This is the 1 horsepower Tabletop replacement blower that fits our popular home grow trimming system. This blower works in conjunction with the leaf collector to produce the 1800 CFM airflow capacity required for proper suction. As a result, this suction is imperative for producing the sharpest and cleanest cut in the industry. When proper suction is lacking, the buds will still move through the tumbler. However, it will not pull them tight enough to the drum for a quality cut.
