MANN-FILTER WH 1257/1 Oil Filter
The MANN‑FILTER WH 1257/1 is a high‑performance oil filter specifically engineered for utility vehicles and industrial hydraulic systems. Designed with precision engineering, it delivers reliable filtration across a wide range of operating conditions, ensuring optimal protection for engines and hydraulic components.
Key Design Features
- Robust Construction: The filter housing is made from durable materials that resist corrosion and withstand harsh environments typical of utility vehicles.
- High Filtration Efficiency: Capable of capturing particles as small as 0.5 µm, it maintains clean oil flow and protects critical engine parts.
- Wide Compatibility: Fits a broad range of hydraulic pumps and engines used in construction machinery, agricultural equipment, and industrial vehicles.
- Easy Installation: Designed with a standard threaded connection (1 ¾‑12 UN-2B), it can be installed or replaced without special tools.
Performance Characteristics
The WH 1257/1 delivers consistent pressure drop and flow rates, even under high load conditions. Its advanced filter media retains contaminants while allowing oil to circulate freely, reducing wear on bearings and seals. The filter’s design also minimizes the risk of clogging, extending service intervals.
Applications
This filter is ideal for:
- Construction equipment such as excavators, loaders, and backhoes.
- Agricultural machinery including tractors and combines.
- Industrial hydraulic systems used in manufacturing and processing plants.
- Utility vehicles operating in off‑road or heavy‑duty environments.
Maintenance Guidelines
Regular inspection is essential to maintain optimal performance. Replace the filter when:
- Oil becomes visibly contaminated or its color changes significantly.
- The pressure differential across the filter exceeds recommended limits.
- Scheduled maintenance intervals are reached, typically every 3,000–5,000 operating hours depending on usage conditions.
Installation Procedure
- Turn off the engine and allow the system to cool.
- Loosen the existing filter housing using a suitable wrench.
- Remove the old filter, discarding it properly.
- Place the new WH 1257/1 into the housing, ensuring correct orientation.
- Tighten the housing securely but avoid over‑tightening to prevent damage.
- Start the engine and check for leaks or abnormal pressure readings.
Quality Assurance
The WH 1257/1 is manufactured under stringent quality control protocols. Each unit undergoes rigorous testing for filtration efficiency, pressure drop, and durability before leaving the factory. This guarantees that every filter performs consistently in demanding operational environments.
Environmental Considerations
MANN‑FILTER designs its products with sustainability in mind. The WH 1257/1 uses recyclable materials where possible, and its efficient filtration reduces oil consumption and waste by extending the life of engine components.
