Industry Pain PointsThe aerospace and transportation sectors impose extremely stringent standards on filter elements in terms of reliability, safety and airworthiness compliance. Aircraft avionics bays house precision electronic equipment including flight control computers, navigation systems and communication systems, which are highly sensitive to particulate contaminants and humidity. Tiny dust particles may trigger short circuits on circuit boards, while excessive humidity leads to condensed water corrosion of electronic components.The passenger cabin is an enclosed space. Failure to efficiently filter airborne aerosols, bacteria and viruses will drastically raise the risk of cross-transmission of respiratory illnesses.If the oxygen concentration in the ullage space above fuel tanks exceeds the safe threshold, fuel tank explosions may occur upon exposure to static sparks or high-temperature heat sources, posing a direct threat to flight safety.Solutions & ApplicationsClean & Dry Air for Environmental Control SystemsPre-filter air filter cartridges and air water removal filter cartridges deliver dust-free, dry cooling air to aircraft avionics bays to avoid corrosion and short-circuit failures of precision circuit boards.Cabin Air SafetyAircraft cabin HEPA filters trap particles larger than 0.3 μm with a filtration efficiency of ≥99.97%, enabling rapid cabin air renewal and effectively mitigating virus transmission risks.Fuel Tank Fire SuppressionMulti-stage filter assemblies for Nitrogen Generation Systems (NGS) feature four pretreatment processes: particulate filtration, coalescing oil removal, ozone catalysis and activated carbon adsorption. These units eliminate oil mist, solid particles, ozone and volatile organic compounds from engine bleed air to protect downstream hollow-fiber Air Separation Membranes (ASM). High-purity Nitrogen-Enriched Air (NEA) generated via the membranes is injected into fuel tank ullage spaces to eliminate explosion hazards at the source.Typical Application ScenariosVentilation systems for avionics bays, cabin recirculation air systems and fuel tank inerting systems of civil airliners, general aviation aircraft and business jetsVentilation filtration for rail transit traction control systems and air purification for electrical control cabinets

Industry Pain PointsSemiconductor manufacturing imposes extremely strict cleanliness requirements. As process nodes shrink to 7 nm, 5 nm and even 3 nm, the sensitivity of wafer fabrication to airborne particles, airborne molecular contaminants (AMC), metal ions and trace impurities in ultra-pure water (UPW) rises exponentially.A single particle as small as 0.1 μm attached to a photomask may render hundreds of chips on an entire wafer defective. Metal ion contamination at the ppb level in photoresist alters the photosensitive properties of photoresist and causes line width shift. Ions such as boron and sodium at ppt levels in ultra-pure water are doped into oxide films during gate oxide formation, shifting threshold voltage and directly triggering electrical failure of chips.In addition, acid gases (HF, HCl, H₂SO₄), alkaline gases (NH₃), condensable organics (siloxanes, phthalates) and dopant gases (boron, phosphorus, etc.) present in fab cleanroom air will form haze residues or chemical stains on wafer surfaces, severely lowering product yield.Solutions & ApplicationsCleanroom Environment ControlWe supply a full lineup of cleanroom filters including pre-filters, medium-efficiency filters, sub-high-efficiency filters and ultra-high-efficiency filters to precisely maintain air cleanliness from ISO Class 3 to ISO Class 6 for wafer fabrication, packaging & test workshops and lithography zones.Process Equipment Supporting FiltrationOn-board HEPA/ULPA filter units are matched for lithography machines, etchers, PVD/CVD equipment and wet cleaning tools to shield core process chambers from particle contamination.High-Purity Chemical & UPW PurificationPTFE pleated filter cartridges, high-purity PP filter cartridges and ultrafiltration membranes are adopted for terminal fine filtration of photoresist, developer, etchant, CMP slurry and ultra-pure water, restricting metal ion leaching to below ppb levels.AMC (Airborne Molecular Contaminants) ControlTailored chemical filtration solutions are developed to meet stringent AMC standards for advanced nodes, efficiently removing acid gases, alkaline gases and condensable organics from process air.Typical Application Scenarios12-inch / 8-inch wafer fab cleanrooms (lithography, etching and thin-film areas)Lens purge microenvironments for lithography toolsCMP (Chemical Mechanical Planarization) slurry filtration systemsChemical circulation pipelines of wet etching equipmentTerminal polishing loops of UPW (Ultra-Pure Water) systemsGas purification modules for FOUP (Front Opening Unified Pod)

Industry Pain PointsThe energy, power, petroleum and chemical sectors operate under extreme working conditions including high temperature, high pressure, severe corrosion, heavy dust, flammable and explosive hazards.Across the full natural gas industrial chain from wellhead extraction, long-distance pipeline transportation to distribution at city gate stations, gas flow carries contaminants such as liquid hydrocarbons, water mist, compressor lubricating oil mist, pipeline rust and welding slag. These pollutants cause scaling on compressor blades, inaccurate flowmeter readings and regulator sticking; in severe cases, they can damage hot gas path components of gas turbines.In coal-fired power plants, turbine lubricating oil systems, DEH (Digital Electro-Hydraulic Control) servo valves and coal mill hydraulic loading systems demand ultra-high fluid cleanliness. The fitting clearance of servo valves is only 3–5 μm, and even tiny particles can result in spool jamming and control failure.In petrochemical production, catalyst loss, tray blockage and heat exchanger fouling in core equipment such as hydrogenation reactors, fluid catalytic cracking units and ethylene cracking furnaces directly impair long-cycle stable plant operation. When alcohol amine droplets from amine desulfurization systems are carried to downstream sections, they corrode pipelines and contaminate finished products.Solutions & ApplicationsDeep Purification for Full Natural Gas Industrial ChainCoalescer filter cartridges and separation filter cartridges are adopted to remove liquid hydrocarbons, water mist and solid particles from natural gas.

Industry Pain PointsHydraulic systems and heavy-load lubrication systems act as the power core of industrial equipment, and their operational reliability directly determines the continuous operation rate of production lines. Statistics show that approximately 80% of hydraulic system failures are caused by fluid contamination. Four major contaminants lead to system breakdown: solid particles, water, entrained air and sludge.The fitting clearances of hydraulic pumps, valves and cylinders generally range from 3 μm to 50 μm. Tiny hard particles such as iron filings and silica dust scratch the mating surfaces between valve spools and valve bodies, which may result in spool sticking and response failure. Water mixed into the oil emulsifies lubricants, accelerates the consumption of additives and causes corrosion on metal surfaces. Colloids and carbon deposits generated by oil oxidation block throttle holes and jam sliding valves.In heavy-load lubrication scenarios such as gearboxes and bearings, accumulated metallic wear debris (iron, copper, tin) aggravates gear pitting, spalling and bearing fatigue failure, which may trigger catastrophic equipment damage.In addition, under high-temperature working conditions with oil temperatures ranging from 80℃ to 180℃, including injection molding machines, die-casting machines, continuous casters and hot rolling lines, the filter paper adhesive of ordinary filter elements will soften and peel off, while sealing components harden and lose efficacy, resulting in reduced filtration precision and fluid leakage.Solutions & ApplicationsFiltration & PurificationOur lubricating oil filters and hydraulic filter cartridges adopt high beta values (βx ≥ 200), which can effectively remove metallic wear particles and carbon deposits from oil and accurately maintain oil cleanliness up to standard NAS grades.Adaptation to Harsh Working ConditionsWe supply high-temperature resistant hydraulic filter cartridges for high-heat working conditions such as continuous casting, hot rolling and injection molding, supporting stable filtration performance at operating oil temperatures up to 180℃.Cost-Effective Import SubstitutionWe provide interchangeable replacement oil filter cartridges compatible with global mainstream brands including Pall, HYDAC, MP Filtri, Parker, MAHLE and Donaldson. Our products deliver equivalent performance while drastically cutting customers’ operation and maintenance costs.Typical Application ScenariosHydraulic systems for construction machinery (excavators, cranes, loaders)Gearbox lubrication for metallurgical rolling millsLubrication of wind turbine gearboxesHydraulic systems of injection molding machines and die-casting machinesTurbine lube oil stations in power plantsMining machinery and marine power systems
