The ASPIRATOR Kit is available for SELF-POWERED units. This option is available for folks who want to screen and aspirate. It can be added to a new or existing KLEENair Screener providing you have the 3 HP "Little Bertha" Blower option. The standard 1 HP blower does a good job of blowing fines and bees wing away from the screening operation, or it can handle the ASPIRATING job alone. However, it requires the additional power of the "Little Bertha" 3 HP blower to do both screening and aspirating simultaneously. The 3 horsepower "Little Bertha" Blower improves the cleaning action of any KLEENair Screener by providing more airflow, more vacuum, and more cleaning power. The standard one horsepower unit requires 4" tubing to take fines away. The three horsepower, "Little Bertha" requires 6" tubing for the take-away. Both the 1 HP (4" line) and 3 HP (6" line) blowers are capable of moving screenings 100' or more from the screener.
