MANN‑FILTER HD 45/3 Hydraulic Oil Filter
The HD 45/3 is a high‑performance hydraulic oil filter engineered by MANN‑FILTER for utility vehicles and industrial hydraulic systems. Designed to meet the rigorous demands of heavy duty applications, it delivers superior protection against contaminants while maintaining optimal flow characteristics.
Key Design Features
- Advanced Filter Media: Utilises a multi‑layered media structure that captures particles as small as 0.5 µm, ensuring clean hydraulic fluid and extending the life of pumps, valves, and actuators.
- Robust Housing: Constructed from high‑strength aluminium alloy with a corrosion‑resistant finish, guaranteeing durability in harsh operating environments.
- Low Pressure Drop: Engineered to minimise pressure loss across the filter, preserving system efficiency and reducing energy consumption.
- Quick‑Fit Connection: Features a standard threaded interface (M10x1.5) compatible with most hydraulic lines and fittings used in utility vehicles.
- High Flow Capacity: Rated for flow rates up to 120 L/min at operating pressure, suitable for large displacement pumps and high‑speed hydraulic circuits.
Performance Specifications
| Parameter | Value |
|---|---|
| Filter Size | 45 mm diameter, 3 mm depth |
| Maximum Operating Pressure | 350 bar |
| Operating Temperature Range | -40 °C to +120 °C |
| Pressure Drop (at 100 L/min) | ≤ 2.5 bar |
| Filter Media Life (clean fluid) | ≈ 90 days or 10,000 km of vehicle operation |
| Compatibility | All standard hydraulic oils (ISO 32, ISO 46, ISO 68, ISO 92, ISO 140) |
Applications
The HD 45/3 is ideal for:
- Utility vehicles such as excavators, backhoes, and compactors.
- Industrial hydraulic machinery including presses, lathes, and CNC machines.
- Off‑highway equipment like loaders, graders, and wheel loaders.
- Marine propulsion systems where reliable hydraulic performance is critical.
Installation Guidelines
- Turn off the hydraulic system and relieve all pressure.
- Disconnect the existing filter housing, ensuring no fluid leaks.
- Clean the mounting surface with a non‑abrasive cloth; avoid oil residue.
- Thread the new HD 45/3 filter onto the line using left‑handed torque to prevent cross‑threading.
- Tighten until snug, then apply a small amount of hydraulic oil to the threads for lubrication.
- Re‑pressurise the system gradually and check for leaks.
Maintenance & Replacement Schedule
For optimal performance, replace the filter according to the following schedule:
- Every 6 months or 5,000 km, whichever comes first.
- After any major hydraulic system service or oil change.
- If the pressure drop exceeds the specified limit during operation.
Benefits of Choosing MANN‑FILTER HD 45/3
- Extended Equipment Life: By trapping fine particles, it protects critical components from wear and tear.
- Consistent System Performance: Low pressure drop ensures that hydraulic power remains stable under load.
- Reliability in Extreme Conditions: Withstands wide temperature ranges and high pressures typical of utility vehicle operations.
- Easy Integration: Standard thread size and compact design allow for quick swaps without specialised tools.
Quality Assurance
The HD 45/3 undergoes rigorous testing in accordance with ISO standards, including:
- Pressure endurance tests up to 350 bar.
- Temperature cycling between -40 °C and +120 °C.
- Flow rate verification at various pressures.
- Contaminant retention analysis using laser diffraction methods.
Conclusion
The MANN‑FILTER HD 45/3 Hydraulic Oil Filter represents a blend of robust engineering, precise manufacturing, and proven performance. Whether you operate heavy machinery on construction sites or maintain critical hydraulic systems in industrial plants, this filter delivers the reliability and protection required to keep your equipment running smoothly.
