This is the 1.5 horsepower CenturionPro Mini replacement blower that fits our most popular home trimming system. The 1.5hp blower works with the leaf collector in order to produce the 2000 CFM airflow capacity necessary for proper suction. As a result, this suction is imperative to produce the sharpest and cleanest cut in the industry. When proper suction is lacking, the flower will still move through the tumbler. However, it will not pull tight enough to the drum to produce a quality cut.
