New Energy Power parts filter element QXAC4P-4G602-500-01

Built to eliminate micro-contaminants and ionic impurities from high-sensitivity new energy system fluids (e.g., hydrogen fuel-cell deionized coolant, high-voltage inverter dielectric fluid), this filter element features a 4-stage advanced filtration media. The first stage (glass fiber pre-filter) captures large particles (≥20μm) to prevent media clogging; the second stage (synthetic micro-fiber layer) achieves 1μm absolute filtration accuracy, removing 99.95% of fine debris (e.g., carbon deposits, metal shavings) that could scratch fuel-cell bipolar plates or inverter capacitors. The third stage (ion-exchange resin layer) reduces ion content to ≤0.05μS/cm, preventing electrical leakage in high-voltage systems; the fourth stage (hydrophobic membrane) absorbs residual moisture (up to 1.2g/g of media weight) to avoid coolant emulsion. With a dirt-holding capacity of 280g, it extends replacement intervals to 25,000 operating hours—50% longer than standard filters—reducing maintenance frequency for fleet operators

Engineered to endure the ultra-high-pressure environments of heavy-duty new energy systems (continuous operating pressure: 30bar, peak pressure: 40bar), the filter element integrates a reinforced structural framework. The filtration media is pleated into 120 high-density folds (15mm pleat height) and bonded to a thick-walled polyamide core (tensile strength ≥40MPa) using high-temperature-resistant epoxy resin (resistant to 160℃). This design prevents media displacement or collapse under extreme pressure, ensuring consistent flow even during system startup or load peaks. The outer casing is made of glass-fiber-reinforced nylon 66 (UL94 V-0 flame-retardant), which resists deformation from temperature fluctuations and chemical corrosion. The flange interface is sealed with a dual-lip Viton gasket (shore hardness 80±5A), achieving zero bypass leakage—critical for avoiding unfiltered fluid entering precision components like hydrogen fuel-cell stacks or 800V inverter modules

Designed to perform reliably in the diverse and harsh operating environments of heavy-duty new energy trucks, the filter element offers exceptional temperature and chemical resistance. It maintains stable filtration performance across a wide temperature range: -45℃ (cold-start conditions in frigid northern regions) to 150℃ (continuous operation in high-temperature hydrogen fuel-cell systems), avoiding media brittleness at low temperatures or gasket softening at high temperatures. The filtration media and structural materials are compatible with all common high-power new energy fluids, including deionized water for hydrogen fuel cells, dielectric fluid for 800V inverters, and synthetic coolant for high-voltage motors—resisting chemical degradation (oxidation, hydrolysis) for over 25,000 hours. In salt spray tests (ASTM B117), the flange’s nickel-plated surface shows no rust after 800 hours, ensuring durability in coastal or high-humidity areas; it also resists road salt and industrial contaminants, making it suitable for construction or port logistics scenarios

Optimized for efficient maintenance in heavy-duty fleet operations, the filter element features an intelligent design that simplifies replacement and monitoring. It is equipped with an integrated pressure differential sensor port (compatible with OE system BMS) that transmits real-time clogging data to the vehicle’s dashboard, alerting technicians when replacement is needed (recommended at 2.5bar differential pressure). The flange-type mounting interface uses quick-release locking bolts that can be tightened or loosened with a standard socket wrench—no specialized tools required. The filter’s outer surface is labeled with clear identifiers (part number, fluid type, replacement interval, and safety warnings) for easy identification, reducing the risk of incorrect installation. Weighing 3.2kg (balanced for easy handling), it can be replaced by a single technician in 15 minutes or less. Additionally, the element’s media is recyclable (metal-free, polyamide core), aligning with new energy vehicles’ sustainability goals while minimizing environmental impact
