Original MANN-FILTER Oil Filter W 920/21 – Hydraulics filter – For passenger cars and utility vehicles

Product Overview

The MANN‑FILTER Original Oil Filter W 920/21 – Hydraulics filter is a high‑performance filtration solution engineered for passenger cars and utility vehicles. Designed with precision engineering, it delivers reliable protection for hydraulic systems in a wide range of automotive platforms.

Key Design Features

• Spin‑On Construction: The filter features a robust spin‑on mounting system that ensures a secure fit and easy installation across compatible models.
• 3/4‑inch, 16 UNF Thread: Standardized threading guarantees compatibility with most hydraulic fittings found in modern vehicles.
• High‑Efficiency Filter Media: Advanced filtration media captures fine particles and contaminants, extending the life of hydraulic components.
• Non‑Return Valve: Integrated valve prevents backflow, maintaining system integrity during operation.
• Durable Housing: Constructed from high‑strength polymer to resist corrosion and withstand harsh operating conditions.

Performance Characteristics

The W 920/21 filter is engineered to meet stringent performance criteria:

• Particle Retention: Capable of retaining particles as small as 5 µm, ensuring clean hydraulic fluid.
• Pressure Drop: Maintains a low pressure differential (≤ 0.15 bar) across the filter during normal operation.
• Flow Capacity: Supports flow rates up to 120 L/min, suitable for high‑performance hydraulic systems.
• Temperature Range: Operates effectively between -40 °C and +120 °C, accommodating extreme climates.

Compatibility Matrix

The filter is designed to fit a broad spectrum of vehicle makes and models. Below is an illustrative list of compatible platforms (not exhaustive):

Installation Guidelines

1. Preparation: Ensure the hydraulic system is depressurized and drained of old fluid before removal.
2. Removal: Unscrew the existing filter using a suitable wrench; discard or recycle according to local regulations.
3. Installation: Align the new W 920/21 filter with the mounting surface, ensuring the non‑return valve faces the correct direction. Tighten by hand until snug, then give an additional quarter turn with a torque wrench set to 4 Nm.
4. Re‑fill: Refill the hydraulic system with fresh fluid, checking for leaks.
5. Test Run: Operate the vehicle’s hydraulic functions to confirm proper operation and verify that pressure readings remain within manufacturer specifications.

Maintenance & Replacement Interval

For optimal performance, replace the filter at every 10,000 km or 12 months, whichever comes first. In high‑contamination environments (e.g., dusty construction sites), consider a shorter interval of 5,000 km.

Benefits to Vehicle Owners

• Extended Component Life: By trapping contaminants, the filter protects pumps, valves, and actuators from premature wear.
• Consistent Hydraulic Performance: Maintains system pressure and flow characteristics, ensuring reliable operation of steering, braking, and suspension systems.
• Reduced Maintenance Costs: Fewer repairs and replacements due to contamination damage translate into long‑term savings.
• Environmental Responsibility: Proper filtration reduces the release of particulate matter into the environment during fluid disposal.

Quality Assurance & Compliance

The W 920/21 filter is manufactured under strict quality control protocols, meeting or exceeding industry standards such as ISO 9001:2015. It complies with automotive safety and environmental regulations, ensuring that it can be confidently used in both commercial fleets and private vehicles.

Conclusion

The MANN‑FILTER Original Oil Filter W 920/21 – Hydraulics filter represents a blend of engineering excellence and practical reliability. Its robust construction, high filtration efficiency, and broad compatibility make it an indispensable component for maintaining the integrity of hydraulic systems in passenger cars and utility vehicles alike.
