Air filters are filtration-based air purifiers. The HEPA filter we often hear about stands for High-efficiency Particulate Air Filter.

 

Let's break down the five core principles of air filtration to help you understand its underlying logic.

 

 

1. Interception Effect: The fibers in a filter are intricately arranged. When airborne dust particles come into contact with the surface of the filter fibers, they are directly trapped if the particle is close enough to the filter material. This phenomenon is particularly evident in dense filter materials, such as the three-dimensional mesh structure formed by ultra-fine fibers in meltblown fabric for masks, which can firmly lock viral aerosols within the fiber gaps.

 

2. Inertial Effect: The complex arrangement of filter fibers in an air filter causes airflow to encounter obstacles and deflect as it passes through the filter material. Dust particles in the air, under the influence of inertial forces, break away from the streamline and collide with the surface of the filter fibers, depositing there. The larger the particle, the greater the inertial force, the greater the likelihood of it being blocked by the filter fibers, and the better the filtration efficiency.

 

3. Diffusion Effect: The diffusion effect targets ultrafine particles smaller than 0.1 micrometers. Particles smaller than 0.1 micrometers primarily undergo Brownian motion, exhibiting a disordered trajectory, significantly increasing the probability of contact with filter fibers; the smaller the particle, the easier it is to remove.

 

4. Gravity Effect: When the airflow velocity is lower than the particle settling velocity, larger particles naturally settle under gravity. Flue gas treatment towers in thermal power plants expand the space and reduce the flow velocity, allowing dust to fall into the dust collection hopper like sand settling to the bottom of water. This mechanism is economical and efficient for treating high concentrations of dust, but its effect on suspended particles is limited, and it is usually used as a pretreatment method.

 

5. Electrostatic Effect: Electrostatic electret technology charges the fibers, giving the filter material the ability to actively capture particles with opposite charges, much like a magnet attracts iron filings. This mechanism is particularly effective for charged particles in PM2.5, and industrial dust removal equipment performs electret treatment on the filter surface.

 What is Cleanroom Engineering? 

 

Simply put, cleanroom engineering is a systematic project that uses air filtration, airflow control, and environmental monitoring to control pollutants such as dust, microorganisms, and harmful gases within specific standards in a cleanroom, while maintaining stable parameters such as temperature, humidity, and pressure differential.

 

From ISO 14644 cleanliness levels (Class 1 to Class 9) to GMP pharmaceutical workshop standards, the requirements for cleanliness levels vary significantly across industries—the electronics industry may require Class 5 (≤352 0.5μm particles per cubic meter), while food workshops typically only require Class 8.

 

 

 Why must factories prioritize cleanroom engineering? 

 

1. Maintaining the Bottom Line of Product Quality

In precision manufacturing fields such as semiconductors and optical instruments, even particles 1/200th the size of a human hair can cause short circuits and decreased precision; in the biopharmaceutical industry, excessive microbial levels directly violate GMP regulations, posing a risk of production stoppage. 1. Cleanroom engineering controls pollution at its source, reducing product defect rates by over 30%.

 

2. Compliance is a prerequisite for production.

Industries such as pharmaceuticals, medical devices, and food contact materials are subject to mandatory national cleanliness standards for production environments. Even with advanced technology, workshops that fail cleanroom engineering acceptance cannot obtain production licenses.

 

3. Reduce hidden production costs.

Uncleaned workshops may increase costs due to frequent rework, batch scrapping, and accelerated equipment wear. A well-designed cleanroom system, while requiring initial investment, can recoup costs in the long run through stable production efficiency.

 

4. Protect occupational health.

In industries such as chemicals and spray painting, untreated volatile organic compounds (VOCs) and dust in workshops can harm employee health. Cleanroom engineering's waste gas treatment and fresh air systems can simultaneously achieve "clean production" and "healthy work."

 

 

 What are the core systems included in cleanroom engineering? 

 

A complete cleanroom system is not a single piece of equipment, but the result of multiple systems working together:

 

Air Purification System: The core components are high-efficiency particulate air (HEPA) filters and ultra-high-efficiency particulate air (ULPA) filters, working in conjunction with pre- and medium-efficiency filters to form a three-stage filtration system capable of intercepting over 99.97% of particles as small as 0.3μm.

 

Envelope Structure: Utilizing dust-proof, mildew-proof, and easy-to-clean materials (such as stainless steel and PVC roll materials), the junctions between walls, floors, and ceilings are rounded to prevent dust accumulation.

 

Ventilation and Differential Pressure Control: Maintaining positive pressure in the clean area by ensuring the supply air volume exceeds the exhaust air volume to prevent external contaminants from entering; a pressure gradient (typically 5-10 Pa) is established between areas of different cleanliness levels.

 

Cleanroom Auxiliary Systems: These include air showers for personnel entry, pass-through windows for material transfer, and clean benches, minimizing the introduction of contaminants through meticulous attention to detail.

In modern industrial and commercial environments, air quality management has become a critical consideration for business operations. Chemical air filters, as a key component of air purification technology, have been used across multiple industries for decades. They effectively remove odors, corrosive gases, and harmful or toxic gases from the air, protecting personnel health and optimizing the production environment.

 

 The Development of Chemical Filtration Technology 

 

Activated carbon, one of the primary materials used in chemical filtration technology, has been used as far back as 3750 BC. Egyptians first used charcoal to smelt ore to create bronze. By 1500 BC, activated carbon's uses had expanded to treating intestinal ailments, absorbing odors, and for papyrus writing. By 400 BC, ancient Indian and Phoenician civilizations had discovered activated carbon's antiseptic properties and used it for water purification.

 

Today, activated carbon is widely used in air filtration technology. For more detailed information on the classification and filtration mechanisms of chemical filters, please refer to "AMC Pollutant Control - Filter Media."

 

In addition to activated carbon, chemical filtration materials also include coconut shell activated carbon, ion exchange resins, and other adsorbent media, providing highly effective purification in diverse environments.

 

 

 Wide Application of Chemical Filters 

 

With the acceleration of industrialization, air pollution, particularly chemical pollution in the industrial sector, has become increasingly prominent. Unlike conventional cleanroom methods for controlling particulate and microbial contamination, the molecular size of chemical pollutants is often too small to be effectively captured by traditional particle filters. Therefore, chemical filtration technology has become essential for air pollution control, with applications across a wide range of industries.

 

 

 Air Molecular Contamination Control (AMC) 

In high-tech industries such as semiconductor, microelectronics, and photovoltaic manufacturing, even the slightest change in air quality can impact product yield. Consequently, these industries place extremely high demands on chemical filters, requiring the removal of acids, alkalinity, volatile organic compounds (VOCs), refractory compounds (RCs), oxidants, dopants, and ozone to ensure a stable production environment.

Cleanroom are designed to meet varying cleanroom cleanliness requirements, such as Class 100, Class 1000, Class 10,000, Class 100,000, Class 300,000, and even higher. This is why FFU have emerged as a valuable solution to these challenges.

 

 FFU can effectively address challenges in cleanroom. The key advantages are as follows: 

 

1. Space Savings – FFU can save space and address the limited maintenance access above cleanroom ceilings.

 

Because high-quality cleanroom require Class 100 or even Class 10 laminar flow hoods to meet process requirements, large supply air plenums are installed above the cleanroom ceilings. These plenums, along with the supply and return air ducts, take up significant space, limiting maintenance access and sometimes even restricting access to fire escapes.

 

When using FFU, the cleanroom ceiling is divided into several modules, each of which serves as an FFU. This allows for adjustments to meet the pressure balance requirements of the supply air plenum above the ceiling, significantly reducing the required plenum height. This also eliminates the need for large supply and return air ducts, saving installation space. FFU are particularly effective when floor height restrictions are imposed during renovation projects. Furthermore, FFUs are available in a variety of sizes and can be customized to the exact size of the cleanroom. As a result, they occupy less floor height within the supply air plenum, or even virtually no space within the cleanroom, further conserving space.

 

 

2. FFU Flexibility – The FFU's independent design allows for immediate adjustments, compensating for the lack of cleanroom flexibility and addressing the inherent limitations of production process adjustments.

 

Cleanroom structures are typically constructed of metallic panels, and their layout cannot be altered after construction. However, due to constant changes in production processes, the existing cleanroom layout can no longer meet new process requirements. This leads to frequent cleanroom modifications for product upgrades, resulting in significant financial and material waste.

 

By increasing or decreasing the number of FFU, the cleanroom layout can be locally adjusted to accommodate process changes. Furthermore, FFU have their own power supply, air vents, and lighting, saving significant investment. This is virtually impossible to achieve with conventional centralized air purification systems.

 

Because FFU are self-powered, they are not restricted by location. Within a large cleanroom, they can be controlled in zones as needed. Furthermore, as semiconductor production processes evolve, the layout inevitably needs to be adjusted accordingly. The flexibility of FFU makes such adjustments easy and eliminates the need for secondary investment.

 

3. Reduced Operational Burden - FFU systems are energy-efficient, eliminating the drawbacks of centralized air supply systems, which often require bulky air conditioning rooms and high operating costs for air conditioning units.

 

If individual cleanroom within a larger cleanroom building require a higher cleanliness level, centralized air supply units with high air volumes and fan pressures are required to overcome resistance in the ductwork and the resistance of the primary, medium, and high-efficiency filters to meet the required cleanliness level. Furthermore, a single air conditioner failure in a centralized air supply system would halt operation in all cleanroom served by that unit.

 

Although the initial investment in FFU is higher than that of ducted ventilation, their outstanding energy-saving and maintenance-free features make FFU more popular.

Food safety is paramount. For a responsible food company, having a standard-compliant cleanroom is like donning a "golden armor" for its products.

 

However, this "armor" isn't a monolithic structure. Instead, it's scientifically divided into different zones based on production processes and hygiene requirements, with layers of protection to precisely filter risks.

 

 

 Core Principle: Why Zoning is Essential? 

 

The core purpose of cleanroom zoning is singular: to control contamination and prevent cross-contamination.

 

Contamination sources mainly come from three aspects: people, machines, materials, methods, and environment. By physically isolating areas with different cleanliness requirements and coordinating different pressure differentials, airflow organization, and personnel purification procedures, a unidirectional contamination control gradient can be formed from low-cleanliness to high-cleanliness areas, ensuring a high level of cleanliness in the core production areas.

 

 Four Core Functional Areas of a Cleanroom 

 

Typically, a standard food cleanroom is divided into the following four main areas from the inside out, with cleanliness requirements decreasing sequentially.

 

1. Core Production Area (Clean Zone)

 

Function: This is the area where products are directly exposed to the environment, including processes such as ingredient preparation, mixing, filling, inner packaging, cooling, final cooling of semi-finished products for perishable foods, and temporary storage after disinfection of inner packaging materials. This is the "heart" area with the highest hygiene requirements.

 

Cleanliness Level: Typically requires Class 10,000 or higher. For certain special foods, some processes even require localized purification down to Class 100.

 

Management Requirements: Personnel must undergo the strictest first and second changing procedures before entering. Materials are introduced through a pass-through window after disinfection. This area maintains positive pressure to prevent backflow of air from lower-level areas.

 

2. Semi-Clean Area (Buffer Zone)

 

Function: This is the "buffer zone" before entering the clean area, a purification preparation area for personnel and materials before entering the core area. It mainly includes: changing rooms, air showers, handwashing and disinfection rooms, material buffer rooms, and equipment cleaning and disinfection rooms.

 

Cleanliness Level: Cleanliness requirements are lower than the core area but higher than general areas, typically Class 100,000 or Class 300,000.

 

Management Requirements: In this area, personnel complete key steps such as changing shoes, putting on cleanroom garments, and washing and disinfecting hands. Materials undergo pre-treatment here, including removing outer packaging and wiping and disinfecting surfaces. This area serves as a crucial "filter."

 

3. General Work Area (Non-Clean Area)

 

Function: Areas where products are not directly exposed or only undergo simple primary processing. Examples include: raw material warehouses, outer packaging areas, finished product warehouses, testing laboratories (partial), equipment maintenance rooms, and office areas.

 

Cleanliness Level: No strict air cleanliness requirements, but good environmental hygiene must still be maintained, complying with basic food factory hygiene standards (e.g., GB 14881).

 

Management Requirements: Personnel do not need to undergo complex changing procedures, but must wear work clothes and maintain personal hygiene. Access control must be installed between this area and the semi-clean area for physical isolation.

 

4. Auxiliary Area

 

Function: Areas that provide power and support to the cleanroom. Although not directly involved in production, they are crucial. Includes: air conditioning room, water treatment system, changing rooms, restrooms, and sanitary ware rooms.

 

Management Requirements: These areas require regular maintenance to ensure stable operation. Restrooms and sanitary ware rooms, in particular, must be strictly managed; their doors must never open directly towards the clean area.

 

 Dynamic Defense Line: Intelligent Design of Personnel and Material Flow 

 

Static zoning alone is insufficient; dynamic personnel and material flow route design is the soul of zoning.

 

Personnel Flow Route: Must follow the unidirectional flow principle of "low clean area → high clean area".

 

Correct Route: General Area → Shoe Change → First Changing Room (Removing Outerwear) → Second Changing Room (Putting on Cleanroom Gown, Handwashing and Disinfecting) → Air Shower → Core Clean Area.

 

Absolutely Prohibited: When returning from a high clean area to a low clean area, the same route must not be used; a dedicated passage must be designed to avoid cross-contamination.

 

Material Flow Route: Raw Materials → Unpacking and Preliminary Processing (General Area) → Through Material Transfer Window (after Disinfection/Wiping) → Buffer Room → Core Clean Area.

 

Finished Products flow out in the opposite direction, but separately from the raw material flow to avoid cross-contamination.

 

The zoned management of cleanrooms in food factories is a comprehensive art that integrates architecture, aerodynamics, microbiology, and food processing. Every wall, every pass-through window, and every air shower represents a solemn commitment to food safety for consumers.

 

Understanding this knowledge not only helps food industry professionals better implement regulations but also gives every consumer greater peace of mind and confidence in the food we consume. Because true deliciousness stems from the utmost respect and protection for detail.

Tip: High image clarity helps you find veins on all skin tones and in different lighting.

 

Infrared wavelength standards

Infrared wavelength is important for seeing veins well. Experts say you should use vein finders with at least 850 nm wavelength. This helps you see a bigger difference between veins and tissue. Devices with the right wavelength show veins clearly, even on dark skin. Using a device that meets this standard helps you find the right vein on the first try. This makes your work faster and safer for patients.

 

Depth and vein size visualization

Depth resolution and visual layering are important for success. If you can see how deep and wide a vein is, you can pick the best spot for a needle. Medical groups support using vein visualization technology because it helps you check patient anatomy. This leads to better choices for IVs and blood draws. Research shows that deeper veins are harder to puncture. Devices that show depth and size help you avoid painful or tricky spots. This makes patients feel better and more comfortable. When you use a device with strong depth and size features, you make better choices and get better results in healthcare.

In the European Union, these devices are also Class 1 and do not need extra certification. Makers still have to follow strict rules and show their products are safe. An outside group checks the device before it is used in clinics.

Note: Always make sure your device has the right certification for your country. This helps keep patients safe and follows the law.

 

Infection control

Stopping infections is very important in all healthcare places. You want to stop germs from spreading between patients. Many new projection vein finders use a no-contact design. This means you do not touch the patient’s skin with the device. This helps keep your work area clean and safe. Some devices have smooth surfaces that are easy to wipe. You can clean them quickly after each use. These things help protect both patients and staff from infection.

• The no-contact design stops direct contact with patients.

• Smooth surfaces make cleaning easy and fast.

You should always follow your clinic’s cleaning rules. Good infection control keeps everyone healthy.
