Filtering system for cleaning air
First Claim
1. A filtering system for cleaning air comprising:
- a first annular chamber having a quantity of liquid at the bottom thereof;
inlet means for directing air across the upper surface of said liquid in a substantially tangential direction to cause said air to circulate in a first circular direction within said first chamber, said inlet means including an inlet pipe extending into the interior of said first annular chamber from the bottom thereof;
a second annular chamber concentric with said first chamber and in fluid communication with said first chamber to thereby allow said circulating air from said first chamber to pass into said second chamber;
means for causing air within said second chamber to circulate in a second circular direction, opposite to said first circular direction, andoutlet means for allowing filtered air to exit from said second chamber.

Abstract
The present invention is a three stage water-from-air-filter system which can be used in combination with substantially any household vacuum cleaner. The system includes a main cylindrically shaped body and a hollow cylinder within the main body. The main body and cylinder form a ring-shaped chamber. The chamber has a spherical bottom partially filled with water. The hollow cylinder is made of a large pipe and a small pipe. The large pipe has an areohydrodynamic separator. An entrance nozzle may be located on either the main body or on the small pipe. Regardless of where the nozzle is located, polluted air enters the ring-shaped chamber through the nozzle. In the chamber the air mixes with the water. The air and water mixture is centrifugally separated several times through the concentric cylinders within the filter system to ensure a high quality of cleaning.
