Lifelt filter core technology breakthrough reshaping the industry pattern

Xinxiang, Henan, August 2024 - In the field of industrial filtration, a wave of technological substitution is quietly setting off. Henan Xinxiang Lifelte Filter Co., LTD. (hereinafter referred to as "Lifelte") with its self-developed "ultrafiltration series" filter element **, successfully broke the monopoly position of international giant PALL (PALL) in the high-end filtration market, and provided more competitive filtration solutions for China's manufacturing industry with the dual advantages of performance benchmark and cost optimization.

Breakthrough of technical barriers: comparable to the international standard "ultrafiltration series" for a long time, PALL filter element with high precision filtration, long life and other characteristics occupy the global market, but its high price and supply cycle has become a pain point for domestic enterprises. Since 2018, Liffert has invested more than 100 million yuan in research and development funds to reverse engineering and technological innovation for PALL core products, and finally launched the "ultrafiltration Series" filter element that is 100% compatible with PALL specifications. Using nanocomposite fiber membrane technology, the series offers a filtration accuracy of 0.1 micron (on par with PALL's flagship HC series), while extending service life by 30% through a pulsed backwash design. According to the data of third-party testing institutions, in the continuous operation of 5000 hours of testing, the pressure drop stability and impurity interception rate of the "ultrafiltration series" filter element are better than that of the same type of PALL products.

"Instead of simply mimicking, we used materials science to reconstruct the filtration efficiency." According to Wang Peng, chief engineer of Liffert, the team's original gradient aperture structure reduces the resistance of the filter element when intercepting large particle pollutants by 40% in the initial stage, and maintains high throughput in the later fine filtration stage, effectively solving the industry problems of "short life and easy blockage" of the traditional filter element.

The double advantage of cost and service: Customer cases confirm the cost performance at the price level, Lifelter's "ultrafiltration series" pricing is only 60% of PALL similar products, and provides the first "three-year warranty + free replacement" ** service policy. This strategy quickly gained market response: After a Shandong steel group replaced all production lines with Liffert filters in 2023, the annual maintenance cost was reduced by 45% and the equipment failure rate was reduced by 23%; Medical device manufacturer Mindray Medical has reduced the cost of aseptic filtration by 35% through cooperation to customize the filter element

"In the past, we were constrained by the supply cycle of imported filters, and urgent orders were often delayed." "Lifelt's localised supply chain and quick response service have completely freed us from the dilemma of 'stuck neck'," said Zhang Qiang, manager of Shandong Iron and Steel's equipment department. At present, the national "Industrial base reconstruction Project" clearly proposes the goal of "the localization rate of key components to increase to 80%", and the filtration industry as an industrial base link, its autonomy process has attracted much attention. Relying on the advantages of Xinxiang "filtration industry cluster", Lifelte has built the largest automatic filter production line in Asia, with a monthly production capacity of 200,000 pieces, covering eight fields such as petroleum, chemical, pharmaceutical and food. Industry analysts pointed out that Liffert's technological breakthrough not only filled the gap of domestic high-end filter elements, but also forced international brands to adjust their pricing system through the "performance benchmarking + cost dimension reduction" strategy. Recently, PALL's sales department in China has started price adjustment, and some models have fallen by 15%

From technological breakthrough to market reconstruction, the rise of Lifeldt filter confirms the depth of possibilities of domestic substitution. In the wave of autonomy of the industrial base, this case not only provides a new path for the manufacturing industry to reduce costs and increase efficiency, but also reflects the transition trajectory of China's manufacturing from "quantitative change" to "qualitative change".
