A cleanroom is a piece of machinery often used within manufacturing that aims to reduce environmental contamination by controlling the environment and riding the space of any contaminants. Cleanrooms are used as part of specialised industrial production and scientific research, such as manufacturing, pharmaceutical products, integrated circuits, and many others. In general, cleanliness is measured by the number of particles per cubic meter and the number of molecules per cubic meter, and it prevents particulates such as dust, airborne organisms, and vaporised particles from entering the environment or keeps them to an extremely low level
The International Standards Organisation imposes the following classifications on cleanrooms: ISO Class 1 (the cleanest) to ISO Class 9 (least clean). A lower ISO rating indicates a cleaner environment. At the same time, the contamination level is rated in parts-per-cubic-meter. Millions of people’s health and safety depend on manufacturers and packagers maintaining a sterile environment during production in industries like pharmaceuticals and food. As a result, clean rooms play an essential role in a range of industries.
There is a direct correlation between cleanroom environments and the consistent production of quality products. Without a suitable cleanroom to drive your system, production will be disrupted or altered. Therefore the quality of the product will degrade. So, here are five things you should know about manufacturing cleanrooms:
Temperature and Humidity
These two factors are integral to the layout and function of a cleanroom. Controlling the temperature is critical to ensure the correct processing of materials and instruments in a cleanroom. Controlling humidity is also essential for preventing corrosion, eliminating condensation on work surfaces, and reducing static electricity. As a result, a balance between these is of particular importance to ensure optimum conditions for your staff and the materials you will store in your cleanroom.
To prevent infiltration by wind, you should maintain your cleanroom at a higher static pressure than the surrounding atmosphere. Additionally, if you are dealing with hazardous materials, ensure that the air pressure is set so that air flows from clean to dirty areas. One exception to the positive differential pressure rule: government agencies require the air pressure to be negative.
It is common to find something as harmless as a person walking across a cleanroom will create turbo-electric charges which accidentally affect and damage certain items. Consider grounding for static protection and replacing the insulating materials where necessary. Cleanroom managers need to carry out a stationary audit to identify potential problems and causes.
Clean rooms aim to attain and maintain airflow. When the flow of air within a confined area moves at a uniform velocity along parallel lines, it is called laminar flow. When airflow is restricted, turbulence occurs, and turbulence can lead to particle movement. The risk of airborne contaminants is reduced when the laminar flow is maintained.
Building ventilation and air volumes are determined by interior air quality, process exhaust replacement, and maintaining building air pressure. Ventilation is the process of exchanging old air with fresh filtered air. Makeup air is the air that replaces the exhaust air that is exhausted from the room during ventilation. Proper ventilation and makeup air in the cleanroom helps better circulation for pure air.
You can guarantee outstanding outputs from your business by having a cleanroom that is designed, engineered and built by a trusted manufacturer like DRYSYS. DRYSYS is your best choice for finding the perfect cleanroom for your business in Australia. In addition to constructing cleanrooms with the most advanced technology available, DRYSYS can provide equipment delivery, design and creation, as well as training your employees to operate, maintain and repair your cleanroom.
