From 2016 to 2017, Qualia successfully applied for national patents on Biosafety Air Tight Door, VHP Generator, Passing Box, Forced Bathing System, Mist Shower, BIBO, Isolator and other products. In 2022, Qualia applied for national invention patents as the first integrated module P3 in China.
Air Shower
Air Shower is a necessary passage for people/goods to enter and exit the clean room, and also serves as an air lock to seal the clean room. In order to reduce the large amount of dust particles caused by the entry and exit of people/goods, the clean airflow filtered by the high-efficiency filter is sprayed from various directions by a rotating nozzle onto the people/goods, effectively and quickly removing dust particles. The cleared dust particles are then filtered by the primary and high-efficiency filters and re circulated to the wind shower area.

Bag in Bag Out
Bag-in-Bag-out is a kind of protective device used for ventilation ducts, the principle of which is to use stainless steel full-welded box as a protective structure, and a filter is installed inside to filter out impurities and particles in the air, so as to improve the safety and quality of the air. In the filtration process, air enters the filter box from the inlet, and after the filter's filtering action, impurities and particles are trapped, while pure air flows out of the outlet. It is widely used in various fields with high risk or high isolation requirements, such as chemical and biological (CB) protection, chemical, biological and radiological (CBR) protection, nuclear, chemical and biological (NBC) protection, etc.

Biosafety Air Tight Door
 
The main function of the Biosafety Air Tight Door is to protect the airtightness of the biological laboratory envelope and prevent external air or pollutants from entering the laboratory, so as to ensure the cleanliness and safety of the internal environment of the laboratory. At the same time, it can also effectively prevent harmful gases or microorganisms from leaking into the external environment in the laboratory, protecting the safety of experimenters and the surrounding environment.

Isolator
Qualia's independently developed Isolator provides high-level protection for products, personnel, and the environment, preventing exposure to potentially infectious aerosols and protecting products from external environmental pollution.Commonly used in biological experiments for biosafety protection, production of allergenic/toxic substances, and breeding of SPF grade experimental animals.

What Is The Life Expectancy of A Biosafety Sealed Valve?

In biosafety facilities, “valve life” is never just about how long a metal body can exist without breaking. A Biosafety Sealed Valve is part of a containment strategy—often installed in HVAC isolation, decontamination pathways, filter housings, or controlled exhaust and supply lines where airtight performance matters. When customers ask us, “What is the life expectancy of a Biosafety Sealed Valve?” they usually mean something more practical: How long will it keep sealing reliably, operating smoothly, and passing verification without becoming a risk or a maintenance headache?

Biosafety Sealed Valve Maintenance Tips To Prevent Seal Wear And Sticking

In high-containment and controlled environments, a Biosafety Sealed Valve is not just another piping component—it is part of the system that helps keep workflows stable, clean, and predictable. When a sealed valve performs smoothly, operators rarely notice it. But when a seal starts wearing prematurely or a valve begins sticking, the impact is immediate: slower operations, inconsistent closing feel, higher risk of leakage pathways, and more frequent maintenance interruptions. These issues are often blamed on “valve quality,” but in real sites we see a different root cause much more often—maintenance habits that don’t match the operating conditions.

What Is A Biosafety Air Tight Door Used For

When most people hear “biosafety,” they think about PPE, biosafety cabinets, or strict operating procedures. But in high-containment spaces, the building itself is part of the safety system—and doors are one of the most important “moving parts” in that boundary. A Biosafety Air Tight Door is not a regular door with a stronger lock. It is a specialized barrier designed to help a facility maintain containment by controlling air leakage, supporting pressure differentials, and reducing the risk of unintended airflow between zones.

How Does A Biosafety Sealed Valve Work How It Maintains Airtight Isolation
2026-03-10

In biosafety facilities, airtight isolation is not a “nice feature”—it is the foundation that supports safe, predictable operation. Whether the system is part of an animal facility, a high-containment lab, a cleanroom interface, or a specialized exhaust and decontamination workflow, the goal is the same: air must move only where it is designed to move, and it must be controllable under normal operation and under abnormal events.
