Liquid through air filters, with their high sealing performance and high filtration efficiency (the filtration efficiency for 0.1-0.3μm particles can reach over 99.9995%), are mainly applied in scenarios with extremely high requirements for air cleanliness, especially suitable for environments where dust, microorganisms, and harmful particles need to be strictly controlled. The following are its typical application scenarios:
1. Cleanroom and precision manufacturing industries
Electronics industry
In the production workshops of semiconductor chips, integrated circuits, and microelectronic components (such as photolithography and packaging processes), the concentration of dust particles in the air (especially those smaller than 0.1μm) must be extremely low; otherwise, it may lead to short circuits in the chips and a decrease in yield. As a terminal filtration device, the liquid tank filter can ensure that the clean room meets Class 1 (ISO Class 1) or higher standards.
Optics and Precision Instrument Manufacturing
In the production environment of optical lenses, laser equipment, and precision sensors, it is necessary to prevent particles from adhering to the product surface and affecting accuracy. Liquid trough filters can effectively remove fine dust in the air and ensure product performance.
2. Biomedical and medical health fields
Pharmaceutical industry
The production workshops (GMP clean areas) of sterile drugs (such as injections and biological preparations), as well as the research and development and production environments of vaccines, must strictly control bacterial, viral, microbial, and particulate contamination. Liquid trough filters can be used as terminal filters to meet GMP requirements for “sterile air” and prevent drugs from being contaminated.
Key areas of the hospital
Operating rooms (especially Class 100 and Class 1,000 clean operating rooms): Prevent wound infections caused by bacteria in the air during surgery.
ICU wards and burn wards: Provide a sterile air environment for patients with weakened immunity to reduce the risk of infection.
Biosafety laboratory (P3/P4 level): Prevents the spread of pathogens through the air and protects the safety of laboratory personnel and the environment.
3. Food and cosmetics industry
High-end food processing
In the production workshops of aseptically filled foods (such as dairy products and fruit juices) and health products, it is necessary to avoid food spoilage caused by microbial and dust contamination. Liquid trough filters can be used in conjunction with clean systems to ensure that the production environment meets food-grade clean standards (such as ISO Level 5).
Cosmetics manufacturing
Sterile production workshops for high-purity skin care products and cosmetics prevent airborne particles and bacteria from affecting product stability or causing skin allergies in users.
4. Aerospace and Precision Laboratories
Aerospace manufacturing
In the assembly workshops for satellite components and precision instruments, tiny dust particles in the air can cause equipment malfunctions. Liquid trough filters can provide ultra-high cleanliness air, ensuring the reliability of precision components.
Scientific research laboratory
Nanomaterial laboratories, optical laboratories, molecular biology laboratories, and others have strict requirements for the cleanliness of their experimental environments. Liquid trough filters can reduce the interference of external particles on the experimental results.
5. Other high-demand scenarios
Data center and chip testing room
Prevent dust from entering precision electronic equipment (such as servers and chip testing instruments), which may affect operational stability.
Nuclear industry-related areas
For some links that have strict requirements for air cleanliness and sealing performance, liquid trough filters are needed to control the diffusion of particles.
In conclusion, the core application scenarios of liquid trough air filters all revolve around “high cleanliness and low leakage risk”, especially playing a key role in industries that require maintaining a stable, clean environment for a long time.
