A Static Pass Box is an enclosed transfer chamber installed between two cleanroom areas with similar cleanliness classifications. Its primary function is to enable the safe movement of materials from one controlled area to another while reducing contamination risks associated with personnel traffic.
The chamber features an interlocking door mechanism that prevents both doors from opening simultaneously, helping maintain cleanroom integrity. Many Static Pass Boxes are also equipped with a UV light for surface disinfection of materials before transfer, providing an additional level of contamination control.
Comech Industries manufactures Static Pass Boxes using high-quality stainless steel construction for excellent durability, corrosion resistance, and easy cleaning. Each unit is equipped with a reliable interlocking door mechanism that prevents simultaneous door opening, helping maintain controlled environments during material transfer. The chamber is fitted with transparent viewing windows for easy visibility and can be supplied with an optional UV germicidal lamp for enhanced surface disinfection. Available in various standard and custom sizes, our Static Pass Boxes are designed to meet the operational requirements of different cleanroom applications.
Static Pass Boxes are commonly used in pharmaceutical manufacturing facilities to transfer raw materials, packaging materials, samples, and finished products between controlled production areas. They are also suitable for biotechnology laboratories, hospitals, research centers, medical device manufacturing units, food processing facilities, electronics manufacturing plants, and other industries where maintaining cleanroom integrity is critical. Their simple yet effective design makes them an essential component of contamination-controlled environments.
A Static Pass Box helps reduce contamination by minimizing unnecessary personnel movement between cleanroom areas. The interlocking door system prevents direct air exchange between adjoining rooms, while the optional UV light assists in surface disinfection of transferred materials. The unit improves operational efficiency, supports cleanroom protocols, reduces the risk of cross-contamination, and provides a cost-effective solution for material transfer in controlled environments. Its robust construction and low maintenance requirements ensure long-term reliable performance.
Materials are placed inside the Static Pass Box through one access door while the opposite door remains securely locked. Once the first door is closed, the interlocking mechanism allows the second door to be opened from the receiving side. This prevents both doors from being opened simultaneously, minimizing air exchange between adjacent cleanroom areas. If equipped with a UV lamp, the material can be exposed to ultraviolet light for a predetermined period before being transferred, providing additional surface disinfection before entering the controlled environment.
Comech Industries manufactures reliable cleanroom equipment designed to meet the demanding requirements of contamination-controlled industries. Our Static Pass Boxes are engineered with precision, durable construction, and user-friendly operation to ensure dependable performance and long service life. We offer customized solutions based on chamber size, construction material, door configuration, and installation requirements, allowing customers to select a system that best suits their facility. Our commitment to quality, technical expertise, and customer satisfaction makes us a trusted partner for cleanroom solutions.
What is a Static Pass Box?
A Static Pass Box is a material transfer chamber used to safely transfer materials between cleanroom areas without allowing direct air exchange.
How does a Static Pass Box work?
The system uses an interlocking door mechanism that allows only one door to open at a time, helping maintain cleanroom integrity during material transfer.
What is the difference between a Static Pass Box and a Dynamic Pass Box?
A Static Pass Box does not use HEPA-filtered airflow, while a Dynamic Pass Box includes a blower and HEPA filtration system for active contamination control.
Why is a UV light used in a Static Pass Box?
The optional UV light helps disinfect the surface of materials before they are transferred into the adjoining controlled area.
Where are Static Pass Boxes commonly used?
Static Pass Boxes are widely used in pharmaceutical manufacturing, biotechnology laboratories, hospitals, research facilities, food processing plants, medical device manufacturing, and electronics industries.
