Field data confirms that engines equipped with the Shacman WP12 Oil-Gas Separator Group consistently deliver lower total cost of ownership. Efficient oil separation reduces oil consumption, prevents turbocharger fouling, and extends the service life of the diesel particulate filter, contributing to significant operational savings for fleet managers.
Trusted by operators in more than 60 countries, the Shacman WP12 Oil-Gas Separator Group is a global benchmark for heavy‑duty crankcase ventilation reliability. Its proven design and robust construction make it a cornerstone of modern commercial vehicle emission systems.
The oil‑gas separator shell assembly is precision‑moulded from high‑temperature reinforced polymer or aluminium, featuring internal baffles and flow channels that direct crankcase gases through the coalescing element. Its robust design withstands engine vibration and thermal cycling, ensuring a long service life.
The oil‑gas separator element is made from high‑efficiency synthetic media with a precisely calibrated pore size, effectively capturing oil droplets as small as 1‑2 microns while maintaining low pressure drop. Its pleated design maximises surface area for extended service life, and it is equipped with an integral drain valve to return separated oil to the crankcase.
The shell assembly includes all necessary mounting points, O‑rings, and fastening features for a direct, leak‑free installation. Its internal design ensures that the element is correctly positioned and sealed, preventing bypass of unfiltered gases.
The group is supplied as a complete kit with the shell and element pre‑matched, ensuring a perfect seal and optimal performance. Installation is straightforward with basic hand tools, and detailed torque specifications are provided for accurate assembly.
This oil‑gas separator group is an essential maintenance component for any WP12 engine, offering improved crankcase ventilation, reduced oil carryover, and enhanced emission compliance. Its genuine Shacman quality ensures that your engine continues to deliver reliable performance and meets the strictest environmental standards.
Oil‑gas Separator Shell Assembly – The main housing that encloses the separator element and directs crankcase gas flow through the filtration media. Manufactured from high‑temperature reinforced polymer or aluminium with a corrosion‑resistant coating, this shell features integrated inlet and outlet ports, internal baffles, and a sealing surface that accommodates the element and O‑rings. Its design ensures that gases are evenly distributed across the element surface, maximising separation efficiency while minimising pressure drop. The shell includes mounting bosses and bolt holes for secure attachment to the engine or bracket. Its robust construction withstands high vibration and thermal cycling, ensuring a long service life. This shell assembly is a direct replacement for the original factory unit, ensuring identical flow characteristics and durability. It is critical for maintaining proper crankcase pressure and preventing oil mist from escaping into the atmosphere or intake system.
Oil‑gas Separator Element – The consumable filtration media that captures oil mist and aerosols from crankcase gases, ensuring clean air is returned to the intake system. Manufactured from high‑efficiency synthetic fibres with a precisely calibrated pore structure, this element effectively captures oil droplets as small as 1‑2 microns while maintaining low flow resistance. Its pleated design provides a large surface area, allowing for extended service intervals and high dirt‑holding capacity. The element is reinforced with a perforated core and end caps, and includes an integral drain valve or wicking material to return collected oil to the sump. This element is designed to meet or exceed original equipment performance standards, effectively reducing oil carryover and protecting the turbocharger and DPF. Regular replacement with genuine Shacman elements is essential for maintaining separation efficiency and engine protection. This element is supplied as a complete unit, ready for installation into the shell assembly.
