Static and Dynamic Pass Boxes for Pharmaceutical Cleanrooms

In pharmaceutical cleanrooms, maintaining contamination control during material transfer is critical. That’s where pass boxes play an important role.

🔹 Static Pass Box

Used between the same cleanroom classification areas

No airflow or filtration system

Equipped with interlocking doors to prevent cross contamination

🔹 Dynamic Pass Box

Includes a HEPA filtration system

Used between different cleanroom classes

Provides continuous air circulation for contamination control

Choosing the right pass box helps maintain cleanroom integrity, product safety, and regulatory compliance.

At Brinda Pharma Technologies Pvt. Ltd., we design and manufacture high-quality cleanroom equipment for pharmaceutical facilities.

 In the high-stakes world of pharmaceuticals, biotechnology, and semiconductor manufacturing, the greatest threat is often invisible. A single airborne particle, a stray microorganism, can compromise an entire batch, costing millions and delaying critical advancements. This is why maintaining a sterile, controlled environment isn't just a guideline—it's the foundation of quality and safety.

The challenge arises during material transfer. How do you move samples, tools, or products from one cleanroom area to another without introducing contaminants? The answer is an essential, yet often overlooked, piece of equipment: the Static Pass Box.

And when it comes to manufacturing this critical component in India, one name stands for quality, customization, and reliability: Brinda Pharma.

What is a Static Pass Box and Why is it Essential?

A Static Pass Box (also known as a pass-through hatch) is a sealed cabinet with two doors, one for each adjacent room. It is designed for transferring materials between two cleanrooms of equal cleanliness levels.

Its entire design is built around one critical principle: preventing cross-contamination. This is achieved through a robust interlocking door system, which ensures that both doors cannot be open at the same time.

A technician in the first room opens their side, places the material inside, and closes the door.

The door on the other side, which was locked, is now unlocked.

A technician in the second room can now safely retrieve the material.

This simple, non-negotiable mechanism creates an airlock, effectively isolating both environments and ensuring the integrity of your cleanroom is never compromised.

Features That Set Brinda Pharma's Static Pass Boxes Apart

When you choose a Brinda Pharma Static Pass Box, you are investing in a system designed for durability, compliance, and ease of use.

Robust Construction: We use high-grade Stainless Steel (SS 304 or SS 316L) for a robust, corrosion-resistant body that is built to last.

Seamless Coving: All internal corners are coved, leaving no cracks or crevices. This coved-corner design makes cleaning and sterilization incredibly simple and effective.

Advanced Interlocking System: Our reliable electro-magnetic interlocking mechanism is the heart of the pass box, providing a foolproof safeguard against simultaneous door opening.

Superior Visibility & Sterilization: We provide double-walled flush glass view panels for clear monitoring, along with a pre-installed UV Germicidal Light with an hour meter to ensure complete surface sterilization of transferred materials.

Intuitive Controls: A simple, feather-touch controller allows for an easy door-release mechanism and operation of the UV and white lights.

Static Pass Box, also known as Pass-Through

A pass box’s primary and only work is to pass materials from one side to the other, between controlled environments of different classes, to avoid airborne cross-contamination. Should any particulate matter be present on the surface of the material being transferred, it is swiped away during the operation. The prime feature of a pass box is the interlocking door mechanism – when the door on one side is open, the door on the other remains closed.

Those who work in cleanrooms know it well: avoiding cross-contamination between rooms with incompatible cleanroom classifications is essential to preserve the desired ISO classification and maintain the integrity of products and processes. One way to achieve this is by minimizing material movement.

Non-viable particles and microorganisms can cause contamination in a cleanroom due to the entry and exit of materials within the controlled environments. With this in mind, designing and correctly installing material transfer equipment is necessary.
