Working principle of Material Handling Air Shower (Two side flow) The material handling air showers from Weiber feature a highly efficient pre-filter assembly and HEPA filters with around 99.99% efficiency in removing particles as small as 0.3 microns in size. The air entering the enclosed chamber of an air shower passes through the top mounted pre-filter assembly comprising of fully washable, easy to clean poly fiber synthetic media of around 1’’ thickness and is then directed towards the HEPA filters made up of glass pleated filter media to eliminate dust particles and other particulate matters 0.3 microns in size or larger. The filtered air is then sprayed onto the personnel through top and side mounted jets and nozzles at appropriate face velocities to remove the dust and particulate matters from the skin surfaces and clothes of the person, prior to entering the clean room. The two-way operation of our laboratory air showers allows the air showers to be activated in both the directions to prevent the release of hazardous substances from the controlled environment to the outside, while maintaining clean room conditions within the working chamber. Our two-way material handling industrial air showers are particularly useful in animal research laboratories and pharmaceutical industries for containment of harmful microbes and other hazardous substances. Since only one door can be opened at a time, the release of contaminating particles from the air shower cubicle is effectively controlled in both directions. Efficiency of Material Handling Air Showers (Two side flow) Though there has been some debate over the efficacy of air showers in maintaining clean room conditions in the past decades, the recent test data conclusively proves the efficiency and effectiveness of air showers in maintaining contamination-free working conditions. As indicated by the test results of a series of repetitive tests conducted by a Japanese company several years ago, the air showers can effectively remove up to 90% of the contaminating particles, drastically reducing the contamination levels for a controlled atmosphere. Size The material handling air showers from Weiber are available in both standard and customized sizes to suit individual customer requirements. The standard models offer an internal working space of 1.5mx1.5mx2m /2mx2mx2m/2.5mx2.5mx2m. Weiber is also a leading developer of customized air shower.

Our material handling air showers (tower flow) are enclosed chambers ideally installed in front of a clean room to prevent the entry of contaminating particles within the working area. The Clean room air showers are specifically designed for the elimination of surface particles from the materials, clothes and skin surfaces of the personnel, prior to entering a clean room or controlled environment chamber. Our material handling air showers find widespread use in semiconductor manufacturing units, animal research facilities, pharmaceutical production units, micro fabrication industry and in basic and applied research laboratories. Working Principle of Material Handling Air Showers (Tower Flow) Both the doors of our material handling Tower flow air showers are interlocked and magnetically operated. They are permanently energized and open instantly when the open door push button is pressed. Once the user enters the air shower cubicle, he/she can start the shower cycle from the inside. The shower cycle is programmable and can be set as per the requirements of the industry. Both the doors of the unit remain locked till the shower cycle continues, to prevent the entry of external contaminants while the air shower is operational. Once the Tower flow air shower cycle is completed, the personnel can exit through the exit door. The one-way mode of operation allows the user to enter the air shower cubicle, but he/she cannot exit through the entrance door, therefore controlling the traffic patterns into and out of the controlled environment chamber. Moreover, the pre-purge function of our modular air showers allows the unit to self-clean in a power-on mode. The pre-purge time is also programmable and can be set between 0-3 minutes. Air shower principle is based on subjecting the personnel through adequate velocity of clean air coming through a pre filter assembly. The air present in the air shower cubicle is continuously circulated through the filter assembly, comprising of pre-filters and HEPA filters. The filter assembly physically entraps the contaminating particles and removes them from the air circulation. The efficient fans and blowers blow the filtered air into the air shower cubicle through adjustable nozzles at appropriate face velocities. The turbulent air streams produce enough shearing effect to loosen the dust particles and other particulate matters from the external surfaces, causing their wash down with the air stream. The air shower cubicle is maintained at a slightly higher pressure as compared to the outside to prevent the contaminating particles from entering the cubicle when the unit is at rest. Air Shower specifications are in accordance with the US Federal Standards. Product Description Filter assembly Our quality control air showers are equipped with top mounted pre-filters and HEPA filters for the removal of particulate matters as small as 0.3 microns in size with a filtration efficiency of more than 99.97%.
