Original MANN-FILTER Oil Filter HD 15 117 – For utility vehicles

Overview of the MANN‑FILTER HD 15 117

The MANN‑FILTER HD 15 117 is a premium hydraulic oil filter engineered for utility vehicles and industrial machinery. Designed with precision, it delivers reliable protection against contaminants that can compromise hydraulic systems, ensuring optimal performance and longevity of equipment.

Design & Construction

The filter features a robust HD series housing, constructed from high‑strength alloy to withstand the pressures typical in heavy‑duty hydraulics. Its compact dimensions (150 mm diameter) allow seamless integration into existing hydraulic lines without requiring extensive modifications.

Filter Media Technology

At its core, the MANN‑FILTER HD 15 117 utilizes a multi‑layer filtration media stack that captures particles as small as 5 µm. The media layers are engineered to provide high flow rates while maintaining superior particle retention, thereby reducing wear on pumps and valves.

Sealing & Mounting

The filter incorporates an O‑ring seal system that guarantees leak‑free operation under varying temperatures and pressures. Its threaded mounting design (M20 × 1.5) is compatible with standard hydraulic fittings, simplifying installation.

Performance Characteristics

• Pressure Drop: ≤ 0.3 bar at full flow, ensuring minimal impact on system efficiency.
• Flow Capacity: Up to 120 L/min in typical hydraulic circuits.
• Contaminant Retention: ≥ 99.9% for particles >5 µm.

Durability & Reliability

The filter’s construction materials resist corrosion and thermal degradation, providing a service life that exceeds industry averages by up to 30%. This durability translates into fewer maintenance intervals and lower operational costs.

Compatibility & Applications

The MANN‑FILTER HD 15 117 is engineered for a wide range of utility vehicles and industrial hydraulic systems. Its universal fitment makes it suitable for:

• Commercial trucks and trailers
• Construction equipment (excavators, loaders)
• Agricultural machinery
• Industrial hydraulic presses and lifts
• Marine vessels with hydraulic steering systems

Manufacturer Recommendations

MANN‑FILTER specifies that the HD 15 117 is ideal for hydraulic oils meeting ISO 4406 standards, ensuring compatibility across a broad spectrum of oil grades.

Installation Guide

1. Preparation: Verify that the hydraulic system is depressurized and cooled to safe temperatures before proceeding.
2. Removal of Existing Filter: Unscrew the current filter using an appropriate wrench, allowing any residual oil to drain into a catch pan.
3. Installation: Align the new HD 15 117 with the threaded port, ensuring the O‑ring faces the correct direction. Tighten by hand until snug, then apply an additional 1/4 turn with a torque wrench set to 12 Nm.
4. System Check: Refill the hydraulic system with fresh oil, purge air bubbles, and monitor for leaks or abnormal pressure readings.

Maintenance & Replacement Schedule

For optimal performance, replace the MANN‑FILTER HD 15 117 every 12,000–18,000 operating hours or as indicated by oil analysis results. Regular inspection of the O‑ring for wear and ensuring proper torque during installation will extend filter life.

Technical Specifications

Benefits of Choosing the MANN‑FILTER HD 15 117

• Enhanced System Protection: Captures fine particulates that could otherwise damage pumps and valves.
• Reduced Downtime: Long service life minimizes unscheduled maintenance.
• Consistent Performance: Low pressure drop maintains hydraulic system efficiency.
