The pass box clean room is an essential auxiliary device designed to prevent pollution or cross-contamination when transferring items between a modular clean room and the outside environment. Mainly used for the safe transfer of small objects between a modular clean room, clean room (area), and non-clean room (area), this equipment significantly reduces the frequency of door openings. Consequently, a high-quality cleanroom pass box is highly conducive to maintaining the stable pressure differentials required in controlled environments.
To guarantee that the clean room is not contaminated during item transfer, cleanroom pass thru boxes generally feature a reliable built-in interlock function. This mechanism ensures that when one door is opened, the opposite door remains locked automatically. For seamless observation, the doors on both sides of the cleanroom pass box are equipped with double-layer tempered glass. Each door is also fitted with a heavy-duty handle for easy opening and closing. Furthermore, depending on your specific operational needs, advanced options can be integrated, including buzzers, walkie-talkies, intelligent control touch screens, and differential pressure meters. As a professional pass box manufacturer, Anne Parker also offers optional ultraviolet germicidal lamps (pass box uv light) to fulfill strict sanitization and purification needs.
As an experienced pass box supplier, Anne Parker utilizes premium materials to meet diverse industry standards. According to the production material, our pass box types are divided into full stainless steel pass boxes, heavy-duty baking steel plates, and customized pass boxes featuring a stainless steel interior paired with an outer baking paint finish. All surfaces are meticulously processed to be level, smooth, and easy to clean.
According to the mechanism of the door lock, the lab pass box can be categorized into an electronic interlock pass box and a mechanical interlock pass box laboratory type by global pass box suppliers. The electronic cleanroom interlock pass box is precisely controlled by electronic signals, ensuring absolute safety, while the mechanical interlock utilizes a reliable physical structure. Currently, electronic interlocks are more widely applied in modern labs, though mechanical interlocks remain a dependable choice for specific clean rooms that do not require complex electronic control.
Furthermore, according to the method of air purification, the pass through box clean room can be classified into four primary types: ordinary static pass box, air shower pass box, laminar flow dynamic pass box (also known as a self-cleaning active pass box), VHP pass box, and specialized biosafety pass box for microbiology lab environments.
The ordinary cleanroom static pass box does not feature an active purification function and is ideal for basic transfers.
The pass box air shower type is equipped with high-velocity nozzles that blow away surface dust from items, making it highly suitable for the mechanical and electronic industries, as well as heavy industrial pass box applications.
The laminar flow dynamic pass through box is equipped with a high-efficiency air purification device at the top to provide a steady ISO Level 5 clean environment. It is fully integrated with a PAO dust outlet and a DOP detection port, making it perfect for industries with stringent purification requirements, such as pharmaceutical factories and a pass box in microbiology lab settings.
According to the door operation type, the clean room pass through box can be divided into standard manual doors and automatic pneumatic lifting doors. Manual doors are suitable for standard day-to-day items, whereas pneumatic lifting doors deliver higher efficiency for handling a large volume of goods. As leading pass box manufacturers in China, all of our products can be fully customized according to your precise technical requirements and drawings.
