GXNGL series high temperature resistant and efficient partition air filter element

The GXNGL series high temperature resistant and efficient partitioned air filter element is a core component designed for end air purification in high temperature and clean working conditions. Relying on a high temperature resistant material system and a partitioned stable structure, it can effectively intercept particles of 0.3 μ m and above in high temperature environments for a long time. As the final filtering barrier of the high temperature and clean system, it ensures that the air cleanliness in the high temperature supply or exhaust process meets the standard, solves the pain point that ordinary high-efficiency filters cannot operate stably in high temperature conditions for a long time, and provides reliable end purification support for various industrial scenarios that have dual requirements for air cleanliness and operating temperature.

The GXNGL series high temperature resistant and efficient partitioned air filter element frame is made of high temperature resistant stainless steel or galvanized steel plate material, with high temperature resistant aluminum foil or stainless steel corrugated plate as the partition plate inside. The ultra-fine glass fiber filter material is evenly divided into equidistant pleats to ensure that the airflow passes through each layer of filter material evenly. The sealing part is bonded with high temperature resistant inorganic adhesive or fluorosilicone gel, which will not cause the problem of adhesive layer flowing or cracking in high temperature environment. The overall conventional temperature resistance level covers the range of 250 ℃ to 350 ℃, and the special customized version can adapt to higher temperature conditions. The filtration efficiency is stable up to H13-H14 level, and the flange or standard frame structure is suitable for the installation interface of most high temperature purification equipment. The front and rear of the filter material are reinforced with high temperature resistant metal mesh to avoid high-pressure airflow impact. The lower filter material is damaged and deformed.

The GXNGL series high-temperature resistant and efficient partitioned air filter element is widely used in clean air supply systems for industrial high-temperature ovens, sterilization tunnels, and heat treatment furnaces. It can also be used for exhaust purification in high-temperature processes of semiconductor manufacturing, air purification in high-temperature drying lines of the coating industry, and air supply in high-temperature clean production lines of food processing. At the same time, it is suitable for intercepting particulate matter in the front end of incinerator exhaust gas, and clean air supply in special high-temperature test chambers, providing stable end filtration guarantee for air purification needs in various high-temperature environments.

The GXNGL series of high temperature resistant and efficient air filters with partitions have a full chain of high temperature resistant material systems that have been specially adapted. The filter material, partition, sealant, and outer frame components will not experience aging, deformation, or failure at rated high temperatures, and their long-term operational stability is far superior to that of ordinary high-efficiency filters; The airflow distribution with partition structure is more uniform, the dust holding capacity is excellent, and it can still maintain a longer service life under high temperature and high dust conditions; The overall filtration efficiency is stable, and there will be no problem of filter fiber shedding or rapid efficiency degradation in long-term high-temperature operating environments; The modular structure has strong adaptability and can directly replace conventional high-efficiency filters of the same size without the need for structural modifications to the original high-temperature purification equipment.

After running for a period of time, the resistance of the GXNGL series high temperature resistant and efficient partition air filter element increases too quickly, mostly due to the failure of the front-end pre filtration process. A large amount of large particle impurities directly enter the high-efficiency filter material, causing rapid blockage. Timely troubleshooting and replacement of the pre primary and medium efficiency high temperature resistant filters are necessary. If the resistance has reached twice the initial value, a new filter element needs to be replaced; Under high temperature conditions, if there is air leakage at the sealing position, stop the machine and cool it down. Check if the sealant cracks and if the sealing gasket is aging. Clean the sealing surface and replace it with a suitable high-temperature resistant seal to restore airtightness; If the cleanliness after filtration does not meet the standard, check whether there is local damage to the filter material and whether there are gaps in the installation frame. If there is structural damage to the filter material, replace it with a new filter element directly; After the first heating operation, the resistance was abnormally high, mostly due to failure to follow the standard step-by-step heating and curing of the adhesive layer after installation. After stopping the machine, the curing process was completed again according to the standard heating curve to return the resistance to the normal range.
