Original MANN-FILTER Secondary Air Filter CF 922 – For Industrial, Agricultural and Construction Machinery

Overview of the MANN‑FILTER CF 922 Secondary Air Filter

The MANN‑FILTER CF 922 is a high‑performance secondary air filter engineered for use in demanding industrial, agricultural and construction machinery. Designed to provide reliable protection against dust, grit and other contaminants, it ensures optimal engine performance, reduced wear and extended service intervals.

Key Design Features

• Robust Construction: The filter housing is made from durable polypropylene with reinforced seams that resist cracking under vibration and temperature extremes.
• High‑Efficiency Media: A multi‑layer fibrous media delivers a filtration efficiency of up to 99.9% for particles as small as 5 µm, while maintaining low pressure drop.
• Optimized Airflow: The CF 922’s geometry is engineered to provide maximum airflow at standard engine operating pressures, reducing the risk of back‑pressure and ensuring consistent air supply.
• Easy Installation: Snap‑fit mounting brackets allow for quick replacement without the need for special tools or extensive disassembly.

Applications in Industrial Machinery

The CF 922 is specifically tailored to meet the rigorous demands of industrial equipment such as:

• Heavy‑Duty Generators – Maintaining clean air intake for generators that operate continuously in dusty environments.
• Mining and Quarrying Machines – Protecting engines from abrasive particles encountered during excavation and material handling.
• Manufacturing Plant Equipment – Ensuring reliable operation of conveyor systems, mixers and other machinery that rely on clean air for optimal performance.

Applications in Agricultural Machinery

Agricultural operators benefit from the CF 922’s resilience to dust, pollen and soil particles. Typical uses include:

• Tractors and Harvesters – Providing clean air for engines that run on rough terrain.
• Irrigation Pumps – Protecting pumps from contamination that could impair flow or cause wear.
• Farm Implements – Ensuring consistent performance of equipment such as planters, sprayers and tillers.

Applications in Construction Vehicles

The CF 922 is also ideal for construction vehicles that operate in dusty or gravelly sites:

• Excavators and Backhoes – Maintaining engine reliability during prolonged operation.
• Bulldozers and Loaders – Protecting air intake systems from fine particles generated by earthmoving activities.
• Cranes and Forklifts – Ensuring clean air for hydraulic pumps and engine components in indoor and outdoor settings.

Performance Metrics

Maintenance and Longevity

The CF 922 is designed for extended service life. Recommended maintenance includes:

• Visual Inspection: Check for media saturation or physical damage every 1,000 hours of operation.
• Cleaning Procedure: If the filter is reusable, gently rinse with clean water and allow to dry completely before reinstallation.
• Replacement Interval: Replace after 2,500 hours or when pressure drop exceeds specified limits.

Installation Guide

1. Turn off the engine and allow it to cool.
2. Locate the secondary air filter housing on the engine block.
3. Remove the existing filter by releasing the snap‑fit clips.
4. Insert the new CF 922, aligning the mounting tabs with the housing.
5. Secure the filter by engaging all snap‑fit clips until a firm lock is achieved.
6. Verify that the filter is seated correctly and that no gaps are present.

Compatibility Summary

The CF 922 is compatible with a wide range of engine models across multiple manufacturers. It is specifically engineered to fit:

• Diesel Engines used in construction and agricultural equipment.
• Gasoline Engines found in smaller industrial machines.
• Both single‑stage and dual‑stage air intake systems where a secondary filter is required.
