タイトルまたは説明

The material handling air showers from Weiber brand have been specifically designed to provide a contamination free working area for conducting routine experiments and studies. These energy efficient units are fully self-contained and well equipped to provide and sustain a highly sterile working environment. Our versatile air showers are quite adept at controlling the level of contamination for particle sensitive processes such as disc drive and semiconductor manufacturing, pharmaceutical drug testing and for research applications involving molecular biology and biochemical experiments, cell and tissue culture experiments etc.

Equipped with reset default function, auto reset feature and alarms and indicator lamps for open doors, fluctuations in set parameters and power failure, our air showers offer an unmatched ease of use that makes us the leading brand for laboratory equipments. The side flow air shower is easy to install and is operational with a simple plug-in to the power source. Our fully automatic air showers use microprocessor based controllers for highly accurate working conditions and LED display for ease of monitoring. The automatic reset feature automatically resets the equipment to a safe working level, thereby saving controller settings for smooth operation and preventing system failure and any accidental lock-outs. Weiber air shower design offers unmatched prices, specifications and usages for biotechnology lab and other laboratories.

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 *9.*9% 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 *0% 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.

Construction Details
Our wooden air showers use extremely durable, heavy industrial grade wood and highly resistant and non-corrosive mica or high grade ss***4/ss***6 stainless sheets as construction materials. The internal surfaces of our mobile air showers are plastic laminated and available in attractive finishes. Both the doors feature an attractive aluminium panel and clear view glass/ acrylic panels.
 
The programmable solid state circuit control system located at the junction box of the unit allows programming of the operating conditions. The programmable microprocessor based system detects even the minutest fluctuations from the set parameters to ensure uniform and accurate working conditions throughout the working chamber. The control unit also allows the user to adjust the air nozzles for adjusting the air flow and face velocity to ensure optimum efficiency of the equipment. It also allows setting of the operation time from **9,**0 seconds as per the requirements of specific applications.

High performance motor and blower assembly
The permanently lubricated centrifugal motors and blowers are well balanced statically and dynamically to ensure high performance. They conform to the national product standard and have ISI bearing. *9. The *1 CFR compliant air shower has been designed to produce least disturbance due to vibrations and noise levels, often below *0db and are quite energy efficient.

Filter assembly
Weiber clean room air showers come equipped with efficient and easy to clean pre-filters and HEPA filters for maintaining a contamination free working environment. The HEPA filters are up to *9.*9% efficient in removing particles as small as 0.3 microns and the more efficient ULPA filters capable of removing smaller particles up to 0.1 microns in size are also employed to achieve a higher degree of sterility.

Indicator lamps and emergency switch
The indicator lamps alert the user in case of an unlocked or open door and the emergency switch unlocks both the doors instantly to prevent accidental lockouts.

Illumination system
Our steel air showers use top mounted fluorescent lights, concealed within a light panel, for adequate illumination of the working area. The lighting arrangement conforms to the US federal standards and provides a minimum illumination level of **0 lux.
