Original MANN-FILTER Hydraulic filter WH 980 – For industry, agricultural and construction machinery

MANN‑FILTER WH 980 Hydraulic Filter

The WH 980 is a high‑performance hydraulic filter designed for demanding industrial, agricultural and construction machinery. It delivers superior protection for hydraulic systems that operate under heavy loads, extreme temperatures and abrasive environments.

Key Design Features

• Robust Construction: The filter housing is made from high‑strength alloy steel, ensuring durability against vibration, impact and corrosion. The internal components are engineered to withstand high pressure differentials.
• Advanced Filter Media: A multi‑layer media assembly captures particles as small as 0.5 µm. This guarantees clean hydraulic fluid, extending the life of pumps, valves and actuators.
• Wide Operating Temperature Range: The filter operates reliably from -40 °C to +120 °C, making it suitable for cold climates and high‑temperature industrial processes.
• High Flow Capacity: With a flow rate of up to 250 L/min at 200 bar, the WH 980 maintains system performance without adding significant pressure drop.
• Easy Installation: The standard 1‑3/8″‑12 UNF thread and 90° swivel mounting allow quick replacement in most hydraulic lines. A built‑in pressure gauge provides instant visual feedback on filter status.

Applications Across Industries

The WH 980 is engineered for a broad spectrum of machinery:

• Construction Equipment: Excavators, backhoes, loaders and bulldozers that rely on hydraulic power for lifting, digging and moving heavy loads.
• Agricultural Machinery: Tractors, combines, harvesters and irrigation systems where reliable hydraulics are critical for field operations.
• Industrial Automation: CNC machines, press equipment and robotic arms that require precise hydraulic control.
• Off‑Highway Vehicles: Mining trucks, graders and dump trucks operating in dusty or sandy environments.

Technical Specifications

Performance Benefits

• Extended Component Life: By trapping contaminants before they reach pumps and valves, the WH 980 reduces wear and tear, lowering maintenance costs.
• Improved System Efficiency: Minimal pressure drop ensures that hydraulic power is delivered efficiently to actuators and tools.
• Reliability in Harsh Conditions: The filter’s robust construction and wide temperature tolerance make it dependable in extreme environments.
• Quick Replacement: Standard thread size and swivel mounting allow technicians to swap the filter without specialized tools, minimizing downtime.

Installation & Maintenance Guidelines

1. Turn off the hydraulic system and relieve pressure before removing the old filter.
2. Unscrew the existing filter using a wrench or socket set. Be careful to avoid damaging the housing threads.
3. Inspect the new WH 980 for any visible defects. Ensure that the gasket is intact and properly seated.
4. Screw in the filter clockwise until it is snug, then tighten an additional quarter turn with a torque wrench (recommended torque: 12 Nm).
5. Reconnect the hydraulic lines and gradually restore pressure while monitoring for leaks.
6. Check the built‑in gauge to confirm that the filter is operating within normal parameters. Replace the filter when the gauge indicates a significant drop in flow or increased pressure differential.

Compatibility Summary

The WH 980 is compatible with a wide range of hydraulic systems across major manufacturers:

• Volvo, John Deere, JCB, Caterpillar, Case IH, Hitachi, and many others.
• Suitable for both automatic transmissions and work‑hydraulic applications.
• Fits standard 1‑3/8″‑12 UNF threaded lines found in most heavy machinery.

Conclusion

The MANN‑FILTER WH 980 Hydraulic Filter stands out as a reliable, high‑performance solution for protecting hydraulic systems in industrial, agricultural and construction settings. Its robust design, advanced filtration media, and ease of installation make it an essential component for maintaining operational efficiency and extending equipment lifespan.
