AS2474Air Oil Separator Filter

AS2474 is a high-efficiency air oil separator filter applied to heavy-duty commercial vehicle and engineering machinery diesel engines. It serves as the core component of engine crankcase ventilation CCV system, adopting multi-layer composite filter material to separate fine oil mist from blow-by gas thoroughly. It effectively reduces engine oil burning, prevents oil vapor from entering intake pipeline and turbocharger, keeps intake system clean, lowers exhaust emissions and extends engine and turbocharger service life. With excellent dust holding capacity and separation efficiency, it remains stable under long-time high load, high temperature and plateau working conditions, no blockage, no oil leakage and stable ventilation performance.

①Applicable Vehicles: Suitable for DAF, IVECO, Cummins supporting heavy trucks, semi-trailers, construction machinery, generator sets; compatible with Sinotruk, Shaanxi Delong, Foton Auman series commercial vehicles.

②Adaptable System: Perfectly matched with original crankcase ventilation pipeline, hose and mounting base, no cutting or modification required for direct assembly.

③OE Reference Number: AS2474

④Interchangeability: Consistent with original installation size, thread interface and fixing position. Direct replacement without changing brackets and pipelines, saving maintenance time and labor cost.⑤Value-added Service: Support model, engine version matching confirmation; provide installation steps and daily maintenance guidance.

Core MaterialsFilter shell adopts high-strength cold-rolled steel plate with pressure resistance and deformation resistance. Internal filter medium uses imported glass fiber composite filter paper, featuring high oil mist separation rate, large dust holding capacity and not easy to deform. Inner support mesh is made of galvanized steel for anti-rust and structural reinforcement. Sealing ring adopts high-temperature and oil-resistant nitrile rubber, good compression resistance and tight fit to avoid air leakage. Central support tube uses high-strength plastic, corrosion-resistant and stable structure.

Surface Treatment

Shell surface is electrophoresed and painted for anti-corrosion, rust-proof and scratch resistance. Filter paper is fixed with high-temperature resistant glue, no degumming under extreme temperature. Thread interface precision turning, smooth and firm installation. Sealing surface fine grinding to ensure fit tightness.

Adopt full-automatic folding and winding process for filter medium, uniform fold and stable flow rate. Integrated hot pressing sealing technology to prevent gas shortcut. Each finished product passes air tightness test, separation efficiency test and pressure resistance test before delivery. Strict production process controls internal cleanliness to avoid impurity residue.

①Quality Grade: OE replacement level, fully in line with original factory matching standard. Passed 500-hour high temperature and high load bench test, adapt to mountainous area, plateau, mining and harsh road conditions.

②Inspection Items: Air tightness detection, oil mist separation efficiency, pressure drop test, appearance size inspection, raw material sampling test.

③Quality System: Compliant with ISO9001 and IATF16949 quality management system, whole process production quality control.

④Batch Tracking: Laser marking part number AS2474, batch code and production date, complete record for after-sales traceability and quality follow-up.

①Average Service Life: It can be used for 20,000 to 30,000 kilometers, or about 12 months, which fits the regular maintenance cycle of most engines, so you don't have to replace it frequently.

②Performance Advantages: It's really good at separating oil mist from gas-way better than ordinary filters. This helps cut down on engine oil waste effectively. It keeps crankcase ventilation pressure stable, avoiding overpressure inside the crankcase. It also prevents oil contamination on turbochargers and intercoolers, cuts down carbon deposits in the intake system, and lets the engine work in better condition.

③Harsh Environment Adaptability: It works well no matter how tough the environment is-whether it's super cold, down to -40℃, or extremely hot, up to 120℃. It can stand dust, humidity, and corrosive gas too. Even when used in mining areas, logistics transportation, or on plateaus, it still maintains good filtration performance without any issues.

Q1: What engines and trucks does AS2474 fit?

A1: It fits Cummins, DAF and IVECO diesel engines. Most of the mainstream heavy trucks and construction machinery can use it. Just tell us your engine model, and we'll check if it's a perfect match for you.

Q2: What will happen if the oil separator filter is not replaced in time?

A2: It will cause poor crankcase ventilation, increased oil consumption, easy carbon deposition in intake pipeline, and even affect turbocharger service life.

Q3: Support foreign trade customized packaging and documents?

A3: Yes, we provide neutral packaging, OEM LOGO customization, and complete export documents for customs clearance.

Q4: Is there spot stock for bulk order?

A4: Regular models have sufficient inventory, can meet large quantity delivery at any time, and support long-term contract supply.

Installation RequirementsCheck the appearance and sealing ring integrity before installation; clean the installation base and pipeline impurities; screw it vertically and tighten it with standard torque to avoid over-tightening thread damage; keep the ventilation pipeline unobstructed after installation.

Regular InspectionCheck for oil leakage and air leakage every 8000km; inspect filter blockage status every 15000km; replace timely when oil consumption obviously increases or ventilation is not smooth.

Storage RequirementsStore in dry and ventilated warehouse, avoid damp and heavy pressure; keep original packaging sealed, shelf life 1 year; do not place with corrosive chemicals.

Replacement TipsIt is recommended to replace together with engine oil filter and air filter during routine maintenance; choose original standard separator filter to avoid inferior parts causing engine failure.
