Specification and Data
What is a Cleanroom Pass Through Box?
Are you struggling to maintain strict ISO classifications while constantly moving materials in and out of your controlled environment? Unnecessary foot traffic is the leading cause of particulate contamination. We engineer the cleanroom pass through box to directly eliminate this risk.
A pass through box acts as a secure airlock system mounted seamlessly into your cleanroom wall. Our solutions provide a safe, efficient way to transfer parts and tools between cleanrooms and non-clean environments without compromising the integrity of either space.
By implementing our pass through boxes, your facility immediately benefits from:
- Minimized Traffic: Drastically reduces the number of times personnel must enter and exit the clean space, limiting human-borne contaminants.
- Pressure Stabilization: Maintains critical positive or negative air pressure differentials during material transfers.
- Contamination Control: Acts as a physical barrier to block external particulates from entering your highly controlled environment.
Core Features & Engineering Excellence of Our Pass Through Boxes
When you install a cleanroom pass through box, you need absolute confidence that your controlled environment stays protected. We engineer our pass through boxes to meet strict US manufacturing standards, focusing on durability, particle control, and seamless operation.
Reliable Interlocking Door Systems
The most critical function of any interlocking pass through is preventing cross-contamination. We equip our units with heavy-duty mechanical or electronic interlock mechanisms that guarantee only one door can open at a time. This foolproof system stops untreated outside air from rushing into your clean space while materials are being transferred.
Premium Stainless Steel Construction
We construct every stainless steel pass box from premium 304 or 316-grade stainless steel. This material withstands harsh chemical wipe-downs, resists corrosion, and provides a seamless, ultra-smooth surface. Because it integrates perfectly with your existing ESD cleanroom equipment, daily upkeep is straightforward. When removing minor debris from the interior corners, using an anti-static tool like an ESD brush ensures you protect the surface without generating friction charges.
Airtight Sealing & Flush Design
Particle traps are a major risk for high-grade environments. To solve this, our cleanroom material transfer hatch uses a completely flush-mounted interior design paired with specialized compression gaskets. When the doors shut, the heavy-duty seals create an airtight barrier that actively maintains your facility’s precise pressure cascade and prevents microscopic leaks.
Optional UV Sterilization
For labs and medical facilities acting as a pharmaceutical pass box, biological decontamination is mandatory. We offer optional integrated UV germicidal lighting. These add-on UV lights automatically cycle on during the transfer process to quickly sterilize material surfaces before they ever cross into your sterile zone.

Static vs. Dynamic Pass Through Boxes: Choose Your Configuration
When outfitting your facility, selecting the right clean room pass through box comes down to the specific environments you need to bridge. We build both static and dynamic configurations to handle different levels of contamination risk.
Static Pass Boxes
A static pass box is your go-to solution for moving materials between two cleanrooms that share the exact same cleanliness level.
- Passive Transfer: Relies on heavy-duty interlocking doors and airtight seals rather than active airflow.
- Equal-Grade Environments: Perfect for transferring already-clean supplies—like our low-particulatecleanroom notebooks—between equal ISO zones without dropping room pressure.
- Zero Power Required: Simple, highly durable, and cost-effective.
Dynamic Pass Through Boxes
If you are moving items from a lower-grade environment into a strictly controlled space, you need a dynamic pass through box. These function as self-contained mini air showers for your materials.
- Active Airflow: Engineered with integrated Fan Filter Units (FFU) to continuously cycle and scrub the air inside the chamber.
- Advanced Filtration: As a true HEPA filter pass box, it utilizes HEPA or ULPA filters to strip particulate matter off items before the clean-side door can be opened.
- Cross-Contamination Barrier: The absolute best choice for transferring materials from an unclassified hallway into a highly rated cleanroom.
Configuration Comparison
| Feature | Static Pass Box | Dynamic Pass Through Box |
|---|---|---|
| Best Used For | Cleanrooms of identical cleanliness levels | Lower-grade to higher-grade environments |
| Air System | Passive (Airtight enclosure) | Active Fan Filter Unit (FFU) |
| Particle Filtration | None | Integrated HEPA / ULPA filters |
| Primary Goal | Maintain air pressure during transfers | Actively decontaminate materials before entry |
Industry Applications for Cleanroom Pass Boxes
Our pass through boxes are engineered to meet the rigorous demands of industries where contamination control is critical. Since 2003, we have tailored our cleanroom solutions to support specific operational workflows, ensuring safety and efficiency across various sectors.
- Microelectronics & Semiconductor:
This is our core expertise. In semiconductor manufacturing, even microscopic dust or a minor static discharge can ruin a batch of wafers.

Frequently Asked Questions (FAQ)
How do I clean and maintain the pass-through box?
Regular maintenance keeps your cleanroom pass through box running smoothly and your environment contaminant-free.
- Daily Cleaning: Use standard cleanroom wipes and approved solvents, like 70% isopropyl alcohol, to wipe down the interior. Always wipe from top to bottom, and from back to front.
- Proper Gear: Ensure your maintenance team follows protocol. Wearing appropriate cleanroom apparel, such as a full anti-static labour suit, prevents skin flakes or outside dust from settling inside the chamber during cleaning.
- Monthly Checks: Inspect the airtight sealing gaskets and hinges for any signs of wear. Replace them immediately if they show cracks to maintain strict air pressure.
Electronic vs. Mechanical Interlocks
The main job of an interlocking pass through is to physically prevent both doors from opening at the same time, stopping dirty air from rushing into the cleanroom.
- Mechanical Interlocks: Rely on a physical, internal rod system. When one door is opened, the rod shifts to physically jam the other door shut. They are reliable and don’t require power.
- Electronic Interlocks: Use sensors and heavy-duty magnetic locks. They are smoother, quieter, and generally last much longer because there are no moving metal parts grinding against each other.
Do you offer custom dimensions for existing wall cutouts?
Absolutely. If you are upgrading your facility and already have an existing wall mounted pass through space, we build to fit. Whether you need a basic stainless steel pass box or a highly specialized pharmaceutical pass box, just send us your wall cutout dimensions. We handle the custom engineering to ensure a flush, airtight fit with zero dead space.
How does the dynamic pass box’s air shower function work?
A dynamic pass through box actively cleans materials before they enter your most critical spaces. Here is exactly how the process flows:
- Loading: You place the material inside the chamber and close the door.
- Activation: The built-in Fan Filter Unit (FFU) automatically kicks on.
- Scrubbing: High-velocity clean air blasts over the materials, effectively knocking off loose surface particles.
- Filtration: The dirty air is pulled down through return grilles and pushed through the HEPA filter pass box system, trapping 99.99% of particles.
- Unlocking: Once the timed air shower cycle finishes and the internal air is purified, the opposite door unlocks for safe material transfer.
