Product Description

Air Shower Pass Box – Stainless Steel Cleanroom Transfer Chamber with HEPA Filter & Interlock System

The Air Shower Pass Box is a specialized cleanroom auxiliary equipment designed for transferring small items between clean areas or between clean and non-clean areas. This stainless steel air shower pass box combines the functions of an air shower and a pass-through chamber, effectively reducing particle contamination during material transfer. When items are placed inside, high-speed HEPA-filtered clean air jets remove surface dust particles, ensuring only clean items enter the controlled environment. The electronic interlock system prevents both doors from opening simultaneously, maintaining pressure differential and cross-contamination control. This air shower pass box is widely used in pharmaceutical manufacturing, biological laboratories, food processing facilities, and electronics production lines where cleanliness is critical.

Product Features

The Air Shower Pass Box offers multiple advantages that enhance cleanroom operations and contamination control.

1. Efficient Dust Removal Performance
Equipped with a HEPA filter achieving 99.99% efficiency at 0.3μm, the air shower pass box generates high-speed clean air jets at 22 m/s through 4 adjustable nozzles. This ensures thorough removal of surface particles from items before they enter the cleanroom, significantly reducing contamination risk.

2. Durable Stainless Steel Construction
The interior chamber is made of high-quality 304 stainless steel with smooth, rounded corners that prevent particle accumulation and facilitate easy cleaning. The exterior can be finished with either stainless steel or electrostatic-sprayed cold-rolled steel, providing corrosion resistance and long-term durability.

3. Safe Electronic Interlock System
The electronic interlock mechanism prevents both doors from being opened simultaneously, maintaining pressure differential and preventing cross-contamination between areas of different cleanliness levels. Door status indicators show when the opposite door is open, ensuring safe and efficient operation.

4. Optional UV Sterilization
An ultraviolet sterilization lamp can be installed for additional disinfection, meeting GMP requirements for pharmaceutical and medical applications. The UV lamp automatically activates when the door is closed, providing thorough surface sterilization of the chamber interior.

5. Easy Installation and Maintenance
The modular design allows for easy installation through cleanroom walls with pre-cut openings. The HEPA filter is accessible for replacement, and the fan unit requires minimal maintenance. The chamber is designed for simple cleaning with standard disinfectants.

Product Applications

The Air Shower Pass Box serves critical contamination control functions across multiple industries.

Pharmaceutical Manufacturing
In pharmaceutical production facilities, the air shower pass box is used to transfer raw materials, packaging components, and tools between different cleanroom grades. It prevents cross-contamination and ensures compliance with GMP standards for sterile product manufacturing.

Biological and Medical Laboratories
Laboratories handling biological samples, cell cultures, or pathogens use this pass box to safely transfer materials while maintaining containment. The HEPA-filtered air shower removes surface contaminants, and the optional UV lamp provides additional microbial control.

Food Processing Industry
Food production facilities requiring clean environments use air shower pass boxes to transfer ingredients, packaging materials, and equipment into processing areas. This helps maintain hygiene standards and extends product shelf life.

Electronics and Semiconductor Manufacturing
In electronics cleanrooms where microscopic particles can damage sensitive components, the air shower pass box ensures that only pre-cleaned items enter the production area, improving yield rates and product quality.
