They are designed to meet all the industrial specifications, making them perfect for use in pharmaceutical industries, microelectronics and semiconductor industries, aerospace industry, high precision manufacturing units and various other industrial applications. We offer air showers in various sizes and packages in both standard and customized designs to meet the industrial specifications. Working principle The air circulating within the air shower tunnel passes through the filter assembly, comprising of pre-filters and HEPA filters, for efficient removal of dust and contaminating particles within the equipment. The clean air is then passed through the nozzles at a high velocity to create pressurized air streams, capable of providing enough scrubbing action for the removal of particulate contaminants adhering to the clothes and skin surfaces of the personnel.The contaminated air is then directed downwards through the grilles and hollow walls of the air shower tunnel and is redirected towards the filter assembly for filtration and recirculation. Filter assembly Our air shower tunnels (tower flow) use top mounted pre-filters and HEPA filters for removing particles as small as 0.3 microns in size and larger with around 99.97% filtration efficiency.The pre-filters are capable of eliminating around 85% of the dust particles, therefore reducing the contaminant load on the HEPA filters and improving its filtration efficiency and life span. The HEPA filters provide a uniform and laminar air flow within the air shower tunnel, therefore ensuring increased air conditioning and energy efficiency while minimizing cross stream contamination. Construction details Our air showers useindustrial grade mica clad heavy wooden boards and high grade stainless steel (SS 304 or SS 316) as construction materials. The internal duct surfaces and all the visible surfaces are covered with plastic laminate to provide a uniform surface and are available in attractive finishes. The magnetically operated and interlocked doors on either side of the air shower tunnel do not open at the same time, therefore restricting the leakage of contaminants from the outside in to the clean room and the biohazardous substances from the clean room to the outside. They are made up of aluminium panel and feature clear view glass/acrylic windows to permit visibility. The compartment access panels are made of coated aluminium and are hinged for ease of handling. They are also equipped with appropriate number of adjustable nozzles mounted on the interior walls and ceilings for maintaining high velocity air streams.
