Introduction

In cleanroom environments, material transfer between different cleanliness zones must be strictly controlled to prevent contamination. A cleanroom pass box is an essential device that ensures safe and efficient transfer without compromising air quality.

In this case study, we use a 600×600×600 mm pass box explosion drawing to explain its internal structure, size differences, and how to choose the right configuration for your project.

What is a Cleanroom Pass Box?

A cleanroom pass box (also known as a transfer hatch or transfer window) is a controlled enclosure installed between cleanroom areas or between clean and non-clean zones.

It helps to:

· Reduce particle contamination

· Minimize airflow disturbance

· Limit personnel movement

Typical applications include:

· Pharmaceutical cleanrooms

· Laboratories

· Electronics manufacturing

· Food processing environments

Explosion Drawing of 600×600×600 Pass Box

The 600×600×600 mm pass box is one of the most commonly used standard sizes. The explosion drawing provides a clear view of internal components, helping engineers and buyers understand the design and construction.

Internal Size vs External Size Explained

In this case, it is important to clarify:

· External size: 600 × 600 × 600 mm 

· Internal usable size: smaller than external dimensions (typically around 500 mm range depending on design) 

�� The internal size is NOT equal to the external size.

Why is the internal size smaller?

This is due to structural and functional design, including:

· Stainless steel panel thickness

· Door frame and interlocking system

· Sealing structure

· HEPA filtration system (for dynamic pass box)

�� These components reduce the usable internal space.

Why this matters for buyers

When selecting a pass box, always check:

✔ Internal usable dimensions
✔ Material size to be transferred
✔ Wall opening vs external dimensions

�� Many purchasing issues occur when only external size is considered.

Engineering recommendation

· If items are close to 600 mm, choose a larger model (700 or 800 mm)

· Confirm effective internal dimensions with the supplier

· For dynamic pass boxes, consider airflow system space

Key Components Breakdown

Based on the explosion drawing, a typical pass box includes:

1. Outer Housing

· Made of 304 stainless steel

· Corrosion-resistant and easy to clean

2. Inner Chamber

· Smooth surface with rounded corners

· Prevents particle accumulation

3. Interlocking Door System

· Mechanical or electronic interlock

· Prevents both doors from opening simultaneously

4. HEPA Filtration System (Dynamic Type)

· Efficiency ≥99.99% @ 0.3μm

· Provides clean airflow inside the chamber

5. UV Sterilization (Optional)

· UVC lamp for disinfection

· Timer-controlled operation

Dynamic vs Static Pass Box

�� Static Pass Box

· No fan or filtration system

· Suitable for same cleanliness level areas

· Lower cost

�� Dynamic Pass Box

· Equipped with fan and HEPA filter

· Provides continuous clean airflow

· Suitable for high cleanliness environments

�� Dynamic pass boxes are recommended for pharmaceutical and laboratory applications.

Application Scenarios

This 600×600×600 pass box is widely used in:

· Pharmaceutical cleanrooms (GMP)

· Laboratories (sample transfer)

· Electronics manufacturing

· Food and beverage production

Why Explosion Drawings Matter

Explosion drawings help buyers and engineers:

· Understand internal structure

· Verify materials and workmanship

· Compare different suppliers

· Support project design and installation

�� Especially important for OEM and customized projects.

How to Choose the Right Cleanroom Pass Box

✔ Size

· Standard: 600×600×600 mm
