Liugong SP254917 Pre-filter: It intercepts and removes impurities upfront, protecting the main filter and reducing costs.

At mine blasting sites and during loading operations at sand and gravel yards, the large number of sand and gravel particles and fibrous impurities suspended in the air are the primary targets for filtration components. “ Number one natural enemy ” If these large particles enter the main filter element directly, they will quickly clog the filter material’s pores and wear down the filter layer structure, significantly shortening the replacement cycle of the main filter and driving up operation and maintenance costs. LiuGong. SP254917 Pre-filter, as part of the filtration chain “ Frontline defense ” Specifically designed to intercept large-particle pollutants, serving as the primary filter element for the downstream stage. “ Reduce Burden, Provide Support ” , becoming the filtration system for construction machinery “ Great partner for saving money ”。

Factory-precise fit: Tight-fitting installation, no dead corners for leaks or spills.

The sealing and fit of the prefilter directly determine the effectiveness of front-end interception, LiuGong. SP254917 Developed entirely based on the filter system layout specific to a particular aircraft model: The overall dimensions precisely match the pre-filter installation compartment, allowing for seamless integration without any cutting or modification. After installation, the gap between the filter and the compartment is less than— 0.2mm The thread pitch and precision of the interface match exactly those of the main filter connection end. After tightening, the fit is tight and secure with no looseness, effectively eliminating non-genuine pre-filters. “ Misalignment of the interface causes dust leakage on the side. ” the issue; featuring a built-in quick-release latch design, allowing maintenance personnel to secure it effortlessly by hand—entire replacement process takes no more than 10 Minutes—easily completed during construction breaks. “ Frontline defense ” Upgrade.

Cyclonic grading and dirt filtration: First spin, then block—greatly reduces the main filter's pressure load.

For construction machinery “ Large particles, high concentration ” the pollution characteristics, SP254917 Adopt “ Cyclonic separation + Coarse filtration interception ” Double-preconditioning process: The top cyclonic flow guide structure utilizes centrifugal force to... 60% Above diameter > 10 μm Sand and gravel particles, dead leaf impurities “ Shake off ” The airflow is directly discharged through the exhaust port, reducing the impact of large particles on the filter material at the source. The remaining tiny impurities are then further filtered by a coarse polyester fiber layer at the bottom, which provides a second stage of interception and finer filtration based on particle diameter. 5-10 μm The pollutants are effectively removed, leaving only a small amount of ultrafine dust in the air that enters the main filter element. Measured results show that after installing this pre-filter, the dust-holding capacity of the main filter element is reduced. 50% , extended replacement cycle 1.2 More than double.

Low-resistance ventilation design: Blocks without holding your breath, efficiency remains uncompromised.

If the pre-filter has excessive air resistance, it can lead to poor airflow or oil flow, thereby affecting the equipment's operational efficiency. LiuGong. SP254917 Achieved through structural optimization “ High-efficiency interception and low-resistance flow ” Balance: The vortex guide chamber features a streamlined design that smoothly directs airflow into rotation, thereby avoiding resistance losses caused by localized vortices. The coarse filter layer adopts a large-aperture mesh structure that not only traps large particles but also increases the air permeability area compared to conventional pre-filters. 40% Actual measurements show that the ventilation resistance of this prefilter is only a fraction of the industry standard. 60% Ensure that, during high-load operations, the intake or oil flow remains unobstructed and power output remains stable.

Weather-resistant and durable: Withstands harsh conditions for longer-lasting use.

Facing the dusty, vibrating, and high- and low-temperature operating environments of construction machinery, SP254917 Specifically upgraded for durability: The casing is made of high-strength material. ABS Engineering plastics, after -35℃ To 90℃ The high- and low-temperature cycling test showed no brittle cracking or deformation, enabling the device to withstand both the severe cold of northern regions and the scorching heat of southern regions. The internal cyclone blades are equipped with additional reinforcing ribs, allowing them to endure the high-frequency vibrations caused by equipment jolting and preventing structural loosening that could reduce separation efficiency. The coarse filter layer is made of oil- and dirt-resistant materials; when slightly contaminated, its performance can be restored simply by reverse-blowing with compressed air, eliminating the need for frequent replacements. In the highly dusty environments of mining operations, its effective service life can be several times longer than that of conventional pre-filters. 1.5 Twice.

End-to-end quality control: Proactive protection standards, with traceable quality.

LiuGong vs. SP254917 Execute “ Pre-filter stage ” Strict quality control: The casing material must pass impact resistance testing to ensure no damage even when struck by sand and gravel. Each batch of products undergoes sampling for cyclone separation efficiency testing and air flow resistance measurement to verify that core performance meets the standards. At the finished-product stage, we simulate real-world operating conditions of the equipment for further testing. 300 Hourly dust load joint testing ensures stable interception performance. Each pre-filter is equipped with a unique, factory-originated traceability code; scanning this code allows you to check the production batch and inspection reports, completely eliminating counterfeit products. “ Interception failed. ” Potential hazards.
