Seamless & Contamination-Free Material Transfer

At Kondaas Airtech, our Pass Box Systems (APB) are engineered to be the safest and most efficient solution for transferring materials in and out of cleanroom environments. Mounted directly onto the cleanroom wall, our pass boxes act as a secure buffer zone — ensuring that every item entering or leaving your controlled environment does so without compromising cleanliness or air integrity.

What Is a Pass Box?

A pass box is a wall-mounted transfer chamber designed to facilitate the movement of goods between areas of varying cleanliness levels — all without disrupting the cleanroom’s airflow, pressure, or contamination control. By eliminating the need to open main cleanroom doors during material transfers, pass boxes preserve the integrity of your controlled environment at all times.

How It Works

When materials are transferred, opening cleanroom doors can disturb critical airflow and pressure balances. Kondaas Airtech pass boxes feature an interlocking door control system, ensuring that both doors can never be opened simultaneously. This essential mechanism prevents cross-contamination and maintains a consistently controlled transfer process — every time.

Types of Pass Boxes by Kondaas Airtech

Choosing the right pass box is critical to maintaining cleanroom performance. We offer pass boxes in 5 distinct variants — Advanced, Biohazard, Static, Dynamic, and Shower — each tailored for specific operational needs. All models are available in two primary configurations:

Static Pass Box (Passive Pass Box)

The Static Pass Box is ideal for transferring materials between two rooms of equivalent cleanliness levels where personnel movement is minimal. Designed for reliability and simplicity, it keeps materials fully protected within a controlled environment throughout the transfer process. A trusted, cost-effective solution for shifting non-sensitive products between cleanrooms of equal classification.

Key Highlights:

• Designed for equal cleanliness level transfers
• Minimal personnel movement required
• Reliable contamination barrier
• Excellent performance in cleanroom units

Dynamic Pass Box (Active Pass Box)

The Dynamic Pass Box takes material transfer to the next level. Built for environments where active contamination control is essential, it enables materials to enter controlled environments without any personnel movement. Equipped with a built-in UV light system, the dynamic pass box provides an added layer of sterilization, making it the preferred choice for high-sensitivity and high-risk transfer applications.

Key Highlights:

• Active contamination control during transfer
• No personnel movement required
• Built-in UV light for enhanced sterilization
• Ideal for sensitive and high-risk environments
