Modular Clean Room

Biological Containment Door

Bio-airtight Door is a specialized door system designed for biological cleanrooms, laboratories, sterile workshops, and similar environments. BOBEN Bio-airtight Door establishes a robust cleanliness barrier through high-airtight sealing and a 304 stainless steel body. It features automatic sensor-activated opening/closing to prevent finger pinching, low-noise operation, disinfection resistance, and compliance with biological cleanroom pressure differential requirements. Certified by SGS/CE, it eliminates cross-contamination and ensures regulatory compliance.

Features:

High-airtight seal prevents cross-contamination
Automatic sensor-activated opening/closing for pinch-free safety
304 stainless steel construction withstands disinfection and facilitates cleaning
Meets cleanroom differential pressure requirements for compliance
Low-noise operation with sound level ≤55dB
Optional radiation shielding/antimicrobial coating for bio-compatible environments

What is a Biosealed Door?

A Biosealed Door is a specialized door designed to maintain pressure differentials and air cleanliness between interior and exterior spaces. Its core feature is an integrated sealing system. When fully closed, sealing strips are mechanically or pneumatically compressed to form a virtually gap-free barrier between the door leaf and frame, effectively preventing air leakage and cross-contamination.

Why Are They So Important?

In highly sensitive environments such as pharmaceutical manufacturing, microelectronics production, or biological research, even minor airflow leaks can lead to:

Cleanliness Failure: External contaminants entering the cleanroom.
Cross-Contamination: Mixing of production materials or experimental samples.
Biohazard Spreading: Leakage of dangerous pathogens from isolation zones into the external environment.

Biological airlocks serve as the critical defense line for maintaining environmental control and compliance in these facilities.

FAQ

A: Boben has 14 years of professional experience in R&D, production and sales of modular cleanrooms. As a seasoned foreign trade manufacturer, our business covers Southeast Asia, the Middle East, Europe, Africa and other regions. We deeply understand the local industry standards, certification requirements and market needs of different countries, and have served hundreds of B-end customers including electronics, pharmaceuticals, food processing and laboratories overseas.

A: Our modular cleanrooms cover ISO 1 to ISO 9 (equivalent to Class 100 to Class 100,000) cleanroom classes. They are widely applicable to electronics & semiconductor manufacturing, biopharmaceuticals, medical devices, food sterile processing, precision laboratory research and other scenarios. Each set of products is designed according to the unique process requirements of different industries, such as temperature/humidity control, anti-static design, and microbial pollution prevention.

A: Yes, customization is our core advantage! Based on 14 years of technical accumulation, we can tailor solutions according to your actual needs: ① Cleanroom class (ISO 1-9) and space size; ② Core configurations (HEPA filter system, air circulation mode, constant temperature & humidity system, intelligent monitoring); ③ Material selection (stainless steel, color steel plate, aluminum honeycomb panel, etc.); ④ Compliance with local standards (such as FDA, GMP, CE, etc.). We will provide one-stop customized services from scheme design to final delivery.

A: Absolutely! All our products strictly comply with international standards such as ISO 14644 (cleanroom classification) and ISO 14698 (biological contamination control). We have passed multiple international certifications, and the delivered cleanrooms can smoothly pass third-party testing and certification required by target markets (such as FDA for the US, GMP for the EU, and local certification standards in Southeast Asia/Middle East). We will provide complete technical documents and test reports to assist you in customs clearance and market access.

A: The production cycle is 2-4 weeks for standard configurations and 4-6 weeks for customized solutions (faster than the industry average).
