other fields, such as pharmaceutical production, electronic industries and various other manufacturing applications.

A vertical clean bench pushes air through a HEPA filter which is located at the top of enclosure. The air is directed downward onto the work surface at a constant speed. It is useful for various works that require maintenance of the cleanness and purity like plant tissue culture, examination and experimentation of precision electronic parts, medical science, entomology, pharmacy, agriculture sector, seed science, veterinary science.

A vertical clean bench, on the other hand, offers a pivoting glass sash as a safety measure. This sash offers personal protection and a physical barrier when working with chemicals. Vertical clean benches are common place in microbiology, forensic, biotech and many other industries, which utilizes them during procedures that require clean work area.

Operating Principle:

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/ULPAfilter 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 unidirectional 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 prefilter 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.
