What are types of Compressed air filters?

In the modern industrial field, Compressed air indispensable as blood, and its internal cleanliness is directly related to whether the production process is smooth and the quality is good or bad. Therefore, accurately selecting the appropriate filter has become a key link to ensure the stable operation of the compressed air system. 1. Clarify the application scenarios of the compressed air system The first step is to deeply understand the application background of the compressed air system. Different industries and processes have different quality standards for compressed air. For example, in high-precision fields such as precision manufacturing, electronic packaging or medical equipment manufacturing, the purity of compressed air is almost harsh, and top-level performance filters are required to ensure that every breath of air is pure and flawless. On the contrary, in some basic industrial fields, only basic-level filtration may be required to meet production needs and maximize cost-effectiveness. The following is Shenzhen Hongrijia's recommended solution for compressed air purification systems in some industries.   2. Quantify the demand for filtration accuracy Filtration accuracy, as a core indicator for measuring filter performance, is directly related to the cleanliness of compressed air. Accurately defining the required filtration accuracy is an important part of the filter selection process. It is not wise to set the accuracy too high or too low. Although too high accuracy can bring the ultimate cleaning effect, it will increase unnecessary costs; while too low accuracy may not meet production needs and affect product quality. Therefore, it is necessary to scientifically set a reasonable filtration accuracy threshold according to the actual application scenario. Hongrijia YUKA high-precision filters mainly have 7 filtration accuracy levels, namely PF/AO/AA/AX/ACS/AR/AAR. Different filtration levels have different filtration accuracy.   3. Detailed study of the characteristics of various filters The type of filter should also be selected according to actual needs. Different types of filters have different functions. Coagulation filter: A filter that allows airflow to pass through the gap of the filter material, and with the help of various filtration mechanisms (collision, diffusion, interception), the water vapor or solid particle suspension in the compressed air is continuously condensed into larger droplets and separated. Activated carbon filter: With its powerful adsorption capacity, it effectively removes organic matter, odor and harmful gases in the air, which is to improve the quality of compressed air. High-efficiency particulate filter: using advanced filter materials, it can efficiently intercept tiny particles and microorganisms, providing solid protection for scenes with extremely high requirements for air quality. Pre-coarse filter: as the first line of defense for air purification, it mainly intercepts large particles and impurities, protects subsequent filter units from damage, and extends the overall service life. In summary, choosing the right filter is the key to ensuring efficient and stable operation of the compressed air system. Hongrijia YUKA has been deeply engaged in compressed air purification systems for more than 20 years. Its products meet the international standards of ISO8573.1-2010, with a filtration efficiency of up to 99.999%, a particle filtration accuracy of ≤0.01 microns, and a residual oil content of no more than 0.003PPM; We have been customer-oriented for many years, and have customized the best compressed air solutions for customers by clarifying customer application scenarios, quantifying filtration accuracy requirements, carefully studying filter characteristics, and comprehensively considering maintenance costs and benefits.      

Function of a Compressed Air Filter

A compressed air filter is designed to remove contaminants from compressed air systems, ensuring clean, dry, and safe air for various applications. Here's a breakdown of its key functions:   1.Removes Moisture: - Compressed air often contains water vapor that condenses as liquid droplets during compression. Filters, especially coalescing types, capture these droplets, preventing corrosion, equipment damage, and process interference (e.g., in painting or pneumatic tools).   2. Eliminates Particulates: - Filters trap solid contaminants like dust, dirt, rust, and pipeline debris. This protects machinery from abrasion, clogs, and premature wear, particularly in sensitive equipment like valves and cylinders.   3. Separates Oil and Aerosols: - In oil-lubricated compressors, oil can enter the air as mist or vapor. Coalescing filters merge oil droplets for removal, while activated carbon filters adsorb oil vapors, critical for applications requiring oil-free air (e.g., food processing, pharmaceuticals).   4. Enhances System Efficiency: - Clean air reduces maintenance costs, extends equipment lifespan, and minimizes downtime caused by contamination-related failures.   5. Ensures Compliance and Safety: - Meets industry standards (e.g., ISO 8573) for air purity, crucial in regulated sectors like healthcare or electronics manufacturing. Also prevents contamination of end products and reduces workplace hazards.   Types of Filters: - Particulate Filters: Capture solid particles. - Coalescing Filters: Remove moisture and oil aerosols. - Adsorption Filters (e.g., activated carbon): Eliminate oil vapors and odors.   By purifying compressed air, these filters safeguard equipment, improve product quality, and ensure operational reliability across industries.

How to purify compressed air?

Purifying compressed air is essential for many industrial applications, as it helps remove contaminants such as water vapor, oil, dust, and other particles that can affect the performance and longevity of equipment. Here's a step-by-step guide on how to purify compressed air:   Sources of compressed air pollutants:   1. Atmosphere Air compressors suck in and compress a large amount of atmosphere. They continue to fill the system while bringing in extremely small pollutants. These pollutants include: water vapor, atmospheric dirt, dust and pollen particles, oil vapor, and microorganisms. 2. Air compressor In addition to the pollutants inhaled from the atmosphere, the air compressor will also mix a small amount of oil into the compressed air flow during the air compression process. This oil may exist in the form of liquid oil, aerosols and oil vapor. It is also worth noting that although so-called oil-free compressors do not directly inject oil into the airflow, they still compress the same contaminated air like an air compressor, so any oil vapor in the surrounding environment will still be affected. It is compressed and enters the downstream system. After the compression stage, the aftercooler cools the air, which can condense any water vapor and mix it into the compressed air stream in the form of liquid water or aerosol.   Primary Filtration Coalescing Filters: These filters remove oil and water droplets by forcing the air through a fine mesh. They are typically installed after the air compressor. Particulate Filters: These remove solid particles from the air, often used before the coalescing filter.   Air Dryers Refrigerated Air Dryers:These reduce the temperature of the compressed air, causing water vapor to condense and be removed. Desiccant Air Dryers: Use a desiccant material (like silica gel) to absorb moisture. They are more effective but also more expensive.   Secondary Filtration Sub-micron Filters: These remove even smaller particles and droplets that might have passed through the primary filters. They are often used near the point of use to ensure extremely clean air.   Drainage - Install automatic drain valves at low points in the system to remove accumulated water and contaminants.   Regular Maintenance - Clean or replace filters regularly to maintain efficiency. - Check and service air dryers as recommended by the manufacturer. - Regularly inspect the entire system for leaks and other issues.   Point-of-Use Filtration - Install additional filters close to where the air will be used if higher purity levels are required.   Tips: Pressure Dew Point: Ensure that the dew point of the air is appropriate for your application. This is the temperature at which water starts to condense out of the air. Flow Rate:Make sure your filters and dryers are rated for the flow rate of your system. Contamination Levels: Know the contamination levels required for your specific application and select filters and dryers accordingly.   By following these steps, you can effectively purify compressed air for various industrial uses, ensuring optimal performance and longevity of your equipment.  

Can I use compressed air to clean an air filter?

Using compressed air to clean a paper or gauze air filter is generally not recommended for several reasons:   1. Damage to Filter Pores: The high pressure from compressed air can enlarge the pores in the filter material, reducing its ability to trap small particles effectively. 2. Risk of Tears: The force exerted by compressed air can potentially cause small tears or damage to the filter material, compromising its integrity. 3. Dust Resuspension: Compressed air can blow trapped dirt and dust back into the air stream, which might then be recirculated through the system. Proper Cleaning Methods Tap Method: Gently tap the filter against a solid surface to dislodge loose dirt and debris. Replacement: If the filter is heavily clogged or damaged, it should be replaced rather than cleaned.   Our filters are equipped with differential pressure indicators. The indication area of ​​the differential pressure gauge consists of two colors: green and red. When the pointer is in the green area, it means that the filter element does not need to be replaced. When the pointer points to the red area, the filter element needs to be replaced.   What are the consequences of not replacing the filter element? 1、Corrosion of gas storage tanks and transmission network pipes 2、Block valves and freeze valves and air motors 3、Low production efficiency, increased manufacturing costs, increased downtime  

What should you pay attention to when using an automatic drainer

  The automatic drainer is one of the key components for removing condensation water. However, although the automatic drain plays an important role in the dryer system, it is also the most prone to failure. In order to ensure the normal operation of the Refrigerated air dryer and avoid the impact caused by drain failure, it is particularly important to understand the working principle and daily maintenance of the automatic drain.     How the automatic drainer works   The main function of the automatic drainer in the Refrigerated air dryer is to drain the condensed water in time. During the working process of the Refrigerated air dryer, the water vapor in the compressed air will condense into water due to the temperature drop. This water contains impurities, such as dust, oil, rust, mud, etc., so the discharged water is not clean water, but A thick liquid containing solid impurities and oil.   why automatic drainers are prone to failure The main reasons are prone to failure are as follows:   1. Impurity clogging: The water discharged from the cold dryer is usually mixed with solid impurities, such as dust, rust, mud, oil, etc. These impurities will enter the drain along with the water flow. Although the automatic drainer is equipped with a filter, if the filter is not cleaned in time, oil and impurities will gradually accumulate, causing the drain outlet to become blocked. Blockage will prevent the water from flowing out smoothly and affect the normal drainage function of the dryer.   2. Insufficient pressure: The automatic drain requires a certain amount of air pressure to work properly. If the working pressure of the refrigeration dryer system is too low, the automatic drain may not be started or air leakage may occur, preventing the condensation water from being effectively discharged. Being in a low pressure state for a long time may also cause damage to the drain parts.   3. The temperature is too low: In cold environments, condensation water may accumulate in the water storage cup of the automatic drainer. If this water is not drained out in time, freezing may occur in low temperature environments. Freezing will not only cause the drain to become clogged, but may also cause the water storage cup to break, or even damage other parts of the drain. Therefore, when the operating temperature of the cold dryer is below zero, special attention should be paid to the maintenance of the drainer.   4. Overpressure problem: The automatic drainer is designed with a rated working pressure range. If the air pressure in the system exceeds the rated pressure of the drain, it may cause the water storage cup to rupture or damage other components. Excessive pressure will cause the automatic drainer to bear excessive workload and affect its service life.     The automatic drainer is a vital component of the cold dryer system. Its normal operation is directly related to the stability of the system and the drying effect of the compressed air. During use, in addition to ensuring the normal air pressure and temperature of the system, users should also perform regular maintenance on the automatic drain, especially cleaning the filter, checking sealing and preventing freezing. These daily care and maintenance measures can effectively avoid automatic drain failure, extend the service life of the equipment, improve the operating efficiency of the cold dryer, and ensure the normal operation of downstream equipment.

Compressed air purification solution (refrigerated air dryer)

  Compressed air often carries a variety of pollutants, including moisture, oil, solid particles and harmful chemical impurities, which seriously affect system performance and equipment life. Solid particles and oil will clog cylinders and pipes, causing system pressure to drop and pneumatic components to fail; and moisture not only corrodes metal parts and causes pneumatic components to fail, but also freezes in cold environments, causing pipes to freeze and crack. Therefore, deep purification of compressed air is an indispensable part of industrial production. Efficient compressed air purification has far-reaching effects such as reducing equipment loss, avoiding product pollution, improving product quality, ensuring a healthy working environment, and preventing occupational diseases.   1. Reference plan for compressed air purification system selection (cold dryer) Hongrijia YUKA has been deeply involved in the field of compressed air purification for more than 20 years. With its professional technical strength and rich industry experience, it provides customers with personalized and efficient compressed air solutions.   Different processes have different requirements for the dew point temperature of compressed air. For example, the pressure dew point of compressed air used for instruments is generally required to be below -40°C, while the pressure dew point of compressed air for semiconductor chip factories is required to be -70°C. However, in most cases, it is sufficient to require the dew point temperature of compressed air to be above 0°C. The dew point requirement of compressed air is usually achieved by a refrigerated dryer. Cold dryer is the abbreviation of refrigerated dryer. The working principle is to use refrigerant to exchange heat with compressed air, reduce the temperature of compressed air to a dew point temperature in the range of 2-10°C, and remove moisture (water vapor component) in the compressed air.   By cooling and cooling, the water vapor in the compressed air is condensed into droplets, thereby achieving the purpose of reducing the moisture content. The condensed droplets are discharged from the machine through the automatic drainage system.   Automatic drainage system   2. Advantages of YUKA cold dryer--HHL series integrated refrigerated dryer   1.

YUKA compressed air fiter’s features

YUKA has developed a mechanical hand-integrated draining decice,thereby reducing energy waste and babor costs.   1. High performance filter media YUKA condensing and dust removal compressed air precision filters use high-efficiency borosilicate glass nanofiber materials with 95% porosity,which provide excellent filtration efficiency and extremely high dust holding capacity. Strong impact strength!   2.Wound and folding composite filter media filter YUKA precision filter cartridges are constructed using a unique process-wound and folding filter media filter,winding technology and deep folding technology. The folding increases the filter area by approximately 450% compared to conventional wound precision filter cartridges.Compared with ordinary other folding precision filter cartridges,the filter area is increased by about 200%,thereby improving the service life and reducing the presure difference and improving the filtration performance.   3.Filter media is specially treated YUKA precision filter caridges are specially treated to provide oleophobic and hydrophobic properties to prevent liquid from adhering to the fibers of the filter media.This technology ensures that the dust space of the filter media of the precision filter is not occupied by the condensate,which reduces the pressure loss and energy consumption of the system.Compared to conventional filters ,YUKA’s coalescing filter combines multiple oleophobic and hydrophobic methods to ensure high performace and drainage capacity.The traditiona ordinary filter is difficult to achieve the above functions.   4.Advanced airflow control technology The upper and lower body structures of the YUKA filter housing are integrated into noe body. The upper body part is collectively referred to as the tube head,the lower body is the tube dody, and the inlet of the tube head is desighned as a “horn” shape to reduces the resistance caused by gas turbulence; full flow desigh The nozzle is more airy.The new design replaces the old 90 degree straight angle with a diversion elbow inside the tube head,which greatly reduces the generation of turulence.The inlet guide elbow is increased from small to large filter,which can greatly reduce the preesure loss.An internal gas flow distributor is arranged on the upper part of the filter element , and the flow distributor can reduce the turbulent flow and effectively distribute the compressed air passing through the filter element, thereby improving the distribution efficiency of the air inside the filter element, so that the filter element can increase the filtration area and reduce the pressure drop.Howerver,the conventional ordinary filter is unevenly distributed ,so that the lower “wet band”in the middle of the filter element is occupied by the nubalanced filter medium and cannot be filtered.   5.Compact:lighweight and fully corrosion resistant Advanced desigh concepts make precision filters more compact and lighter.All YUKA precision filter housings are cleaned ,degreased and specially preserved prior to sprayinng .Special processing provides excellent corrosion protection.All of the precision filter housings are coated with a strong, durable epoxy coating on the outer curface to further provide corrosion protection for the housing. YUKA precision filter housing provides 15 years of qualiy assurance,while ordinary filters begin to rot after noe to two years of use,which in turn leads to safety problems and secondary air pollution.   6.differential pressue indicator/differential pressure gauge Due to the filter under different working conditions,after the filter medium and water have reached a certain service life,the filter element is occupied by the intercepting medium and causes the pressure difference after filtering, and the differential pressure indiactor plays an important role. Accuate instructions to remind you to change the maintenance,thus avoiding the serious impact of the gas source pollution.   7.Liquid level mirror Since the copmpressed air contains a large amount of water and oil, the fitered liquid condenses on the surface of the filter element, and the liquid itself is stored in the static area of the filter housing and the filter gap.At this time,the liquid level mirror plays an important role. Sexual effect to see if the liquid inside the filter is within the standard range, to avoid excessive liquid being sucked into the air pipe again.   8.Manual and automatic integrated drain device The liquid discharge device is collectively referred to as a drain in the market. In order to ensure the quality of the gas source,the liquid discharge device plays a key role in the whole filter purification system, and all the filtered liquid and fine impurites are discharged to the outside through the liquid discharge device.However,the automatic liquid discharge device is likely to be disabled due to serious pollution in the long-term and the daily artificial discharge is caused by human negligence.
