Description

Product Overview

The Sy-Klone 9004 Precleaner protects very large engines that work in extreme dust. It uses a centrifugal airflow design that spins incoming air inside the housing. Because of this rotation, heavier debris moves outward and exits through discharge ports. Cleaner air then continues toward the engine’s main filter.

The 9004 is built for equipment that demands extremely high airflow. With an 8-inch inlet and a 1150–1400 CFM rating, it fits heavy machinery in mining, construction, forestry, waste handling, and industrial operations. It also works without wiring since it relies entirely on airflow. This simple design reduces maintenance while supporting longer engine-filter life.

Applications & Fitment

The Sy-Klone 9004 is used on high-horsepower engines found in:

• Large mining trucks and loaders

• Heavy construction excavators and dozers

• Industrial diesel-power units

• High-output agricultural harvesters

• Large forestry machines

• Severe-duty waste-handling and landfill equipment

These machines often run in extreme dust, so a strong precleaner is essential for engine protection.

Maintenance

Inspect the precleaner often because dust and debris can collect around the housing and discharge ports. Clean away loose material and confirm that air flows freely. Replace the unit if cracks appear or if debris no longer ejects correctly. Regular maintenance helps protect engine airflow and performance.
