The Sy-Klone CYCLONE45 Air Pre-Cleaner (model CYCLONE-45/MM) is a high-performance pre-cleaner designed to significantly extend the life of engine air filters in demanding environments. It effectively removes up to 90% of airborne contaminants, including dust, dirt, and debris, before they reach the main air filter. This genuine Sy-Klone unit is suitable for applications requiring an airflow range of 450-750 CFM (212-354 L/s) and features a 127 mm (5-inch) inlet/outlet diameter, reducing maintenance costs and downtime for heavy-duty machinery.
