21368879 High-Efficiency Crankcase Breather
Professional Oil-Gas Separation for Volvo, Perkins & Heavy-Duty Engines
The Logical Role of Crankcase Filtration
In modern internal combustion engines, "blow-by" gases-a mixture of unburned fuel, air, and oil mist-leak past the piston rings into the crankcase. The 21368879 Crankcase Breather Filter serves as the critical logical gateway in the Closed Crankcase Ventilation (CCV) system. Without high-precision filtration, this oil-laden gas would enter the intake manifold and turbocharger, leading to carbon buildup on intake valves and significant efficiency losses in the intercooler.
Utilizing Synthetic Melt-blown Media and advanced coalescing technology, the 21368879 element effectively separates oil aerosols from the gas stream. This ensures that only clean air is recirculated into the engine's intake, while captured oil droplets are recycled back to the oil pan. This process is vital for maintaining Pressure Pulsation Resilience within the crankcase, preventing seal blowouts and ensuring the vehicle meets the strict ISO 19438 Standard for environmental protection and engine health.
1. Microfiber Coalescing Media
Our media features high-efficiency synthetic fibers that trigger the "coalescence effect." Small oil droplets merge into larger ones as they pass through the gradient layers, achieving a high Beta Ratio for particulate separation.
2. Low Air Resistance Design
Engineered to minimize backpressure, this filter allows the engine to "breathe" freely. This prevents excessive crankcase pressure, which can lead to oil leaks at the crankshaft seals and turbocharger oil return lines.
3. Metal-Free Support Frame
The "Eco-friendly" metal-free design is fully incinerable, reducing environmental impact during disposal. Despite being lightweight, the polymer frame provides excellent structural rigidity against high-velocity airflow.
4. Dual Elastic Sealing
Equipped with a dual-stage elastic sealing structure, this filter prevents untreated blow-by gases from bypassing the media. It maintains an airtight fit even under the extreme thermal expansion of heavy-duty engine operation.

Expert Maintenance Tip: A clogged breather filter leads to increased oil consumption and potential engine oil leaks. In heavy-construction or high-load agricultural use, we recommend inspection every 500 hours to ensure the turbocharger blades remain free of oil residue.
Frequently Asked Questions
Q1: Will the synthetic media deform under high engine temperatures?
A: No. Our 21368879 filter uses high-grade heat-stabilized synthetic fibers and a temperature-resistant polymer frame. It maintains its shape and filtration efficiency even during continuous heavy-duty operation at high thermal loads.
Q2: How does this filter protect my turbocharger?
A: It removes oil mist from the blow-by gas. Without this, oil would coat the turbocharger compressor wheel, causing imbalance, reducing boost efficiency, and eventually leading to turbocharger bearing failure.
Q3: Is this a perfect replacement for the Perkins 2652A016?
A: Yes. It is manufactured to exact OEM dimensions and specifications. It is 100% interchangeable with Perkins 2652A016 and 2656A016 without any modification to the engine housing.
Q4: Why should I choose the "Eco-friendly" metal-free design?
A: Metal-free filters are easier to dispose of and recycle. They are also lighter and eliminate the risk of internal corrosion flakes entering the oil pan in high-humidity environments.
Q5: What are the signs of a failing breather filter?
A: Common symptoms include blue smoke from the exhaust, excessive oil film inside the turbo intake, high oil consumption, and oil leaking from gaskets due to increased internal crankcase pressure.
