Air Vacuum

Supersonic Air Vacuum

Vacuum Technology

The vacuum can use the same compressor as the Air Knife, as long as the compressor size is not less than 100 psi/175 cfm. Nozzles at the inside bottom of the suction tube direct the air stream upward, creating a vacuum at the tube entrance so as to suck crumbled soil, gravel (< 2 3/4 inch), and/or water from the excavation. The materials travel up the tube, and are deposited at/near the end of a 3.5" I.D. or 4" I.D. flexible discharge hose. The diameter and length of the discharge hose are determined by a combination of compressor rating and customer preference.

Vacuum Operation

The vacuum is held with two hands, at a small angle to vertical. The angle assures that sufficient air is drawn into the suction to draw material into the barrel. There is an integral air gage on the Air Vacuum. By observing the gage pressure, the operator can determine if pressure is adequate at the tool. Normal operating pressure will be less than the Air Knife, Air pressure being not as critical for the Air Vacuum as it is for the Air Knife.

Vacuum Safety

The operator can wear normal work clothes, however many operators prefer to wear coveralls. Ear, eye and hard hat protection is required. A face shield is desirable. Other normal safety precautions associated with compressed air must also be employed.
