Cleanroom Equipment - Realizing The Characteristics Of Various Equipment
Cleanrooms, as the name implies, are areas where you may work without interference from even the most minute dust particles. These areas are highly vital to both manufacturers and scientists alike. Some of the most usual examples where the provision is vital are found in semiconductor and aerospace equipment companies.
Cleanrooms are classified by the ISO from a scale of 1 – the cleanest – to a scale of 9 – the lowest. In ordinary parlance, the number 9 refers to normal room air. All of these rooms are made clean in a variety of ways. Added technologies include air showers, air locks and HEPA filters. Learn about these three technologies in this page.
Air showers
Air showers play an vital role in getting rid of dirt from the suit of workers who go through the cleanroom. This is somewhat similar to the normal bath shower in residences. The difference is it does not make use of blowing water to the body. Pressurized air with a velocity of 300 fpm replaces for the water that is coming out of the shower.
The air shower puts off a blast of air to the personnel. This is to ensure that he is freed from dust and dirt particles. These particles may either be obtained while the employee is changing his suit in a non-sterile place. Most often than not, the floor of the air shower is sticky in order to get particles that were not taken in previous floors.
Air locks
After going through the air shower, the employee gets into another technological procedure in cleanrooms – known as air locks. The need for the airlock relies upon the ISO classification. Obviously, these ones are obligatory for higher scales in the ISO categories. Airlocks are actually used as a form of added protection to get rid of dust and dirt particles absorbed by a worker's body or suit.
Hepa filter technology
High efficiency particulate air or HEPA filters are utilized in order to keep the room clean. These are also significant in cleaning air shower and air lock equipment. These filters contain fiber that is in charge of the catching of particles in a number of ways.
The first technology under HEPA filters for cleanrooms is termed as interception. This is a technology where particles are intercepted by the fibers. The next method is known as impaction or a process where the particles follow the air flow at first before they are crashed into smaller fibers. The last process is known as diffusion or the process in which the particles may be prevented from moving forward but are forced to remain in the airstream of the filters.
