A biological safety cabinet (BSC) is a box-type air-purifying negative pressure safety device that prevents the release of hazardous or unknown biological microparticle aerosols during experimental operations. It is widely used in fields such as microbiology, biomedicine, genetic engineering, pharmaceutical and biological agent production, hospitals and clinical laboratories, and is a core piece of equipment for the primary biosafety barrier in laboratories.

Pass box with lifting doors (also known as motorized lifting pass-through windows) are key auxiliary equipment in cleanrooms, laboratories, hospital operating rooms, and other similar facilities. They are primarily used for transferring small items between clean and non-clean areas or between areas of different cleanliness levels. Their core function is to achieve vertical transfer of items via a motorized lifting platform. Combined with technologies such as double-door interlocking, sealing design, and ultraviolet disinfection, they effectively reduce the number of times cleanroom doors are opened, lower the risk of cross-contamination, and ensure environmental cleanliness.

Medical automatic radiation shielding doors are special doors designed specifically for medical facilities. They feature radiation protection, automatic opening and closing, and high airtightness, and are widely used in operating rooms, CT scan rooms, radiology departments, and other areas with strict requirements for radiation protection and cleanliness.

Customized interlocks are personalized interlocking control systems tailored to specific scenarios, equipment characteristics, and safety standards. Through the collaboration of mechanical and electronic systems, they achieve safety constraints on personnel, equipment, and processes, fundamentally addressing the pain points of standardized products' "difficulty in adaptation and inaccuracy." They are the core safety guarantee for high-risk scenarios and complex systems.

In the current era of rapid development in the electronics manufacturing and biopharmaceutical industries, humidity control has become a critical factor determining product quality.

In today's increasingly stringent cosmetics industry regulations and rising consumer awareness of product safety, compliant and efficient GMP cleanrooms have become crucial for production. How do you choose a reliable supplier? Aircolourful, with its years of technological accumulation and practical experience, has become the recommended partner for many cosmetics companies.

Sterile medical devices are directly related to patients' lives and health, and their production environment must strictly comply with the requirements of the Good Manufacturing Practice (GMP) for Medical Devices. The construction of a sterile GMP workshop is a core link in ensuring the safety and effectiveness of products, and it is necessary to control the entire process from design and construction to operation and maintenance to build a closed loop of sterile production.

In today's world of rapid technological advancement, increasingly precise industrial production, and ever-more complex daily life, the concept of interlocking acts like a silent guardian. Though often overlooked, it plays an indispensable and crucial role in numerous fields, building a solid, invisible defense line for safe and orderly operation.

Working principle of the variable air volume (VAV) control system: VAV control adjusts the supply and exhaust air volume of the system by changing the opening degree of the fume hood windows in the laboratory, thereby ensuring that the fume hood surface velocity can always be precisely controlled at 0.3-0.5 m/s regardless of the window opening degree.

In the fields of industrial automation, environmental control, and medical equipment, differential pressure gauges are precision instruments that measure the pressure difference between two points and are the "pressure sentinels" that ensure the stable operation of the system. Its core value is not only derived from precise principle design, but also reflected in the detailed application of multiple scenarios. This article will focus on dismantling the essence of the working principle of the differential pressure gauge and explaining its application details in key areas.

A clean booth is a modular, compact cleanroom system designed to create localized Class 100 (ISO 5) to Class 100,000 (ISO 8) clean environments. It isolates work areas from dust (≥0.5μm particles), aerosols, and microbial contaminants, ensuring product integrity in precision-focused scenarios.
