Original MANN-FILTER Oil Filter HD 622/1 – For utility vehicles

MANN‑FILTER HD 622/1 Hydraulic Oil Filter

The HD 622/1 is a premium hydraulic oil filter engineered by MANN‑FILTER, the world leader in filtration technology. Designed for high‑performance utility vehicles and industrial hydraulics, this filter delivers exceptional protection against contaminants while maintaining optimal flow rates under demanding operating conditions.

Key Design Features

• High‑Efficiency Filtration: The filter employs a multi‑layer media system that captures particles as small as 0.5 µm, ensuring the hydraulic fluid remains clean and free from abrasive debris.
• Robust Construction: Made with a durable polypropylene housing, the cartridge resists corrosion and withstands high pressure environments typical of heavy‑duty hydraulics.
• Low Pressure Drop: Advanced media design minimizes resistance to flow, preserving system performance and reducing energy consumption.
• Wide Compatibility: The HD 622/1 fits a broad range of hydraulic systems, including those used in construction machinery, agricultural equipment, and industrial workstations. It is specifically engineered for use with the Linde Krone, Wirtgen Zetor, and other high‑pressure hydraulic platforms.
• Easy Installation: The filter features a standard cartridge shape that can be swapped without special tools, allowing quick maintenance and minimal downtime.

Performance Specifications

Applications Across Industries

The HD 622/1 is trusted by operators worldwide for its reliability in:

• Construction Equipment: Excavators, loaders, and backhoes that rely on high‑pressure hydraulics for lifting and digging.
• Agricultural Machinery: Tractors, harvesters, and irrigation systems where clean fluid is essential to prevent wear.
• Industrial Workstations: CNC machines, presses, and assembly line robots that demand precise hydraulic control.
• Marine and Offshore Platforms: Rigs and vessels operating in harsh environments where contamination can lead to costly downtime.

Maintenance Benefits

By incorporating the HD 622/1 into your maintenance schedule, you gain:

• Extended Hydraulic Component Life: Protects pumps, valves, and actuators from particulate damage.
• Consistent System Performance: Maintains pressure stability and flow rates over longer intervals between changes.
• Reduced Operating Costs: Lower energy consumption due to minimal pressure drop and fewer repairs.
• Environmental Compliance: Helps meet stringent regulations on fluid contamination and waste management.

Installation Guide

1. Turn off the hydraulic system and relieve all pressure.
2. Remove the existing filter cartridge by unscrewing the housing cap.
3. Inspect the housing for wear; replace if necessary.
4. Insert the new HD 622/1 cartridge, ensuring it is seated fully.
5. Screw the housing cap back on and tighten to the manufacturer’s torque specification.
6. Re‑pressurize the system gradually while monitoring for leaks or abnormal pressure drops.
