Original MANN-FILTER Oil Filter WH 945 – For Industrial, Agricultural and Construction Machinery

Overview of the Original MANN‑FILTER Oil Filter WH 945

The MANN‑FILTER WH 945 is a high‑performance hydraulic oil filter engineered for demanding industrial, agricultural and construction machinery. Designed with precision engineering, it delivers reliable protection for automatic transmissions, hydraulic systems and power units that operate under heavy loads and harsh operating conditions.

Design & Construction Excellence

The filter features a robust steel housing that resists corrosion and withstands high pressure environments. Inside, the multi‑stage filtration media is composed of premium synthetic fibers and activated carbon layers, providing superior contaminant capture while maintaining low flow resistance.

• Durable Housing: Corrosion‑resistant steel construction ensures longevity in aggressive chemical atmospheres.
• Multi‑Stage Media: Sequential filtration stages trap particles from 10 µm down to sub‑micron levels, protecting downstream components.
• Sealed Gasket System: The gasket design prevents leakage and guarantees a tight seal during installation.

Performance Characteristics

The WH 945 delivers exceptional filtration efficiency across a wide temperature range. Its high flow capacity reduces pressure drop, which translates into improved fuel economy and reduced wear on pumps and motors.

• Pressure Drop: < 0.5 bar at full load, ensuring minimal impact on system performance.
• Flow Rate: Maintains >90% of original flow under normal operating conditions.
• Particle Retention: Captures ≥99.9% of particles larger than 10 µm.

Compatibility and Application Scope

The WH 945 is engineered to fit a broad range of automatic transmissions, hydraulic pumps, and power units used in heavy machinery. Its standardized dimensions allow for straightforward integration into existing maintenance routines.

• Automatic Transmissions: Suitable for series such as John Deere 6, 6000, 6010, 6020, 6030 and similar models from Volvo, Renault, JCB, and others.
• Hydraulic Systems: Ideal for industrial hydraulic pumps that require high‑purity oil to prevent wear.
• Agricultural Equipment: Designed to handle the abrasive conditions typical of farming machinery.

Maintenance & Longevity

Regular replacement of the WH 945 ensures optimal system performance. The filter’s design allows for easy spin‑on installation, reducing downtime during maintenance intervals.

1. Inspection: Check for visible contamination or oil discoloration every 1,000–2,000 operating hours.
2. Replacement Interval: Recommended at 3,000–5,000 hours depending on load and environmental conditions.
3. Installation Tips: Ensure the gasket is clean and properly seated; avoid cross‑threading during tightening.

Key Benefits for Operators

• Extended Component Life: By removing contaminants, the filter protects pumps, motors, and gearboxes from premature wear.
• Reduced Maintenance Costs: Lower frequency of oil changes and fewer repairs due to contamination‑related failures.
• Improved System Efficiency: Minimal pressure drop preserves hydraulic power and reduces energy consumption.
• Reliability in Harsh Environments: Designed for high temperatures, dust, and chemical exposure common in construction sites.

Technical Specifications Summary

Conclusion

The MANN‑FILTER WH 945 stands out as a reliable, high‑performance oil filter for industrial, agricultural and construction machinery. Its robust construction, superior filtration capability, and ease of maintenance make it an essential component for operators seeking to protect critical hydraulic systems and automatic transmissions from contamination and wear.
