This Donaldson Pre-Cleaner is designed to enhance air filter longevity by eliminating up to 90% of dirt and contaminants before they reach the filter. Operating as part of a scavenged flow system, it consistently expels pre-cleaned contaminants through the exhaust flow. Made from durable, corrosion-resistant steel, this Pre-Cleaner is particularly suited for equipment in very heavy dust/debris environments. With dimensions of 13.33 inches in height, 9.00 inches maximum body diameter, and a 9.00-inch outlet diameter, it delivers a rated flow of 21.8 m³/min (770 cfm) and maintains a restriction of 127 mm H2O (5.00 inches H2O).
