What is a Static Pass Box? Understanding the Basics
A Static Pass Box (also known as a passive pass box) is a simple yet highly effective chamber installed in cleanroom walls. Unlike its dynamic counterpart, it does not have its own filtered air supply. Instead, it relies on the existing cleanroom air and a "barrier" system to move non-sensitive items—such as laboratory glassware, paperwork, or packaged raw materials—between rooms of the same cleanliness level.
As a dedicated Static Pass Box Manufacturer in India, we focus on two core pillars: Durability and Contamination Control. Every unit we produce acts as an airlock, preventing the direct flow of air between rooms, which is vital for maintaining the "pressure cascade" in a facility.
Difference between Static and Dynamic Pass Box
One of the most frequent questions we receive is regarding the difference between Static and Dynamic Pass Box configurations. Choosing the right one is critical for both compliance and your budget.
| Feature | Static Pass Box | Dynamic Pass Box |
| Airflow | No internal airflow (Passive) | Self-cleaning with HEPA-filtered air |
| Transfer Type | Between rooms of similar cleanliness | Between rooms of different cleanliness |
| Application | Moving non-sensitive items | Moving sensitive/sterile items |
| Cost | More affordable price point | Higher investment due to HEPA/Blower |
The Static Pass Box is primarily used for transfers between two "clean" areas where the risk of airborne contamination is equal. If you are moving items from an unclassified area to a Grade B cleanroom, a Dynamic unit is required. However, for most intra-facility transfers, the Cleanroom Pass Box in its static form is the most efficient choice.
Premium Construction: SS 304 Pass Box vs. SS 316
The material of construction (MOC) is the most significant factor in the longevity of a Cleanroom Pass Box. At Rayshen, we offer two primary options:
SS 304 Pass Box (Standard Industrial Grade)
The SS 304 Pass Box is the standard for most cleanroom applications. It is highly resistant to moisture, easy to clean, and provides a sleek, professional finish. It is ideal for electronics, food processing, and general pharmaceutical zones.
Pharmaceutical Static Pass Box SS 316 (Superior Grade)
For environments involving harsh chemicals, high-salinity air, or aggressive disinfection protocols (like VHP), we recommend the Pharmaceutical Static Pass Box SS 316. SS 316 contains molybdenum, which provides superior resistance to pitting and corrosion, making it a "must-have" for API manufacturing and high-end biotech labs.
Key Features of Rayshen Static Pass Boxes
As a premier Static Pass Box Manufacturer in India, we integrate advanced features into every unit to ensure maximum safety and user convenience.
Electromagnetic Interlock Static Pass Box
Safety is paramount. Our Electromagnetic Interlock Static Pass Box ensures that both doors cannot be opened simultaneously. When one door is opened, the electronic sensor automatically locks the opposite door. This "Airlock Effect" prevents the cleanroom from being exposed to outside air, maintaining the sterile environment at all times.
UV Germicidal Integration
To further mitigate risk, every Cleanroom Pass Box can be equipped with a high-intensity UV-C germicidal lamp. This lamp decontaminates the surface of the items sitting inside the box before the second door is opened, providing an extra layer of protection against microbial transfer.
Seamless Internal Design
The interior of our boxes features a "Coved Corner" design. By eliminating 90-degree sharp corners, we prevent the accumulation of dust and bacteria. The base of the box is flush with the wall or floor, ensuring that cleaning is effortless and thorough.

Installation and Maintenance Guidelines
To ensure your Cleanroom Pass Box performs optimally for years, proper installation is key.
Wall Integration
The box should be installed "Flush" with the cleanroom wall using silicone sealant to ensure no air leakage occurs between the wall and the box frame. This is critical for maintaining the pressure differential of the room.
Routine Cleaning
The SS 304 Pass Box should be cleaned daily with a non-abrasive disinfectant. The UV lamp should be checked every 6 months to ensure the germicidal intensity remains effective.
Interlock Testing
A monthly check of the Electromagnetic Interlock is recommended. If the red/green indicators are not functioning, it could signal a sensor misalignment that needs immediate attention to prevent accidental cross-contamination.

Frequently Asked Questions
A Static Pass Box is a controlled material transfer hatch installed between two cleanrooms of the same cleanliness class. It acts as an airlock; the Electromagnetic Interlock Static Pass Box technology ensures that both doors cannot be opened at once, preventing direct airflow between rooms and maintaining the facility's pressure differential.
The primary difference between Static and Dynamic Pass Box is the airflow system. A Static Pass Box is "passive" with no internal filtration, used for transfers between rooms of equal cleanliness. A Dynamic Pass Box is "active," featuring an internal motor and HEPA filter to "bathe" the material in clean air, making it suitable for transfers between non-classified and sterile areas.
The SS 304 Pass Box is the industry standard because Stainless Steel 304 is non-porous, non-shedding, and highly resistant to moisture. As a leading Pass Box Manufacturer, we use SS 304 to ensure the unit can be easily disinfected without rusting, which is critical for maintaining ISO cleanroom standards.
You should opt for a Pharmaceutical Static Pass Box SS 316 if your facility uses aggressive cleaning chemicals like chlorine-based disinfectants or if you are in an API (Active Pharmaceutical Ingredient) plant. SS 316 offers superior resistance to pitting and chemical corrosion compared to SS 304.
An Electromagnetic Interlock Static Pass Box uses electronic sensors to create a fail-safe environment. When a technician opens the door on the "dirty" side, the "clean" side door locks instantly. This prevents accidental cross-contamination and ensures that your cleanroom’s air pressure remains stable at all times.
The Static Pass Box for Cleanroom price depends on several factors: the material of construction (SS 304 vs SS 316), the size of the chamber, and additional features like UV-C germicidal lamps, hour meters, or specialized floor-mounted designs for trolleys.
Yes. As a specialized Static Pass Box Manufacturer in India, Rayshen provides bespoke dimensions. While standard sizes like $450 \times 450 \times 450 \text{mm}$ are common, we can manufacture custom units to fit specific wall thicknesses or to accommodate large equipment transfers.
Yes, every Cleanroom Pass Box can be integrated with a UV-C germicidal lamp. These lamps provide surface decontamination for the items placed inside. We also include a safety interlocking feature that turns the UV light off automatically when a door is opened to protect personnel.
As a Static Pass Box Manufacturer in India, we design our units with peripheral flanges. The box is inserted into the wall cutout, and the flanges are sealed against the sandwich panel using medical-grade silicone, ensuring a flush, "leak-proof" finish that meets GMP guidelines.
Maintenance is simple but essential. Daily cleaning with a non-corrosive disinfectant is required. For an Electromagnetic Interlock Static Pass Box, you should check the door sensors monthly and replace the UV-C lamp every 8,000 to 9,000 hours to ensure maximum germicidal efficiency.
