pHow It Pass Box Works?
Design
A pass box is often a tiny, enclosed compartment with two entrances on either side. These doors are interlocked, which means that neither can be open at the same time. Electronic locks or mechanical interlocks may be used on the doors to ensure that only one door is open at any given moment.
Installation
Pass boxes are often installed into the walls or barriers that separate the two areas that must be linked. They can be flush-mounted or surface-mounted, depending on the needs of the facility.
Operation
When an operator wants to move materials or objects from one side of the pass box to the other, they open one door on their side of the pass box. This action causes the interlock mechanism to lock the opposing door, preventing both doors from being open at the same time.
Transfer
The operator can then move the items into the pass box and close the door on their side. After closing and locking the door, the interlock mechanism releases the door on the opposite side, allowing someone on the other side to access it and recover the contents. This method guarantees that no direct airflow exists between the two environments throughout the transfer, lowering the danger of contamination.
Categories Of Pass Box
Dynamic Pass Box
A Dynamic Pass Box is an effective material transfer equipment that works on the principals of Laminar Air Flow in conjunction with an interlock system and helps pass material from a non-controlled environment to a controlled environment. This Pass Box comes in single or double-door configuration and gets used depending on the industry applications. In this configuration of the Pass Box, a jet of clean HEPA filtered air penetrates the transfer passageand prevents contamination from entering the other classification area of the clean room.
Static pass box
On the other hand, the Static Pass Box, also known as a Passive Pass Box, helps in material transfer between two cleanrooms of same classification levels without or with little human intervention. It's a simple transfer hatch between two zones and contains an electromagnetic interlock between two doors. However, an LED glare from an optical control point of view indicates when a door is open.

Things To Know About Cleanroom Pass Box
Static, Semi Active And Active Pass Boxes
Pass boxes are available in 3 different types: static, semi active and active. The main difference is the ventilation and contamination filtering.
Easy to clean
Choosing a pass box with flat surfaces is much easier to clean because there is only a flat surface to be wiped, saving time and making it easier to maintain. The material of the cover should also be considered since it should not react with any of the chemicals present in the cleaning products.
Easy to integrate
System independent cleanroom pass boxes fit into any wall systems. KleanLab's range of cleanroom pass boxes work with any structure, including sandwich panels and gypsum boards.
Advanced air tightness
Precise closing is critical when transferring material into the cleanroom. An aluminum profile system can guarantee the perfect air tightness for cleanrooms. KleanLabs pass boxes are equipped with premium EPDM gaskets.
Interlocking
Interlocking is pivotal safety feature of a cleanroom pass box. The system makes sure that only one door is open at a time by using a pin. A led indicator light signals when the door at the other end can be opened. There is also an option for electronic interlock pins for a sluice system with an emergency button for even better safety.
Heavy duty body
When making a serious investment, durability is of key importance. Pass boxes with 50 mm thick, aluminium panels are resistant to bending and ensure long-lasting performance. Finding a material that can withstand the challenges of an industrial environment can be tricky. However AISI 304L stainless steel is completely shockproof and is very un-reactive to other chemicals.
Industry leading design
Anodized aluminium doors are both durable and easy-to-maintain. KleanLabs have created a unique design for their pass boxes which makes cleaning and using them very convenient. They are lightweight and sit flush to the cleanroom walls so that the accumulation of dust is avoided completely. This makes the pass boxes both functional and aesthetically pleasing.
Air pressure drain
Request an air pressure drain to prevent overpressure and constant inflating. This tool will help keep the air pressure under control and maximise safety.
UV light
Germicidal and antibacterial UV light can be installed into pass boxes for enhanced protection. The short-wave ultraviolet radiation destroys DNA pathogens.
Delivery and support
Once a decision has been made about the type of cleanroom pass box required, its time to choose a supplier. Whether its a small or big company, take a look at the services provided. Make sure that all the necessary accessories and parts can be ordered and delivered should there be a problem in the future. This will prevent having to replace the box or the whole pass-through at a significantly higher cost. Also check the estimated turn around times, from order to delivery. When a problem arises in a cleanroom, every minute is critical.
Modern pass boxes are engineered with a variety of features aimed at enhancing both functionality and usability. One of the most crucial aspects is ease of cleaning. Pass boxes are often used in environments where maintaining stringent hygiene standards is essential. Therefore, they are designed with smooth surfaces and minimal seams to facilitate thorough cleaning and disinfection. This design minimizes the risk of contamination, making the pass box a reliable component in controlled environments.
Integration capabilities are another significant feature of modern pass boxes. These units can be seamlessly integrated with existing systems, such as HVAC or laboratory management systems, ensuring that the pass box operates within the broader framework of a facility’s infrastructure. Advanced air tightness is also a key feature, often achieved through high-quality gaskets and precise manufacturing techniques. This ensures that the pass box maintains a controlled environment, preventing any cross-contamination between the cleanroom and the external environment.
Interlocking mechanisms are vital for maintaining the integrity of the controlled environment. These mechanisms ensure that only one door of the pass box can be opened at a time, effectively preventing any potential contamination. Heavy-duty construction is another hallmark of modern pass boxes. Built from robust materials like stainless steel, these units are designed to withstand rigorous use while maintaining their structural integrity and performance over time.
In terms of design, industry-leading pass boxes are often customizable to meet specific user requirements. Optional features enhance their versatility and performance. For instance, air pressure drains can be incorporated to manage differential pressures more effectively, while UV light options provide an additional layer of sterilization, ensuring that the pass box remains free from microbial contamination.
