Air Cleaner/Pre-Cleaner Full View Inlet:65mm (A)

Compatible with the following equipment:

A **pre-cleaner** on an excavator is a device installed in the air intake system to remove large particles, debris, and moisture from incoming air **before** it reaches the primary air filter. This component acts as a first line of defense, enhancing the efficiency and longevity of the main filtration system. Below are key details about its function, types, and benefits:

### ⚙️ 1. **Purpose and Function**
   - **Contaminant Removal**: Pre-cleaners use centrifugal force or inertial separation to eject large debris (e.g., dust, leaves, water droplets) from the intake air. For example, Donaldson's Strata™ Cap removes up to 96% of contaminants, including 99% of particles ≥20 microns .
   - **Protection for Primary Filters**: By capturing coarse particles, they prevent premature clogging of the main air filter, which is critical since diesel engines require ~8,000 gallons of clean air per gallon of fuel burned .
   - **Moisture Management**: Some models (e.g., in-line separators) achieve 80% water removal efficiency, protecting the engine from corrosion .
