Original MANN-FILTER Air Filter CF 923 - Secondary Air Filter Element – For utility vehicles

MANN‑FILTER CF 923 Secondary Air Filter Element

The MANN‑FILTER CF 923 is a high‑performance secondary air filter element designed specifically for utility vehicles, commercial trucks, and off‑road applications. Engineered with precision, this filter ensures optimal airflow while protecting the engine from contaminants that can compromise performance and longevity.

Key Features and Design Excellence

• Advanced Filtration Technology: The CF 923 employs a multi‑layered filtration media that captures fine dust, grit, and oil mist. This design delivers superior protection for the engine’s intake system.
• Durable Construction: Constructed from high‑quality polypropylene and reinforced with a robust frame, the filter resists deformation under pressure and withstands harsh operating conditions.
• Optimized Airflow: The element is engineered to maintain low resistance while providing maximum filtration efficiency. This balance reduces engine load and improves fuel economy.
• Easy Installation: Designed for quick fitment, the CF 923 fits standard secondary air filter housings without modification. Its secure mounting system prevents leaks and ensures a tight seal.
• Long Service Life: With its high‑capacity media, the filter can endure extended periods between changes, especially in environments with moderate particulate load.

Applications Across Industries

The CF 923 is compatible with a wide range of utility vehicles and commercial trucks. Its versatility makes it suitable for:

• Heavy‑duty pickups and delivery vans
• Construction equipment such as excavators and loaders (when adapted to secondary air systems)
• Agricultural machinery requiring robust filtration in dusty fields
• Marine vessels with auxiliary engines that benefit from secondary air filtration

Performance Metrics

The filter’s performance is quantified by its pressure drop and particulate removal efficiency:

• Pressure Drop: Typically around 0.5–1.2 kPa at standard airflow rates, ensuring minimal impact on engine breathing.
• Particulate Removal Efficiency: Up to 99.9% for particles in the 0.3–10 µm range, safeguarding critical engine components.
• Oil Mist Capture: Capable of trapping oil mist up to 95%, reducing oil consumption and emissions.

Installation Guide

1. Prepare the Vehicle: Ensure the engine is cool and disconnect any battery connections for safety.
2. Remove Existing Filter: Open the secondary air filter housing, release any clamps or screws, and carefully remove the old element.
3. Inspect Housing: Clean the interior of the housing to remove debris that could compromise the new filter’s seal.
4. Install CF 923: Place the new filter into the housing, aligning it with the mounting points. Secure with clamps or screws as required.
5. Verify Seal: Check for any gaps or leaks around the edges of the filter. Tighten all fasteners to manufacturer specifications.
6. Reconnect Battery and Test: Reconnect the battery, start the engine, and observe for proper airflow and absence of unusual noises.

Maintenance Tips

• Inspect the filter every 6–12 months or after significant exposure to dusty environments.
• Avoid cleaning the CF 923 with water or solvents; replace it if contamination is severe.
• Store unused filters in a dry, dust‑free environment to preserve media integrity.
