Instruction Manual

The 757 South Dakota Seed Blower utilizes airflow, which is generated by a blower motor and as that air passes through a column (1½", 3" or 4") the air lifts light fluffy material or empty seed hulls into the top beveled area of the column, while larger heavier good seed stays at the bottom. The motor is ⅓HP, 110V/60HZ OR 220V/60Hz and operates at 3,450 RPM. The 757/A 220V/50HZ unit is ½HP and 2,850 RPM.

Separations are accurately controlled by a calibrated valve cap in the top of the column. Sold without columns.

We offer three column sizes: 1½" I.D. x 23¼" H, 3" I.D. x 34¼" H, and 4" I.D. x 35¼"H, constructed of clear Plexiglas. This permits easy viewing of the calibrated air valves on all three-column sizes. The 757 base measures 20" L x 20" W x 30½" H. Additional features include a 5-minute timer, on/off control knob and a hand brake to stop the motor instantly to eliminate coasting of the blower fan.

Ship wt. 155 lbs. Net. wt. 110 lbs. Ship Dims (757 Cabinet Only): 25in x 20in x 40in

Seedblower Cups and Tube Sets

Air columns are precision built to trap lightweight seed and chaff, collecting pure seed in the "cup" located at the bottom of the column. The cup has a wire mesh bottom to prevent seed from falling into the fan. Mesh sizes are: 1½" 100 mesh, 3" 50 mesh and 4" 30 mesh. Ship wt. 5 lbs.

Also available is the 757-RC, 4" tube with removable cup for easy access to the cleaned sample (see photos to the left) and with removable containers off the side of the column, in lieu of baffles as in the standard column
