Mann Filter W W 1150/91 Drive Elements

Overview of the Mann Filter W W 1150/91 Drive Element

The Mann Filter W W 1150/91 Drive Element is a high‑performance hydraulic oil filter designed for demanding industrial and commercial applications. Engineered with advanced filtration technology, it delivers superior protection for hydraulic systems that operate under extreme pressure, temperature, and load conditions. The element’s robust construction ensures long service life while maintaining tight tolerances to prevent leakage and contamination.

Key Features

• High‑Efficiency Filtration: Utilizes a multi‑stage filtration media that captures particles as small as 1 µm, ensuring clean hydraulic fluid and extending component life.
• Durable Construction: Made from high‑strength polypropylene housing with reinforced seals to withstand temperatures up to 200 °C and pressures exceeding 3000 psi.
• Low Pressure Drop: Designed for minimal resistance, the element maintains optimal flow rates even in high‑capacity systems.
• Easy Installation: Features a quick‑connect threaded interface (M10×1.5) compatible with standard hydraulic fittings, allowing rapid replacement without specialized tools.
• Long Service Life: Rated for up to 12 000 operating hours under typical service conditions, reducing maintenance frequency and downtime.

Technical Specifications

Installation Guide

1. Preparation: Ensure the hydraulic system is depressurized and cooled to a safe temperature before beginning work.
2. Remove Existing Filter: Unscrew the old filter element using a wrench or socket set. Dispose of the used filter according to local environmental regulations.
3. Inspect Fitting: Check the threaded connection for wear, corrosion, or debris that could compromise sealing.
4. Install New Element: Align the threaded end with the fitting and hand‑tighten. Use a torque wrench to achieve the manufacturer’s recommended torque (typically 12 Nm).
5. Verify Seal Integrity: Inspect for leaks around the O‑rings and gasketed flange after initial pressure is applied.
6. System Flush: Run clean hydraulic fluid through the system to purge any trapped air before returning to normal operation.

Maintenance Tips

• Regularly inspect the filter housing for cracks or deformation, especially after high‑temperature exposure.
• Check O‑ring condition; replace if signs of hardening or swelling are observed.
• Maintain a clean work environment to prevent particulate contamination during installation.
• Document each replacement with date and operating hours for future reference.
