An air shower, commonly known as a "wind shower" or "cleanroom air shower," is an important component of cleanroom facilities used to minimize contamination transfer into or out of the controlled environment.
A cleanroom air shower is a specialized chamber that is designed to remove particles and contaminants from the surface of an individual or object before they enter a cleanroom environment. It typically consists of one or multiple personnel entry points equipped with high-velocity, filtered air jets.
The primary purpose of a cleanroom air shower is to remove surface particles, loose contaminants, and other airborne particles from the clothing and body of personnel before they enter the cleanroom, thereby reducing the risk of introducing contaminants into the controlled area. The high-velocity air jets dislodge and remove particles through a turbulent flow effect, effectively removing contaminants from the person's clothing, hair, and skin.
Cleanroom air showers are typically equipped with multiple high-efficiency particulate air (HEPA) filters to ensure that the air released is essentially free of particles and contaminants. These filters remove particles as small as 0.3 micrometers with an efficiency of 99.97% or greater.
Furthermore, cleanroom air showers are designed with features that promote efficient and effective particle removal. This includes adjustable air nozzle angles, strategic air outlet placements, and high-velocity air discharges. The air shower duration is set to allow sufficient time for the personnel to be thoroughly cleaned by the air jets, typically ranging from15 to 30 seconds.
Cleanrooms in various industries, such as pharmaceuticals, electronics, and semiconductor manufacturing, rely on the use of air showers to maintain the integrity and cleanliness of the controlled environment. They are essential components for maintaining the desired air quality and minimizing the introduction of contaminants.
In conclusion, a cleanroom air shower is a specialized chamber that utilizes high-velocity, filtered air jets to remove surface particles and loose contaminants from personnel before entering a cleanroom. Its efficient and effective design ensures the cleanliness and integrity of controlled environments in various industries.
