When it comes to maintaining cleanliness in critical environments, pass boxes and air showers play an essential role in cleanroom operations. They help prevent contaminants from entering controlled areas, ensuring compliance with ISO and GMP cleanroom standards.
A pass box, also known as a pass-through chamber, allows materials to be transferred between clean and less-clean areas without compromising the environment. There are two main types: static pass boxes and dynamic pass boxes. Static pass boxes are used between rooms of similar cleanliness levels, while dynamic pass boxes include HEPA or ULPA filtration to maintain air purity when materials pass through areas with different cleanliness classifications.
On the other hand, air showers are small, enclosed chambers installed at the entrances of cleanrooms. Before personnel enter the cleanroom, high-velocity air jets blow off dust and contaminants from clothing and surfaces. This process significantly reduces the risk of contamination brought in by workers and materials.
Both pass boxes and air showers are made from durable materials such as stainless steel, ensuring long-term reliability and easy cleaning. Modern systems may include interlocking doors, UV sterilization, and touchscreen controls for added safety and convenience.
As industries like pharmaceuticals, electronics, and food processing continue to demand ultra-clean environments, the use of pass boxes and air showers has become standard practice. They not only protect products but also help companies meet GMP and ISO 14644 regulatory requirements.
Investing in these cleanroom solutions ensures operational efficiency, product safety, and a contamination-free production environment.
