Material handling air shower tower flow

Key Attributes.

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%. The pre-filters can effectively remove around 85% of the particulate matters, therefore reducing the contaminant load on the HEPA filters and increasing their efficiency and life span. The filtered air is released through adjustable nozzles, arranged in a uniform pattern on the walls and ceilings. The pre-filter unit is fully washable and is made up of non-woven synthetic polyester, whereas the easy to clean HEPA filters are made up of glass pleated non-woven fabric filter. Control Unit The unit is controlled through a programmable solid state circuit control system, located at the junction box of the unit. The junction box is a tamper proof enclosure that houses emergency setting buttons for switching off of the equipment in response to audio visual alarms. The control unit houses the operation timer and nozzle adjustment buttons. Our air showers use microprocessor based controllers for various set parameters and for the detection of any errors or deviations from the set parameters. Construction Details Our air showers use heavy industrial grade mica clad wooden boards and stainless steel (SS-304, SS-316) as construction materials. The internal surfaces are laminated and available in attractive finishes. The unit is provided with interlocked and magnetically operated doors on either side of the air shower cubicle. The doors are made of aluminium panels and have clear view glass/acrylic windows for increased visibility. The compartment access panels are made of aluminium panel and are hinged for ease of operation. Air shower room is a closed cubicle with adjustable nozzles air showers designed for clean room applications. Motor And Blower Assembly The motor and blower motors are statically and dynamically balanced and have permanently lubricated bearings for long lasting and trouble free operation. They bear ISI marking and are rated at 1/5 HP. The blower access panel is located at the side of the air shower unit. Illumination Our air showers use top mounted fluorescent lights for adequate illumination of the shower cubicle. The fluorescent lights panel is concealed at the upper portion of the unit and provides a minimum illumination of 800 lux. The lighting arrangement conforms to the US Federal standards.
