GRAIN CONDITIONING / CLEANING SYS.. / … kleenair vacuum grain sieve A SIMPLE WAY TO SIEVE GRAIN. The KLEENair Vacuum Grain Screener is significantly better than the ASPIRATOR Cleaners because of the SCREENING ACTION where the Nylon Tipped, Hanger-Bearing Auger moves the grain across a perforated tube, enclosed in a heavy metal hopper, which has a vacuum environment inside Broken kernels, cracks, splits, fines and bees wings are screened here, drawn out, and blown away by the high-pressure blower. The fines are totally enclosed from the KLEENair Screener to the fines storage equipment. This helps keep the area around the dryer clean and free from blowing debris.
