Horizontal Laminar Flow workstations are designed to protect the product within the work area from airborne particulates in the ambient air. The regulated efflux of custom made laminar airflow supplies the work zone with ISO Class 5 air cleanliness to offer the best product production by a clean bench in the industry. The Horizontal Laminar Flow workstations pushes the air through a HEPA filter and directs the filtered air horizontally over the work surface at a constant speed, toward the operator.
Our versatile unit 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.
Horizontal Laminar Air Flow generally have a taller and therefore a larger loading and working area. This allows for instruments, like microscopes to be placed inside. They are typically the preferred selection for plant tissue culture, media plate preparation, electronics inspection, medical device assembly and pharmacy drug preparation. Because they do not provide protection to the user, they should not be used in conjunction with biohazardous material, toxins or radionuclides. One of the key benefits is the absence of a sash, which is an advantage when placing instruments and equipment inside. This cabinet also known as Laminar Air Flow Cabinet.
Horizontal Laminar air flows can maintain a working area devoid of contaminants. Many medical and research laboratories require sterile working environments in order to carry out specialised work. Horizontal Laminar Flow Cabinets can provide the solution. Why Laminar Flow Cabinets? Horizontal Laminar Flow Cabinets create particle-free working environments by projecting air through a filtration system and exhausting it across a work surface in a laminar or uni-directional air stream. They provide an excellent clean air environment for a number of laboratory requirements.

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/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:
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
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.
